Installation Guidepage 4 18-HD72D1-1 4. Installation4.1 LocationThe 824 Control is designed for installation in climate controlled living spaces. Place the unit in a central location with good circulation.For proper temperature sensing, avoid mounting the Control where it will be exposed to heat radiated from lamps, sun light, fireplaces or any other radiant heat source.Avoid locations close to windows, behind doors or alcoves with poor air circulation, adjoining outside walls, or doors that lead to the outside.Select a location that prevents the Control from being directly exposed to air currents from supply registers or ceiling fans.Mount the Control on a section of interior wall that does not contain hor or cold water pipes or duct work.Important: The 824 Control utilizes a 4.5” color touch screen. This screen generates heat which is vented out the top of the Control utilizing natural convection. If an air source is directed at or from above, heat from the screen can be trapped within the Control body and can cause the indoor temperature to be biased. Refer to “Figure 1. Placement of the 824” on page 4 4.2 Network ConnectionsTo take advantage of the full range of features on the 824 Control, it should be connected to the Internet. This is possible using either a wireless or a wired connection.Wireless ConnectionsIf the 824 Control will be connected to the Internet using the built-in wireless feature, choose a mounting location that ensures adequate signal strength from the internet router.Tips to Help Maximize Signal Strength: — Do not mount the Control more than 30 feet from the wireless router — There should be no more than three interior walls between the Control and the router. — Do not mount the Control in areas where electromagnetic emissions from other devices, appliances or wiring can interfere with the Control’s communication. (i.e. wireless phones, security systems, wireless internet cameras). — Do not mount the Control in recessed areas, near metal objects, or near structures. (i.e. doors, appliances, entertainment centers or shelving units). — Do not mount the Control closer than 2 inches to any pipes, duct work, or other metal obstructions. — Do not have metal obstructions, concrete or brick walls between the Control and the router it.Wired ConnectionsThe 824 Control may be connected to the Internet using its built-in RJ-45 connector. When using a wired connection, verify that a CAT 5 or better Ethernet cable with a male RJ-45 connector is present from the router to the Control.4.3 MountingFollow these steps to mount the 824 Control to the wall.1. Turn OFF all power to heating and cooling equipment.2. If an existing thermostat is being replaced:a. Remove the existing thermostat from the wall.b. Record color and terminal marking of each wire.c. Disconnect the wires from the existing thermostat being careful not to allow them to fall back into the wall.3. Carefully pry the sub-base away from the 824 Control using a small flat-blade screwdriver. Note that the tight fit is normal and ensures that the Control is held securely to the sub-base when mounted on the wall.4. Route the thermostat wires through the opening on the sub-base.5. If using a wired Internet connection, route the Ethernet cable through the opening.6. Place the sub-base against the wall in the desired location and mark the wall through the mounting holes. If you are using a wired Internet connection, be sure to mark the cutout for the RJ-45 Holder (see “Figure 2. Mark the Mounting Holes”).IncorrectPlacementof the 824Ceiling FanNatural heatdissapationfrom the 824Touch ScreenOnboardThermistor5 FEETOptimumZone2 FEETCorrectPlacementof the 950CorrectPlacementof the 824Heat from the 824 screen may be trapped within the body of the Control by an external top-down airflow source, such as a ceiling fan.The onboard thermistor may be biased by this heat causing the displayed indoor temperature to be elevated.IncorrectPlacementof the 824Ceiling FanNatural heatdissapationfrom the 824Touch ScreenOnboardThermistor5 FEETOptimumZone2 FEETCorrectPlacementof the 950CorrectPlacementof the 824Heat from the 824 screen may be trapped within the body of the Control by an external top-down airflow source, such as a ceiling fan.The onboard thermistor may be biased by this heat causing the displayed indoor temperature to be elevated.FIGURE 1.

If using a wired Ethernet connection, follow these step and refer to “Figure 3. Attach RJ-45 Holder to Sub-base”.a. With the Sub-base and RJ-45 Holder oriented as shown, press the holder into the Sub-base.b. Slide the holder to the right so it snaps in place.c. Secure the holder with the provided screw.d. Insert the RJ-45 Connector into the RJ-45 Holder until it snaps into place.9. Mount the sub-base to the wall using included mounting screws and drywall anchors (if necessary). An optional mounting hole is available for more secure mounting, if needed. Make sure all wires extend through the hole in the sub-base see “Figure 4. Mount the Sub-base to the Wall”.4.4 Wiring1. Adjust the length and position of each wire to reach the proper terminal on the connector block of the sub-base. Strip 1/4” of insulation from each wire. Do not allow adjacent wires to short together when connected. 2. Match and connect control wires to the proper terminals on the connector block. Refer to Field Wiring Diagrams included in this document.3. Push excess wire back into the wall and seal the hole to prevent air leaks. NOTE: Air Leaks in the wall behind the Control can cause improper operation. 4. Attach the Control to the sub-base.5. Turn ON power to the heating and cooling equipment.RS1 RS1 ODT ODT W3 W2 W1 BK G Y2 Y1 O B/C RH RC AUX2 AUX1Mounting Holes Optional Mounting HoleWallThermostat WiringEthernetWiringThermostatWiresRJ-45PlugRS1 RS1 ODT ODT W3 W2 W1 BK G Y2 Y1 O B/C RH RC AUX2 AUX1Mounting Holes Optional Mounting HoleWallThermostat WiringEthernetWiringThermostatWiresRJ-45PlugFIGURE 2.

824 Programmable Comfort Control18-HD72D1-1 page 296. Basic Operation6.1 PI ControlThe 824 Control uses Trane’s proprietary control schemes to provide both comfort and energy efficiency. The Control samples the indoor temperature every five seconds and determines the capacity needed based on the following parameters:• Mode of operation• Proportional Error - distance from set point• Integral Error - Time away from set point6.2 Load ValueThe 824 uses Proportional Error plus Integral Error to determine the amount of capacity required. The calculated capacity is displayed as Load Value. Load Value is a numerical representation of the needed capacity to maintain the desired set point. The Load Value range is dependent on the applied system.72ºBCDSet PointTemperature2 SecondsIntegral ErrorRoomTemperatureAB + C + D... = Integral ErrorA = Proportional Error6.3 Duty CyclesIndoor temperature control is achieved by duty cycling the equipment when the load value is less than 100% of the current stage of operation. The duty cycle rate is dependent on the calculated load value.The duty cycle chart below indicates the number of cycles at 50% load (i.e. LV = 50).1 Hour6 CPH2 CPHAs with all PI-based controls the indoor temperature will fluctuate above and below the user selected set point to maintain comfort in the space. Adjusting the factory set CPH (Cycles per Hour) can affect how tight the control operates around the set point. The CPH can be adjusted in the Installer Settings>Advanced>Equipment (2 – 6 CPH) • Factory default for compressor operation is 3 CPH • Factory default for indoor heat is 5 CPHEffects of changing the cycle ratesLower CPH results in longer run cycles with less cycling but the indoor temperature may deviate above and below set point.Higher CPH results in highter indoor temperature control but shorter, more frequent cycles.6.4 Overshoot ClampThe 824 Control will enforce an “off cycle” anytime the control overshoots more than 2.5°F. Once the indoor temperature is within .75°F of set point an “on cycle” is allowed dependent on load value and minimum off times. Show illustration…6.5 Stage ThresholdsThe threshold to allow operation is a Load Value greater than 5 and operation is always terminated with a Load Value less than 1. Load Value also determines when additional stages of operation are requested. To prevent rapid cycling between stages, a stage threshold is enforced. The stage threshold is dependent on the applied system.LV=100LV=200 STAGE 3STAGE 1STAGE 2COMPRESSOR STAGING THRESHOLDS100-115100-115100-125100-125100-110100-110Y1 to Y2 - 100-110Y1 to Y2 - 100-110HP to W1 - 100-115HP to W1 - 100-115HP to Dual Fuel - 100-125HP to Dual Fuel - 100-125LV=100LV=200LV=300LV=400 STAGE 5STAGE 1STAGE 2 STAGE 3 STAGE 4AUX HEAT STAGING THRESHOLDS100-215100-215100-315100-315100-115100-115Compressor to W1 - 100-115Compressor to W1 - 100-115W1 to W2 - 100-215W1 to W2 - 100-215W2 to W3100-315W2 to W3100-315LV=100LV=200LV=300STAGE 4STAGE 1STAGE 2 STAGE 3FOSSIL HEAT STAGING THRESHOLDSW1 to W2 100-190W1 to W2 100-190W2 to W3 100-290W2 to W3 100-290100-125100-125Inhibit - Compressor to W1 - 100-125Inhibit - Compressor to W1 - 100-125
Installation Guidepage 30 18-HD72D1-1 6.6 Stage InhibitsWhen the stage threshold is exceeded, a stage inhibit is applied. The stage inhibit calculates the rate of recovery over a 10-minute period and determines if the next stage is required to meet the current demand. If the rate of recovery is great enough, then a new 10-minute inhibit is enabled. The Control will not go to the next stage of operation until it determines that the current stage cannot satisfy the current demand. Stage inhibits only apply between compressor stages and compressor heat to indoor heat. Stage inhibits do not apply to indoor heat stages.START INHIBIT10 MinutesY1 “ON” Y2 “ON” Y1 “ON”LV = 100LOAD VALUE (LV)LV = 110Stage Inhibits - Compressor StagingStage Inhibits - Compressor to Aux HeatSTART INHIBIT10 MinutesY1 “ON” W1 “ON” W1 “OFF”LV = 100LOAD VALUE (LV)LV = 115START INHIBIT10 MinutesY1 “ON” W1 “ON”Y1 “ON”45 SecondCool DownLV = 100LOAD VALUE (LV)LV = 125Stage Inhibits - Duel FuelStage inhibits can be disabled in the 824 Control Installer Settings>Advanced>Comfort.

824 Programmable Comfort Control18-HD72D1-1 page 317. Advanced Operation7.1 DehumidificationThe 824 utilizes the following methods for dehumidification:• Air flow reduction – If the indoor unit has a variable speed blower the 824 Control can reduce the system air flow by 30% anytime the indoor RH is higher than the cooling RH target. Air flow reduction is disallowed if the indoor temperature is more than 2°F away from the cooling set point. Dehumidification is enabled by default and can be disabled by navigating to Installer Settings>Advanced>Comfort settings.• “Fan Off” delays are defeated when dehumidification is enabled and the indoor RH exceeds the cooling RH target.• Cooling Overshoot - If cooling overshoot is enabled, the Control will allow a .1°F of overcooling for each 1% of RH error. When the system is actively overcooling, Dehumidification will be displayed on the 824 home screen. A maximum amount of overcooling can be configured for 1°F, 2°F or 3°F. Overcooling is enabled in Installer Settings>Advanced>Comfort settings.• Smart Continuous Fan – If this option is enabled, continuous fan operation will be interrupted when indoor RH exceeds desired cooling RH target. A humidity icon will be displayed along with the fan icon to indicate that continuous fan operation has been disabled due to high humidity conditions. Smart Continuous Fan will not interrupt the fan circulate mode. To enable this function press Menu>Fan>Smart Continuous Fan settings.7.2 Warm Air DischargeEnabling Warm Air Discharge will reduce the variable speed blower air flow by 20% when in compressor heating operation. Warm air discharge only applies to compressor heating and is disabled when hydronic, fossil fuel or electrical heat (including supplement heat) modes are activated. Warm Air Discharge can be enabled in Installer Settings>Advanced>Comfort settings.7.3 Lockouts7.4 Control Response Rate7.5 Aux Contacts The 824 has two sets of dry contacts which can be configured to control a Humidifier, Ventilation system or a Whole-House Dehumidifier.7.6 Stand Alone OperationDehumidifier can operate independent from cooling operation as long as the control is Cooling or Auto mode and the last call was cooling.If Stand Alone Operation is selected, the control allows the user to select whether the indoor fan operates with dehumidifier request.With Active Call for Cooling Only – Dehumidifier can only operate during an active call for cooling.

The amount of data logged will be dependent on the number of days logged and the storage capability of the USB Flash Drive. HOW TO END???8.3 DiagnosticsWithin the Diagnostic screen are two items related to alerts:• Current Alerts – Alerts which are currently active• Alert History – Alerts which have been cleared (last 30 days)NOTE: Each alert will have a date/timestamp of when the alert was negated.From both screens the user can select an alert code and get additional information on the alert as well as a list of possible causes, similar to the Interactive Troubleshooting Guide located on ComfortSite/ASDealernetAll alerts are categorized by severity:• CRITICAL — Loss of heating/cooling operation — Service call is required — Alert messages are displayed on the home screen and when closed, a flashing red icon is used to indicate alert condition.• MAJOR — Reduced functionality but basic/minimum operation is possible — Service call is not immediately required — Alert messages are not displayed on the home screen but a yellow icon is used to indicate alert condition.NOTE: Critical and Major alerts can be displayed on the home screen by pressing the alert icon on the shortcut toolbar (top right of home screen).• NORMAL — Functionality may be lost but should recover or information used for diagnostic purposes / performance monitoring — Service call is not required — Normal alerts are only displayed in the Diagnostic screen8.4 HistoryThe History screen allows the technician to view cycle count and run time data for each mode and stage of operation. This data provides a snap-shot in to how the system is operating. The technician can also compare the current month versus the previous month.
824 Programmable Comfort Control18-HD72D1-1 page 33Feature Description1-Touch PresetsThe 1-Touch Presets allows for an immediate change to the setpoint status. Set the desired temperature for the three status modes (Home, Away & Sleep). The control will remain in the selected mode until another mode is selected or the program reaches a new schedule period. Aggressive RecoveryAggressive Recovery: This option disables the 10 minute inhibit anytime the control sees more than a 2° change (such as moving from one program time frame to another). This applies to heating & cooling modes. Heating Aggressive Recovery: This option disables the 10 minute inhibit based on outdoor temperature in heating mode only. The value for outdoor temperature can be set from 0°–70°. Heating Aggressive Recovery can only be enabled if Aggressive Recovery is disabled. There is a 10 minute “inhibit” period between first and second stage compressor as well as compressor heating & auxiliary heating. This 10 minute inhibit period minimizes the cycling of higher capacity when the existing capacity is sufficient to meet the demand. Air Cleaner ModeThere are three options when setting the Air Cleaner Mode:Auto--the air cleaner will run whenever the blower is running.Quick Clean--the control will energize the air cleaner at 100% output and blower at 100% air flow for a 3-hour run cycle.Allergy Clean--the control will energize the air cleaner at 100% output and blower at 100% air flow for a 24-hour cycle.Alert IndicationSystem alerts will be indicated on the home screen of the control with two options: “Close” or “Dealer Contact Information”. • Selecting “Dealer Contact Information” will display the dealer screen. • Selecting the “Close” option will move the alert to the top right corner of the home screen. Pressing the icon button in the top right corner of the screen will recall the alert to the home screen.All alerts will remain until resolved.Critical Alert – indicates the loss of heating or cooling operation. Only critical alerts will be displayed on the home screen. These alerts will flash red when “closed” and moved to the top right corner of the control. Major Alerts – indicates the loss of system functionality, but the system is still operational. Major alerts will be displayed as a solid yellow icon in the upper right corner of the control. Blower On / Off Delays Blower on / off profiles can be set independently for heating and cooling modes. There are blower delays specific for variable speed, non variable speed and hydronic heat applications. CalibrationThe sensors (indoor, remote and outdoor) can be individually calibrated for temperature and humidity. The indoor sensors may be calibrated to plus or minus 5° or 5% in increments of 1 . The outdoor sensor may be calibrated to plus or minus 10° in 1° increments. Control Response Rate This feature changes the response rate of the control. Selecting a “faster” response rate will maintain a tighter tolerance of indoor temperatures, but increases the cycling of the system. Cycle RateThe cycle rate affects the cycle time of the system. With a 50% load value, a cycle rate of 3 will allow the system to run for 10 minutes and be off for 10 minutes; completing 3 cycles in one hour. A cycle rate of 5 would allow the system to cycle on and off at 6 minute intervals. The higher the cycle rate, the more often the system turns on and off. The actual amount of time the system will be “on” or “off” will be reflective in the load value of the home. Higher load value demands will increase system run time and decrease system off time. Lower load value demands will decrease system run time and increase system off time.Dealer InformationDealer contact information, including name, address, website and multiple phone numbers may be entered. In addition, a dealer logo (which must be named dealer.jpg) can be uploaded through the use of an SD card. File size should not exceed 3 MB. With software version 2.1 and above, a Dealer Code has been added. By simply typing in the dealer’s main phone number, all required fields will be auto-populated.
Installation Guidepage 34 18-HD72D1-1 Feature DescriptionDuty CycleWhen the control is requesting less capacity than the system can deliver, the control will duty cycle to meet the required demand. The length and frequency of each duty cycle is based on the cycle rate and current load value.DehumidificationThere are two requirements before dehumidification is enabled:• Dehumidification must be enabled through the Installer Setup.• The indoor relative humidity must be above the desired setpoint.The system will take the following actions once this condition is met:• The blower will reduce air flow proportional to the amount of RH error. The control evaluates the percentage of humidity error and how long the error has existed to determine the amount of air flow reduction, up to 30% reduction.• If overcooling is enabled, the control will engage a 1 degree of overcooling for each 10% of RH error. A maximum amount of overcooling can be configured to 1, 2 or 3 degrees. • Fan off delays will be eliminated.Smart Continuous FanContinuous fan operation will be interrupted when indoor relative humidity exceeds desired humidity setpoint. A humidity icon will be displayed along with the fan icon to indicate that blower on options have been disabled due to high humidity conditions. Smart Continuous Fan will not interrupt the fan circulate mode.Alert Code DiagnosticsDiagnostics are displayed as current alerts (what is currently happening in the system) and alert history (what has occurred in the past, but are no longer present). The alert screen describes the alert, when the alert happened, the severity level of the alert as well as a problem description and possible causes to assist with troubleshooting. Up to the last 30 days are displayed.Dual Fuel OptionsThe change over from heat pump to furnace can be set based on three options:• Comfort–This is strictly based on indoor temperature demand. The furnace will take over when the heat pump can no longer maintain the indoor heating demand.• Operating Cost–The HSPF of the heat pump and AFUE of the furnace must be entered along with cost of electricity and fuel. The control calculates an economic balance point for system change over.• Outdoor Temperature–The changeover from heat pump to furnace is based on outdoor temperature which can be set from 0–70° (thermal balance point).The furnace will take over anytime the HP is unable to maintain indoor temperature, regardless of the dual fuel option chosen. Emergency Heat The heat pump will be disabled and the furnace / heat strips are enabled any time the control is set to Emergency Heat. Fan OptionsThere are three options available for blower operation:• Auto–the blower runs when there is a call for cooling or heating. • On–the blower will run continually with a fan only call. The continuous fan speed for variable speed motors can be adjusted from 35%–100%. A call for heating or cooling will supersede a fan only call and the blower will run at a speed that matches the staging of the equipment. • Circulate–this provides all the features of “fan on”, but the blower will only run a percentage of the time when there is no call for heating or cooling. The blower can be set to circulate from 10–55 minutes of every hour. History ScreenThe History Screen provides system cycle information. Cycle counts and run time can be viewed for first stage and second stage compressor operation, W1, W2 & W3 heating and defrost cycles. This information can be viewed in a 24 hour, 1 week or 1 month period.
824 Programmable Comfort Control18-HD72D1-1 page 35Feature DescriptionHumidificationThere are two options available for humidification: • Indoor RH setpoint—this controls the humidifier based on the desired indoor humidity setpoint (options from 10%–45%). • Frost Control setpoint--The control references the outdoor temperature and indoor environment to calculate the risk of frost or condensation on interior walls and windows. A scale of 0 to 10 allows for customized settings based on the insulation properties of the home. A higher number may be selected for well insulated homes, whereas a lower number should be selected on poorly insulated homes. A lower number should be utilized if condensation is observed. There are two control options for enabling humidification:• Humidification with an active call for heat.• Humidification without an active call for heat (control energizes blower and humidifier). • Blower speed can be adjusted when there is no active call for heat but a call for humidification is presentHumidification is only available when in the heating mode (or in the auto mode when the last call was for heating). A 60 second minimum blower off delay is enforced if “steam” humidification is selected.Installer SetupThere are two categories for Installer Setup.• Standard—this is the basic system settings such as heat pump or cooling only, single or multi stage, compressor type, etc. This is the basic system set up that is self discovered in communicating mode, but requires manual input when using a Relay Panel for 24 volt configurations.• Advanced—this provides advanced configuration of the system such as cycles per hour, minimum run times, humidification and dehumidification setpoints, blower delays and temperature lockouts to name a few of the customizable features in this set up. Load ValueLoad Value is a numerical representation of the needed capacity to satisfy the setpoint. Proportional (distance from setpoint) error plus integral (time away from setpoint) error is used to calculate load value.LockoutsSystem lockouts will disable a certain function of the system under specific outdoor temperatures:• Compressor Heating Lockout – will lockout all compressor operation below a set outdoor temperature (from 5°–70°). This value must be set lower than the auxiliary heat lockout. • Auxiliary Heating Lockout – will lock out auxiliary heat stages above a set outdoor temperature (from 40°–70°). This value must be set higher than the compressor heating lockout.• Defrost Heater Balance Point for W1, W2 & W3 – will lock out specific auxiliary heat stages when above a set outdoor temperature. (W1 setpoint is from 40°–55°, W2 & W3 setpoints are from 5°–55°). This feature does not apply to dual fuel systems. • Compressor Cooling First Stage Lockout – will lock out the first stage compressor above a set outdoor temperature. (from 80°–120°)• Compressor Heating First Stage Lockout – will lock out the first stage compressor below a set outdoor temperature. (from 0°–50°)• Furnace First Stage Heating Lockout – will lock out first stage furnace operation below a set outdoor temperature. (from 15°–50°)First stage lockouts are not available with zoning.Reminder Screens Reminders can be set for filters, UV lamps, humidifier pads, and various other service reminders. RestoreThere are three levels of restore:• Restore from the Setting Screen – this restores all personal configurations, such as program schedules and home screen customization to their default setting. • Reset Advanced Options from the Install Set Up screen – this restores all the advanced set up selections such as system lockouts, accessories, air flow and comfort options to their default setting.• Restore Factory Defaults – this restores the control to its “out of the box” condition. All settings will be set to their factory default condition.
Installation Guidepage 36 18-HD72D1-1 Feature DescriptionSecuritySecurity initiates a keypad lockout. The control can only be accessed by a four digit pass code which can be configured in two different formats:Pin Lock: When the Pin Lock is selected, the control is completely locked. The user will need to enter a four digit password to change any setting (the default is “1234”).Guest mode: The enabling of this mode allows a guest to change the temperature up to 5° in either direction from setpoint and access to the weather, but cannot change the mode or any customized settings. Note: The back door password is 9467.Network Diagnostics Screen gives the user the ability to view the wireless connectivity of the 950 Control. Save Diagnostic Logs is used to record wireless data for troubleshooting purposesSetpoint Dead Band This sets the temperature band between heating and cooling setpoints while in the auto mode.Software UpdatesThe control is field software upgradable. The software can be upgraded by two methods:USB Flash Drive upgrade - Insert a USB Flash Drive with new software loaded and use the software upgrade screen to complete the upgrade process.Internet upgrade - Use the software upgrade screen to complete the upgrade processSystem Report The System Report Screen provides a real time in depth look at operating conditions. While similar to the System Status screen, the system report adds additional information for service technicians. Test ModeThere are three Test Modes in the control:System Test - Ability to test heating/cooling/blower/humidifier and aux contacts for up to 30 minutes.Damper Test - Ability to test damper operation (see Zone Panel IG for more information).Variable Speed Test - Technician Access ScreensThe “Technician Access” icon has a 5 second hold delay to enter the technician service screens. After this 5 second hold delay, the technician will see a “Caution!” screen noting that only a trained HVAC technician should proceed into this area. VentilationThe 950 control has the ability to control a ventilation system through the AUX contacts of a Relay Panel (Model BAY24VRPAC52DB* or newer). This function is enabled in the Installer Setup > Advanced > Accessories > Ventilation Installed. Once enabled the minimum ventilation can be set for each hour. Ventilation can be overridden during extreme temperature conditions by setting a maximum and minimum outdoor temperature for ventilation operation (wired outdoor sensor must be connected and enabled). Additional options are available to accumulate overridden runtime. All options are available for selection in Installer Setup > Advanced > Accessories section. Note: Currently there is no option to interlock the blower with a call for ventilation.Warm Air DischargeEnabling Warm Air Discharge will reduce the variable speed blower air flow by 20% when in compressor heating operation. Warm air discharge only applies to compressor heating and is disabled when hydronic, fossil fuel or electrical heat (including supplement heat) modes are activated.Whole House DehumidifierThe 950 control has the ability to control a whole-house dehumidifier through the AUX contacts of a Relay Panel (Model BAY24VRPAC52DB* or newer). This function is enabled in the Installer Setup > Advanced > Accessories > Dehumidifier Installed. The dehumidifier can be setup for stand-alone operation or only when the system is actively cooling. The user can also select whether the blower will be energized with a call for dehumidifier operation. Dehumidifier operation is only allowed in Cooling Mode or in Auto Mode when the last call for operation was cooling.
