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.
