5 SET HEAT ANTICIPATOR
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.

6 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.
