Set anticipator to match the setting of your old thermostat you noted in Step 3, or, the 
anticipator should be set to match the current rating stamped on your main heating 
control. The heat anticipator is adjustable from 0.15 to 1.2 amps. Adjust the anticipa-
tor by rotating the contact arm (see fig. 5). The anticipator setting is indicated by the 
numbers on the base that the pointer points to. If you are unsure where to set the 
anticipator contact the heater manufacturer for a recommended setting.
Move the pointer 
counterclockwise to
lengthen heating system cycles; move 
clockwise to shorten heating cycles. 
Adjustments should not be greater than 
1/2 marking at a time.
For millivolt operation, rotate contact arm to 
Millivolt Link.
Snap on Cover: Carefully align the cover 
with the base and snap the cover onto 
the base.

NEW THERMOSTAT OPERATION
Thermostat on Subbase. After power is turned on, use the system switch to select 
either heating or cooling, or to turn the heating/cooling system off. Use the fan switch 
to control fan operation. When the fan switch is in the 
AUTO position, the fan will 
cycle with the heating or cooling system (the fan will not run if the system switch is 
in the 
OFF position and the fan switch is in the AUTO position). When the fan switch 
is in the 
ON position, the fan will run continuously, regardless of system switch posi-
tion (even if the system switch is set to 
OFF, the fan will run if the fan switch is in the 
ON position).
Thermostat on wallplate. For heat only move the temperature lever to the highest 
temperature. For cool only move the temperature lever to the lowest temperature.
