SWITCH #8 (BATTERY MONITOR):
[OFF/DOWN = ON, default] This
setting, regularly monitors the battery level, and shows “LOW BAT” on the
screen if the batteries need to be replaced. Use this setting at all times
when batteries are present in the thermostat. [ON/UP = OFF] This setting
only applies if you are NOT physically using batteries in the thermostat,
and are powering the thermostat entirely from the system (“C” wire
terminal).
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.
