select Off. Some auxiliary heaters require a separate G signal
to turn on the blower. In this case, select On. Allowable
selections are On and OF (off). Default is OF (off).
OPTION 06 — COOLING LOCKOUT — Disables cooling
if outdoor temperature is below 55

°

F. It requires an outdoor

temperature sensor. Setting is not available if outdoor
sensor is not connected. Set to OF (off) to allow cooling
below 55

°

F. Set to On to prevent cooling below 55

°

F. If the

compressor is already operating and the outdoor air
temperature drops below 55

°

F, the compressor will continue

to operate until the cooling cycle has completed. Default is
OF (off). If this selection has been set to On and the
outdoor air sensor fails, an outdoor air temperature error
will be displayed and this configuration will be available for
the installer to change the setting from On to Off.
OPTION 08 — AUXILIARY HEAT LOCKOUT TEM-
PERATURE SETTING — This option is only 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

F - Outdoor air temperature above

which the auxiliary heat is not allowed to operate (unless
MODE is set to Emergency Heat). Default is OF (off).
OPTION 11 — ADJUSTABLE SET POINT DEADBAND
— This option is not available on Heat Only or Cool Only
systems. The selection allows the installer to choose the
number of degrees between the heating and cooling set
points. Higher numbers provide less precise temperature
control but save energy, Lower numbers provide comfort
with more energy use. Allowable selections are 1 to 6

°

F.

The default is 2

°

F.

OPTION 12 — SMART RECOVERY — Smart Recovery is
a function that transitions the room to the next programmed
set points as energy efficiently as possible. OF (off) means
set points change precisely at setback recovery time. 30, 60,
or 90 selects the number of minutes before next pro-
grammed period that recovery starts. Recovery takes place
smoothly during the selected recovery time, ending at the
recovery time and temperature which is programmed.
Allowable selections are OF (off), 30, 60, and 90. The
default is 90.
OPTION 13 — ROOM AIR TEMPERATURE OFFSET
ADJUSTMENT (OFFSET) — Selects the number of
degrees to be added to the displayed temperature to
calibrate or deliberately miscalibrate the measured room
temperature. The range is from –5 to +5

°

F. The default is 0.

OPTION 15 — AUTO MODE AVAILABILITY — This
option is not available on Heat Only or Cool Only systems.
Allows the installer to select auto changeover mode in
addition to heat and cool. It allows the thermostat to
automatically change between heating mode and cooling
mode when sufficient demand for heating or cooling exists.
On - Auto mode is available. OF- Auto mode is not
available.  The default is On.
OPTION 16 — MAX CYCLES PER HOUR — This
selection limits the number of cycles per hour that the
thermostat allows the system to operate. Selections are 2, 4,
