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
time guard and cycle timers. The minimum On time is still controlled by the
Thermidistat Control.
Default is OF (off).
Option 08 — Auxiliary Heat Lockout Temperature
This selection is available on heat pump systems with a valid outdoor
temperature sensor connected. Available settings are: Off, 5, 10, 15, 20, 25, 30,
35, 40, 45, 50, 55.
OF (off) − function is disabled. Auxiliary heat is allowed to operate whenever
sufficient demand for heat is available.
5 to 55_F (−15 to 13_C) − Outdoor temperature above which the auxiliary heat
is not allowed to operate (unless MODE is set to Emergency Heat). If room
