 Select Fast Second Stage, ON or OFF – 

Not    

available if configured for SS1. Selecting FA ON forces 
additional heat stages to come on quickly when 

 is 

used to raise the temperature a few degrees above the 
room. Select this setting if you want the heat to increase 
quickly when you manually raise the temperature.

 

Selecting FA OFF allows the thermostat to calculate an 
optimal time to bring on additional stages of heat. When 
the 

 is used to raise the setting above the room tem-

perature additional heat stages may come on very quickly 
or very slowly (up to 30 minutes later) depending on 
recent system performance. Select this setting if you do 
not require the additional heat stages to come on quickly 
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.

30. 

Select Remote Temperature Sensor

 

Enabled 

– ON 

enables a remote sensor connected to thermostat and dis-
plays the sensor temperature in the clock digits. OFF (de-
fault) indicates no remote sensor connected or enabled.

31. 

Select Remote Sensor as Indoor or Outdoor

 – If 30 

is enabled, select the remote to be 

Remote In

 (Indoor, 

F145-1328) or 

Outdoor Remote

 (Outdoor, F145-1378). 

Default is 

Remote In

.

32. 

Select Local Sensor Disable

 – If 31 is selected Indoor, 

the thermostat Local Sensor can be disabled so the 
displayed temperature will be from the Remote Sensor. 
Default is 

On LS

. To disable the Local Sensor, change 

selection to 

OFF LS

.

 

33. 

Select Dual Fuel Feature (dF

) – This feature is appli-

cable only in heat pump modes (HP1, HP2). Enables (On) 
or disables (Off) dual fuel feature of thermostat.

34. 

Select Dual Fuel Temperature 

– With dF selected On 

and outdoor remote sensor available, select the outdoor 
temperature the thermostat will use to determine when to 
switch to gas heat and shut down the compressor. When 
the outdoor temperature falls below the selected tem-
perature the gas heat will begin. Default is 35°, but can be 
set in the range of -5 to 50°. A lower setting will delay the 
start of gas heat allowing cooler temperature in the home.

 

 INSTALLER/CONFIGURATION MENU 

35. 

Select Dual Fuel Setting

 – 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 1

°

F 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 for better comfort. The lower 
the number the longer period of time before auxiliary is 
energized for more economy.

Note

: This setting is not minutes or degrees. It is numeric set-

ting that will influence the internal thermostat calculation 
for staging.

36.  

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. 

37. 

Select Auxiliary Off (AO)

 – Applicable with HP1 or HP2 

selected with outdoor sensor. Select the temperature 
that will inhibit the auxiliary heating stage. As long as the 
outdoor temperature is above the selected temperature, 
the auxiliary heat will not turn on. The default setting is 
80°(disabled), but can be set in the range of -5

 

° to 79°. 

Thermostat will not allow a setting at or below the (dF) 
dual fuel setting.

 

If indoor temperature drops below 45° because of a pos-
sible heat pump malfunction, the thermostat will turn off 
the pump and switch to Auxiliary heat. "Call for Service" 
will display on screen.

 

There are two ways the thermostat will return to normal 
heat pump operation:

•  Press any key to retry the pump and erase the "call for 

service icon.

•  When setpoint is achieved on Auxiliary, system will 

return to heat pump operation on next call for heat.

stat to display the words 

"Change UV Lamp"

Service of UV bulb) after a set time of UV bulb operation. 
This is a reminder to maintain your UV system at opti-
mum level of operation. When enabled, the factory set 
interval for 

"Change UV Lamp"

 to be displayed is 350 

days of UV bulb operation and can be adjusted in 25 day 
increments. This should be adjusted with respect to the 
bulb’s recommended maintenance schedule.

 after a set 

time of blower operation. This is a reminder to change 
or clean your air filter. This time can be set from 25 to 
1975 hours in 25 hour increments. A selection of OFF will 
cancel this feature. When 

"Change Filter" 

is displayed, 

you can clear it by pressing Clean Display. In a typical ap-
plication, 200 hours of run time is approximately 30 days.
