These items below are all located behind the door on the front of the
thermostat. To open the door, pull outwards using the small indentation
in the center of the top edge of the thermostat housing.
HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to
control your heating system, and COOL to control your cooling system.
The OFF position will disable both the heating and cooling units.
AUTO / ON, FAN MODE SWITCH: When this switch is in AUTO, the blower
fan (if present in your system) will automatically cycle on and off by itself
while heating or cooling is running. When in the ON position, the blower
fan will run constantly with or without a demand for heating or cooling,
even when the System Mode switch is in the OFF position.
NOTE: The Fan Mode switch only works if your system provides a wire for
the thermostat’s “G” wire terminal, to control a blower fan. The Fan Mode
switch has no effect in systems that do not have a blower fan (such as a
hot water radiator system).
MULTI-FUNCTION, SET SLIDE SWITCH: This switch provides an easy
way to quickly access the most commonly used thermostat settings. This
switch has 4 individual positions, and unless a specific setting is being
adjusted, this switch should always remain in the RUN position for the
thermostat to control the room temperature. The other Set Slide switch
positions are described in greater detail in the ADVANCED FEATURES
section. NOTE: this switch is only operable when the thermostat is in
“Programmable” mode. When the thermostat is used in “Manual” control
mode, all 4 of the switch positions will act like the RUN position, except
the “AIR FILTER” position.
