Installing the thermostat
1. Install the base onto an elec-
trical box.
2. Place the FAN switch as fol-
lows:
3. Place at Yes if you have a
fan-forced heater (to pre-
vent premature burnout of
the motor).
4. Leave at No for better tem-
perature regulation if you do
not have a fan-forced heater.
FAN switch
If you change the FAN switch position after
you have already applied power to the thermo-
stat, disconnect power to the thermostat at the
electrical panel for 3 seconds. The thermostat
will use the new setting when you reapply
power.
