slow cycle rate. If longer cycles are desired then set to
SL.
5) Cool Cycle Rate. Select either FA fast (default) or SL
slow cycle rate. If longer cycles are desired then set to
SL.
6) Auxiliary Cycle Rate. If condenser is heat pump select
either FA fast (default) or SL slow cycle rate. If longer
cycles are desired then set to SL.
7) Energy Management Recovery. Select either On or Off.
With a selection of On the system will start temperature
setback recovery early to reach the program setpoint at
the program start time. A selection of Off will start the
recovery period at the program start time.
8) Outdoor Remote Sense. A selection of On enables the
display of outdoor temperature with the connection of
F145-1378 outdoor remote sensor to the control.
9) Auxiliary Off. When condenser is heat pump configured
and outdoor sensor is connected, the option of locking
out the auxiliary heat based on outdoor ambient tem-
perature becomes available. Default is Off with a selec-
tion range from 80 degrees to 35 degrees in 1 degree
increment. When outdoor ambient is above the selected
temperature the auxiliary stages are disabled.
10) Dual Fuel Config. When condenser is heat pump and
indoor heat is gas and outdoor sensor is connected. A
selection from 0 to 50 in one degree increment is avail-
able. The Auxiliary/fossil fuel system is enabled, the heat
pump is disabled when the outdoor ambient temperature
is at or below the selection.
11) Dehumidification. Select from Off (default) to a setting
range from 40% to 80% Rh. If Rh is above setting, a
cooling call is initiated. To turn this feature Off raise set-
ting to its highest level 80%
12) Independent Dehumidification. Selection of Off (de-

active when humidity level is above the desired dehu-
midification setting.
13) Humidification. Select from Off (default) to a setting
range from 20% to 60% Rh. If Rh is below setting HM2
output is active with a call for heat. To turn this feature Off
lower setting to its lowest level 20%.

setting.
15) Compressor Lockout. Selection of Off (default) or On.
When On is selected the control will invoke a 5 minute

Configuration
Control can be configured at the equipment by utilizing the configuration plug in tool (F4-1400). The tool mounts to the back
of the interface and plugs into the bottom of the control via the RJ-11 connection. (Note: You cannot have two interfaces
connected to the control at the same time). With control powered, interface is used to configure the application and for
operational checks. Once configured, the interface can be installed in living area.
