when you manually raise the setting and want to allow the thermostat to stage based on recent system performance.

The Fast Cool feature operates the cooling stages in the same manner as Fast Heat, On or Off when the tempera- ture is lowered below the room setting.

27.Select Remote Temperature Sensor – Allows one wired remote temperature sensor (indoor, F145-1328, or outdoor, F145-1378) be connected to it and indicates the measured temperature in clock digits. This item allows you to select the remote sensor and also configure it as indoor or outdoor temperature sensor. Factory default is off. Select Remote On and Remote in (for indoor) or Outdoor Remote.

Local Temperature Sensor disable – This is applicable only when indoor remote temperature sensor is enabled.

Factory default is On LS. You can make it Off LS if de- sired by using or touch keys. Then, only the indoor remote temperature reading will be used for control.

28.Select Dual Fuel Feature With No Outdoor Sensor (dF) – This feature is applicable only in heat pump modes and with no outdoor sensor. When selected ON, the thermostat will use software logic to determine when to switch to gas heat and shut down the compressor.

Select DF setting (dF) – With DF selected On and no outdoor sensor, select the dF setting from 01-09. Fac- tory default is 05. The dF setting influences when second stage comes on. The factory default creates a separation of approximately 1oF between stages. Increasing the set- ting decreases the separation between stages. Decreas- ing the value increases stage separation. This adjust- ment allows a small change in the operation of your heat pump system versus your auxiliary system relative to the thermostat adjustment. The higher the number the sooner the auxiliary stage energizes. The lower the number the longer period of time before auxiliary is energized.

Note: This setting is not minutes or degrees. It is numeric setting that will influence the internal thermostat calcula- tion for staging.

Select Compressor Delay (Cd) – After the auxiliary heat is turned on, the compressor(s) shut down is delayed for the time selected (in seconds). This delay is factory set to 60, but can be set in the range of 0 to 99.

29.Select Dual Fuel Feature Using Outdoor Sensor (dF)

– This feature is applicable only in heat pump modes and with an outdoor sensor installed and enabled in step 27. When selected ON, the thermostat will use the outdoor sensor temperature to determine when to switch to gas heat and shut down the compressor.

Select DF setting (dF) – With DF selected ON, select the setting for outdoor temperature. When the outdoor tem- perature goes below the selected temperature, the gas heat will begin. Default is 35°, but can be set in the range of 5° to 50°.

Select Compressor Delay (Cd) – After the auxiliary heat is turned on, the compressor(s) shut down is delayed for the time selected (in seconds). This delay is factory set to 60, but can be set in the range of 0 to 99.

30.Select Auxiliary Off (AO) – Select the temperature that will inhibit the auxiliary heating stage. As long as the out- door temperature is above the selected temperature, the auxiliary heat will not turn on. The default setting is 60°, but can be set in the range of 35 ° to 80°.

31.Select Programmable Blower Balance Point (bP) – Re- quires DHM connection from thermostat to heat pump system. This feature de-energizes the DHM terminal to operate the blower at a slower speed for first stage heat when the outdoor temperature is below the temperature selected. This circulates warmer air than the higher fan speed. The default is 80o (disabled), but can be set from 20o to 79o. Select an outdoor temperature where the air coming out of the ducts begins to feel cool and the ther- mostat will lower the fan speed to circulate warmer air.

32.Humidity Display (Hd) – Selecting HD On enables the display to alternately show the current time and the hu- midity. If HD is selected OFF, the display will not show the humidity.

33.Adjustable Humidity Display – The display will show the ambient humidity and 00 (default). The setting can be changed from -20 and LO to 20 and HI. The displayed humidity will change as the offset is changed. In Run mode, the displayed humidity will be the ambient humidity adjusted by the setting selected.

34.Auto Humidity Reduction (HR) – This feature au- tomatically lowers humidity setting when the outside temperature drops to prevent the interior windows/walls from reaching the dew point where water condenses on surfaces. This feature default is OFF. It can be changed to select LO (low humidity reduction) or HI. To achieve automatic humidity reduction, the thermostat lowers the humidity when furnace cycles are long. When the outside temperature rises, it increases humidity. "LO" indicates a low amount of humidity reduction.

35.Automatic Humidification (AH) – This feature if enabled allows for humidification independent of a call for heating

– useful in arid climates where addition humidification in heating and/or cooling is desired. If enabled, will energize the humidifier and circulator blower (“G” terminal and the

“HM” terminal) if the actual humidity is below the humid- ity set point. The display indicates AH. Pressing the key will cycle the display from OFF to H (feature enabled in Heat mode) to C (feature enabled in Cool mode) to A (feature enabled to Auto mode) and back to OFF.

36.Cycle Humidifier (CH) – This feature provides an op- tion that reduces the water usage by up to 50% when a flow-through humidifier is controlled by the thermostat. It is recommended for use on flow-through humidifiers only.

The display indicates CH (Cycle Humidifier) with the de- fault indicating OFF. Pressing theorkeys will toggle the display from OFF to On and back to OFF. When CH is enabled, the humidifier will cycle to turn off for 10 minutes after it has run for 10 minutes. The blower and/or furnace will continue to run during the humidifier off period.

37.Programmable Dehumidification Optimal Comfort Mode (OC) or Optimal Dehumidification (Od) – This item can be selected to OC (Optimal Comfort mode), Od (Optimal Dehumidification), or OFF. When Optimal Com- fort (OC) is enabled, this feature automatically reduces indoor humidity with a call for Cooling if humidity is 2% above humidity setpoint. Humidity is set by pressing the

Humidity key when in the appropriate mode, in this case Cooling, and pressing theorkeys to set desired humidity (range 40% to 95%) level followed by pressing Humidity key again. This dehumidification feature uses less energy by maintaining temperature and dehumidify- ing only when a call for Cooling is required. Optimal De- humidification (Od) when enabled, this feature automati-
