GAS / ELEC SLIDE SWITCH (FAN OPERATION):
This switch is a physical component by itself on the
circuit board, and is much larger than the DIP
switches listed above. [DOWN = GAS, default] This
setting lets the heating system control the blower
fan automatically by itself. Systems that would
typically use the “GAS” setting would be: natural
gas, propane, or oil furnaces. This setting has no
effect upon Cool mode operation. [UP = ELEC/HP]
This setting runs the system’s blower fan when
heat is called for, and is required for heating systems that do not control their
own fan while the thermostat is in HEAT mode. Heat pump systems, and units
with an electric heating element typically require this setting.
Once the hardware options are set, install two new Energizer
®
or DURACELL
®
"AA" size alkaline batteries. Ensure that the batteries are installed in the proper
direction as per the markings shown in the battery tray. If the batteries were
already installed before changing the hardware setup options, change the
position of the HEAT/OFF/COOL System Mode switch to accept the new hardware
option switch settings.
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
