Freeze Protection
The thermostat operates the heat
whenever the room temperature falls
below 40°F (4.5°C) even when the
mode is set to off.
Cooling Operation
Cooling is available when the Mode
is set to Cool. The thermostat must
be configured for heat/cool/fan
operation in order for the cooling
operation to available.
To change the cool temperature setting,
push the
or
button to select a
preferred temperature setting for the
current schedule time period. The
Cool On symbol is shown on the display
when the thermostat is cooling.
To change the temperatures for the
other time periods, enter the Set Temp
menu by pressing both the
and
buttons together, press Menu to locate
the Set Temp menu, and press PRGM
to enter the menu.
When operating a forced air cooling
system, the thermostat uses a
differential of +/- 0.7°F (0.4°C).
Fan Operation
A fan is available when the thermostat
operates a forced air heating or
cooling system. The fan can be set
to On to allow air circulation through
the building. This is useful if the air
in the room is stale or if circulating
cool air from a basement throughout
a home can reduce the temperature
in the upper floor without
operating the cooling equipment.
Time Clock
The thermostat includes a time clock
that is automatically visible in the Home
menu when a programmable schedule
is used. If the schedule is not used, the
user has the option to select whether the
time is shown in the Home menu.
During a loss of power, the
thermostat continues to keep the
correct time and date for at least
4 hours.
If the power is off for more
than 4 hours, the user will need to
set the time.
Programmable Schedule
Energy savings can be achieved by
lowering the heating temperature
and increasing the cooling temperature
when the building is unoccupied or
during the night.
When operating on a programmable
schedule, a or a symbol is shown in
the home menu. The or indicates
the current operating temperature.
All schedules are stored in
permanent memory and are
not affected by a loss of power.
