Installation Instructions

Check Dip Switch
Ensure which switch is correct for your
system. Dip switches are located on the
back of the thermostat.
This switch (GAS or ELEC) controls how the
thermostat will control the Fan (G) terminal in
heating mode. When
GAS
is chosen, the thermostat
will not energize the Fan (G) terminal in heating.
When
ELEC
is chosen the thermostat will energize
the fan in heating.
For Heat Pump Only
When the
GAS/EL
or
HP
dip switch is configured for
HP
, this dip switch (O or B) must be set to control
the appropriate reversing valve. If
O
is chosen, the
W1/O/B
terminal will energize in cooling. If
B
is
chosen, the
W1/O/B
terminal will energize in heating.
This dip switch configures the thermostat to control
a conventional gas/electric system or a heat pump.
If your system is anything other than a heat pump,
leave this switch set for
GAS/EL
.
