Option 03 — Fahrenheit/Centigrade
Select between Fahrenheit (F) and Centigrade (C) operation. Factory default is
Fahrenheit (F).
Option 04 — Fan (G) On With W/W1
This selection determines whether fan (G) output is to be On or OFF when any
W/W1 (furnace or strip heat) output is On. Most furnaces and fan coils manage
their own blowers and do not require separate G signal. For these applications,
select OFF. Some auxiliary heaters require separate G signal to turn on blower. In
this case, select On.
Default is OF (off).
Option 05 — Room Air Temperature Sensing (programmable models only)
This selection determines which sensor the control will use for measuring room
air temperature. Room air temperature can be sensed in one of three ways; the
local sensor (L) located on the Display Module, the remote room air sensor (r),
or the average of local and remote sensors (Lr). Settings are L, r, Lr.
Default is L.
Option 06 — Cooling Lockout Below 55_F/13_C
This selection disables cooling when outdoor temperature is below 55_F/13_C.
It requires an outdoor temperature sensor. Setting is not available if valid outdoor
sensor is not connected. Set to OF (off) to allow cooling below 55_F/13_C. Set
to On to prevent cooling below 55_F/13_C.
Factory default is OF (off).
Option 07 — Zoning
This selection should be set to On when the Thermidistat Control is to be used as
part of a zoning system. It is assumed that the zoning equipment will take care of
