Mounting Optional Accessories Installing RedLINK indoor sensors

A wireless sensor is included with the THX321WFS2001W thermostat. The C7189R2002-2 indoor sensor 2 pack can be ordered separate. These sensors detect Temperature, humidity and motion.

Up to 20 of these optional indoor sensors can be used with the T10 thermostat. These sensors can be used to sense

temperature from a different location than the thermostat, average temperature from multiple locations, or control the temperature based on sensor priority (through scheduling, manually selecting priority sensors, or prioritizing active rooms.

The T10 can prioritize active rooms using the motion detectors in the indoor sensors.

CAUTION Electrical Interference (Noise) Hazard. Can cause erratic system operation. Keep wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts and large power distribution panels. Use shielded cable to reduce interference when rerouting is not possible.

IMPORTANT Erratic temperature readings from a sensor can occur as a result of any of the wiring practices described below. Avoid these practices to assure correct operation. Use shielded cable to reduce interference if rerouting of sensor wiring is not possible.

— Be sure wires have a cable separate from the thermostat cable.

— Do not route temperature sensor wiring with building power wiring, next to control contactors or near light dimming circuits, electric motors or welding equipment.

— Avoid poor wiring connections.

— Avoid intermittent or missing building earth ground.

The thermostat reads the indoor humidity level and allows the user to set a humidification setting with or without window protection. The thermostat can be set up to control a humidifier in any system mode in the Installer Setup (ISU 8060).

Window Protection

Window Protection limits the amount of humidity to prevent frost or condensation on windows. Window Protection (ISU 8050) requires either an outdoor sensor or use of Internet weather (Outdoor temperature setting In ISU chart on page 17. The thermostat prevents frost or condensation on windows by not allowing the humidifier to run above a certain level. To prevent frost or condensation, the thermostat may turn off the humidifier before the humidity setting is reached. If Window protection is enabled ((ISU 8050), you can adjust this setting by pressing MENU, then scroll down and select Humidification-Options-Window Protection Level. Window Protection is set on a scale from 1-10. A setting of "1" represents poorly insulated windows and a setting of "10" represents well insulated windows. A lower number automatically reduces the humidity to help prevent frost or condensation on your windows. Use a higher number if indoor air seems too dry. To prevent frost/condensation on your windows during cold outdoor temperatures, poorly insulated windows require a lower Window Protection setting, which will limit how much your humidifier can run. After you set the Window Protection setting, check for frost/condensation on your windows in the morning. If frost/condensation is present, adjust the Window Protection setting to the next lowest number and check for frost/condensation on your windows the next morning. Continue to adjust the Window Protection setting to a lower number until frost/condensation is no longer present If Window Protection is turned Off, the thermostat controls the humidity level to the user's desired humidity setting. Frost or condensation may appear on windows.

Set up Humidification

— The thermostat turns on the humidifier only if the heat is currently running and humidification is needed.

— The thermostat turns on the humidifier only if the fan is currently running and humidification is needed.

— The thermostat turns on the humidifier and the fan when humidification is needed.

— The thermostat turns on the humidifier when humidification is needed and the humidifier controls the fan.

Control Humidification Level

Window Protection is set on a scale from 1–10. A setting of 1 represents poorly insulated windows and a setting of 10 represents well insulated windows. A lower number automatically reduces the humidity to help prevent frost or condensation on your windows. Use a higher number if indoor air seems too dry. To prevent frost/condensation on your windows during cold outdoor temperatures, poorly insulated windows require a lower Window Protection setting, which will limit how much your humidifier can run.

NOTE: The Window Protection option is only available if a wired outdoor sensor or Internet is used to provide outdoor temperature. See ISU setting “Outdoor Temperature” on page 17.

Dehumidification

The thermostat reads the indoor humidity level and allows the user to set a dehumidification setting. The thermostat controls the humidity level using the cooling system or a whole house dehumidifier.

Dehumidification using the Cooling System

When set for A/C with Low Speed Fan or A/C with High Speed Fan, an overcooling limit can be set from 0 °F to 3 °F (ISU 9070). The thermostat uses the cooling system to reduce humidity by lowering the temperature up to 3° F below the current cool setpoint until the desired humidity level is reached. If set for A/C with Low Speed Fan, configure U contacts as normally open or normally closed (ISU 9050) and wire to the Low Speed Fan terminal on the equipment. For example, if the U contacts are normally closed, they will open when the thermostat calls for dehumidification. See “Whole House humidifier, dehumidifier, or ventilator wiring” Fig. 27 to Fig. 30.

If humidification and dehumidification are both setup to operate in the system mode (Off), the thermostat will automatically enforce a 15% deadband between the humidification and dehumidification settings. The thermostat will automatically switch between humidification and dehumidification to maintain the desired humidity level.

Dehumidification using A/C with Low Speed Fan, A/C with High Speed Fan, has the following methods of dehumidification control (ISU 9080):

Dehumidification overcooling limit (ISU 9070): This option uses the cooling system to lower the temperature up to 5° F below the current cool setpoint until the desired humidity is reached. The Dehum Over Cooling Limit range is from 1° to 5° F.

NOTE: The thermostat will not lower the fan speed when the second stage of cooling is on.

Set up Dehumidification With Cooling System Some screens shown in this section may not appear on the thermostat, depending on how you set up dehumidification.

Dehumidification using a Whole House Dehumidifier

The Whole House Dehumidifier option requires a dedicated unit for dehumidification. The thermostat can be set to control dehumidification in all modes (Heat, Off, Cool [ISU 9120]). Set up Dehumidification With Whole House Dehumidifier (Some screens shown in this section may not appear on the thermostat, depending on how you set up dehumidification.)

NOTE: Heat includes Heat, Emergency Heat and Auto. If the system is in Auto mode, the thermostat will allow dehumidification if the last call was for heat.

Cool includes Cool and Auto. If the system is in Auto mode, the thermostat will allow dehumidification if the last call was for cool.

page 26.

page 26.

Control Dehumidification Level

NOTE: If your air conditioner is used to control humidity, the temperature may drop up to 3° F below your temperature setting until humidity reaches the desired level.

NOTE: If humidification and dehumidification are setup to operate in the same system mode (Off) the thermostat will automatically enforce a 15% deadband between the humidification and dehumidification settings. The thermostat will automatically switch between humidification and dehumidification to maintain the desired humidity level.

Dehumidification using the Cooling System

Dehumidification using A/C with Low Speed Fan, A/C with High Speed Fan, has the following methods of dehumidification control (ISU 9080):

Cooling Droop (ISU 9080): This option uses the cooling system to lower the temperature up to 3° F below the current cool setpoint until the desired humidity is reached. The Dehum Over Cooling Limit range is from 0° to 3° F for dehum with low speed fan or 1° to 3° F for dehum with high speed fan.

Ventilation

The thermostat can be set for the following ventilation types: (ISU 10000)

Ventilation Control Methods (ISU 10050) Ventilation can be setup to meet either ASHRAE or Percent On Time settings. To meet these settings, the thermostat will ventilate during calls for heat, cool, and fan. If the required ventilation has not been achieved for ASHRAE or Percent On Time, the thermostat will force the ventilation equipment on.

ASHRAE The thermostat operates ventilation equipment to meet the ASHRAE 62.2 ventilation standard based on CFM, number of bedrooms, and square footage of the house. ASHRAE 62.2 can only be met if the ventilation equipment is running. If the ventilation equipment is off for any reason (outdoor ventilation lockouts, set up to turn Off during Sleep period, turned off by user, etc.), ASHRAE 62.2 is not met during those times. See ISU 1012 to select a Ventilation Priority.

Percent On Time The thermostat operates ventilation equipment based on a percentage entered in the installer setup (ISU 1012). For example if Percent On Time is set to 50%, the ventilation equipment will run at random times during a 1 hour period until it reaches a 50% run time (approximately 30 minutes). Default setting is 30%. Range is 10% to 100% in 10% increments.

Ventilation Fan Control (ISU 10060)

— The thermostat turns on the ventilator and the fan when ventilation is needed.

— The thermostat turns on the ventilator when ventilation is needed. The fan is controlled by the equipment.

Ventilation Priority (ISU 10125) Lockouts are Priority The thermostat places a priority on lockouts versus the ASHRAE 62.2 ventilation standard. The thermostat will not run ventilation during the following lockout conditions (if configured) unless you manually call for ventilation:

— Lockout Ventilation during Outdoor Conditions (ISU 10130)

— Lockout Ventilation during “Sleep” program periods. Note: This option is set by the user on the Ventilation screen. From Home press menu-ventilationoptions-disable during sleep.

ASHRAE is Priority ASHRAE requires additional ventilation following a long off cycle. The thermostat meets the ASHRAE 62.2 ventilation standard by running additional ventilation when outdoor conditions are favorable. If ASHRAE cannot be met when outdoor conditions are favorable, the thermostat will override the outdoor lockouts and run ventilation. When using this option, it is recommended to increase the rate (CFM) of the ventilation equipment to meet the ASHRAE 62.2 ventilation standard in a shorter run time.

NOTE: The ability to lockout ventilation during the “Sleep” program periods is not an option when you select ASHRAE is Priority.

Ventilation — Outdoor Condition Lockouts (ISU 10130) Ventilation will not operate when outdoor conditions exceed the lockout settings unless you manually call for ventilation or Ventilation Priority (ISU 10125) is set to ASHRAE is Priority and ventilation is needed to meet ASHRAE. Lockouts can prevent ventilation during extreme weather conditions to keep humid, hot, and cold air out of the home.

NOTE: This feature requires a wired sensor for outdoor temperature limits, or Internet connection for temperature and humidity lockouts.

Options are:

Auto Changeover operation

Auto changeover is available if the thermostat is configured for at least 1 heat stage and 1 cool stage and ISU 3000 is set to “Auto”.

When configured this way, you can select “Auto” as one of the options under “System mode”.

ISU 3015 is the auto changeover differential setting. It can be set from 0-3 °F. (0-2.5 °C) to This is the minimum number of degrees needed between the heat and the cool setpoints when the thermostat is in auto changeover mode. When in auto mode, the customer can always set the heat and cool setpoint to the same temperature, regardless of the differential setting although most customer prefer to have a cool setpoint that is at least 3 degrees above the heat setpoint. When 0 is selected, we enforce a 1.5°F differential behind the scenes to ensure the heat doesn’t come on after cooling shuts off or vice-versa.

The differential is the minimum number of degrees the temperature needs to rise or fall before switching from heat to cool while in auto changeover mode. Example: If heat and cool were both set for 70, and heat had been used last, the temperature would need to rise at least 3 degrees above the heat setpoint before the thermostat would turn on cooling. Then it would cycle cooling on and off to maintain setpoint and the temp would need to drop at least

If the AC is used for dehumidification then we enforce an additional temp drop below the overcooling amount, (ISU

9070) prior to switching back to heat. Em Heat and auxiliary heat operation Auxiliary heat:

Emergency heat: Emergency heat runs when you manually switch the thermostat to the em heat mode. When the thermostat is in emergency heat mode, the heat pump is locked out.

Emergency heat mode is only available when the thermostat is configured for a heat pump (ISU 2000) and Backup heat stages is set to 1 (ISU 2071).

From home screen touch the menu icon and then “system Mode”. You can set the thermostat to heat, off, cool, emergency heat, or auto (auto only available if ISU 3000 is set to auto).

When the thermostat is set to em heat mode, the heat pump is locked out and the backup heat is used to maintain the heat setpoint.

If ISU 2175 is set to “Drive aux and E together”, then with a call for emergency heat or auxiliary heat, both E and AUX terminals are energized. Typically the backup heat is wired to Aux and E is unused when set this way.

If ISU 2175 is set to “Aux and E independent”, then with a call for emergency heat, the E terminal is energized and the aux terminal is not. The wire to Aux controls a heat source that runs as backup heat to the heat pump when the mode is set to “heat”. The wire to E controls a heat source that runs independent of the heatpump when mode is set to em heat. In most cases, the heat pump uses the same heat source for auxiliary heat and em heat.

Dual fuel systems (Heat pump with gas or oil furnace backup) cannot run the heat pump and furnace at the same time.

Advanced Features Adaptive Intelligent Recovery Over time, the T10 thermostat "learns" how long it takes your system to reach your programmed temperature setting.

The thermostat turns on the heating/cooling system early and assures that the programmed temperature setting is reached at the programmed time regardless of weather conditions. For example, if the Wake program period is set to 6:00 am with a heat setting of 70 degrees, the heat will turn on before 6:00 am, so the temperature is 70 degrees at 6:00 am. The thermostat displays "In Recovery" when it turns the system on early.

Adaptive Intelligent Recovery® calculates the recovery ramp based on how far the room temperature is away from the temperature setting, previous equipment performance and weather history, allowing the thermostat to start recovery at the optimal time so it can reach the programmed temperature setting at the programmed time. The T10 thermostat uses two recovery ramps when setup to control a heat pump system. One ramp for the compressor and one ramp for the auxiliary heat. Once the room temperature intersects the compressor ramp, the compressor turns on until the setpoint is reached. If the room temperature does not rise quickly enough and intersects the second ramp, the auxiliary heat turns on. It takes about one week for the thermostat to adjust to weather conditions, equipment performance and construction of the home. If the temperature setting is reached too early or too late, the ramp is adjusted for the next day's recovery. See Fig. 48.

Compressor Protection The thermostat keeps the compressor off for a few minutes before restarting, to prevent equipment damage. During this "off" time, the message "Wait" is displayed on screen.

P + I Control A conventional mechanical or electronic thermostat does not control temperature precisely at setpoint. Typically there is an offset (droop) in the control point as the system load changes. Many factors contribute to offset including the switch differential, thermal lag, overshoot, cycle rates and system load.

The T10 thermostat however, works much differently than a conventional mechanical or electronic Thermostat when droop is set to comfort. Droop is always set to comfort and not adjustable when controlling a 2 stage furnace or 2 stage heat pump without aux heat. The proprietary algorithm in the thermostat eliminates the factors causing offset (droop). This makes temperature control more accurate than the conventional mechanical or electronic thermostat. The temperature control algorithm is called proportional plus integral (P + I) control.

The thermostat sensor or indoor sensor senses the current space temperature. The proportional error is calculated by comparing the sensed temperature to the setpoint temperature. The deviation from the setpoint is the proportional error.

The thermostat also determines integral error, which is a deviation based on the length of error time (how long the sensed room temperature has been away from the setpoint temperature). The sum of the two errors is the (P + I) error.

The cycle rate used to reach and maintain the setpoint temperature is computed using the P + I control algorithm. The addition of the integral error is what differentiates the thermostat from many other mechanical and electronic thermostats.

Heat Differential

For stage 2 of conventional systems or 2 stage heatpump without aux heat The thermostat will use the stage of heating as needed to keep the indoor temperature within 1 °F (0.5 °C) degree of the setpoint. The thermostat turns on stage 2 when the capacity on stage 1 reaches 90%.

Heat pumps with electric aux heat when droop is set to “comfort” The thermostat will use the stage of heating as needed to keep the indoor temperature within 1 °F (0.5 °C) degree of the setpoint. The thermostat turns on Aux heat when the capacity on highest compressor stage has reaches 90%.

Heat pumps with electric aux heat when droop is set to 2°F or higher (2 °F to 15 °F adjustable) If the indoor temperature drops to the droop amount while the highest compressor stage is running the thermostat will continue to run the heatpump stages and also energize the Aux heat.

For example, if the Backup Heat Droop is set to 2 °F (1.0 °C), the indoor temperature must drop 2 °F (1.0 °C) below the setpoint while the previous stage is running before the backup heat turns on. Raising setpoint manually or by a schedule change does not cause droop to run the backup heat. When droop is set to other than comfort, the upstage timer setting is also available.

Dual fuel Heat pumps with gas or oil backup heat

If thermostat is configured to control dual fuel, the droop cannot be set to comfort. It will default to 2 °F and can be adjusted from 2 °F to 15 °F.

If the indoor temperature drops to the droop amount while the highest compressor stage is running the thermostat will end the call for the heatpump stages and run the fossil fuel heat stage.

For example, if the Backup Heat Droop is set to 2 °F (1.0 °C), the indoor temperature must drop 2 °F (1.0 °C) below the setpoint while highest heatpump stage is running before the thermostat will shut down the heat pump and run the fossil fuel heat.

Raising setpoint manually or by a schedule change does not cause droop to run the backup heat. When droop is set to other than comfort, the upstage timer setting is also available.

Upstage Timer The upstage timer setting is only available when: The thermostat is configured for a heat pump with an aux heat stage (electric of fossil fuel). The droop setting is set to a setting other than “Comfort” (2 °F to 15 °F). Backup Heat Upstage Timer options are Off, 30 minutes to 16 hours. Default is Off. The upstage timer allows* the aux heat to run when the highest heat pump stage has run for longer than the timer setting during a steady state condition. Steady state means the thermostat is cycling to maintain setpoint. Manually raising the setpoint or a scheduled setpoint change will not trigger the upstage timer. In those conditions the thermostat will not use backup heat unless a different condition triggers the thermostat to run the backup heat (Droop, balance point, or manually switching the thermostat to em heat mode).

*Droop and upstage timer are designed to restrict the auxiliary heat for customers who are energy conscious. The aux heat does not necessarilly run after the timer has expired even in a steady state condition. Once the timer expires in steady state the thermostat calculates whether or not to run the aux heat based on the load capacity of the highest heat pump stage.

If the heat pump struggles to maintain setpoint, we would suggest one of the following steps:

PROGRAMMED RECOVERY If the primary heat is making progress as expected, backup heat will not be used to reach the setpoint of the next program period. Backup heat is always restricted during a programmed recovery when the Adaptive Intelligent Recovery feature is used. See note below.

NOTE: During a programmed recovery (or when the temperature setpoint is changed by the user), the thermostat waits to turn on the backup heat depending on system performance, load conditions and how many degrees the temperature setpoint is changed. Backup heat will be used ONLY when the temperature is not rising quickly enough to reach the setpoint in a reasonable time. Upstage timer for heat pump with aux heat applications is only used in steady state (cycling to maintain setpoint). The thermostat will not run the aux heat during a programmed recovery unless one of the following conditions occurs:

Finish with high Heat stage and/or Finish with high cool

stage These settings allow the installer to keep the high stage of the equipment running until the desired setpoint is reached. This setting is recommended for Geothermal Heat Pumps to allow the loop to rest.

When set to no (default), the thermostat cycles the stages based on load conditions and the cycle rate setting for these stages.

“Finish with High cool Stage” is ISU 3020 “Finish with High stage Stage,” is ISU 3021. Set to Yes to turn on these features. Default is No. See ISU settings on page 19.

HEAT PUMP AND BACKUP HEAT OPERATION Heat pump with outdoor temperature lockouts Outdoor temperature lockouts are optional. See Installer Setup options (ISU 312).
