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.
[UP = 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.
[DOWN = 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 two items below are both located on the right side 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.
