Note: This setting is not minutes or degrees. It is numeric set-
ting that will influence the internal thermostat calculation
for staging.
35. 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.
36. 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.

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

sible heat pump malfunction, the thermostat will turn off

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. 37. Select Programmable Blower Balance Point (bP) –
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.
Applicable with HP1 or HP2 selected, dF On with outdoor
sensor. Requires 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 80° (disabled), but can be
set from 20° to 79°. Select an outdoor temperature where
the air coming out of the ducts begins to feel cool and the
thermostat will lower the fan speed to circulate warmer air.
38. 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. (See page 10 for Humidity setpoint range)
39. 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.
40. 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.
29. 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.
30. 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.
31. 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.
32. 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.
33. 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.
34. 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
41. 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
