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
This selection disables cooling when outdoor temperature is below 55_F. 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. Set to On
to prevent cooling below 55_F.
Factory default is OF (off).
Option 07 — Zoning
This selection should be set to On when the thermostat 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
thermostat.
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.
