SET HEAT ANTICIPATOR

Adjust the heat anticipator lever to match the current

rating of the primary control for the proper cycle rate (Fig. 9).

Adjustable anticipation must be set for total current of

heat and fan control.

The current rating is usually stamped on the control or

valve (Fig. 10), or a setting may be given in the device
instructions.

If no current rating or heat anticipator setting is given,

measure the current with an ammeter. Proceed with the fol-
lowing steps.

Remove the thermostat from the wallplate or subbase.

Connect an ac ammeter of appropriate range (about 0A to
2A) between the R and W terminals on the wallplate or sub-
base except for electric heat and heat pump systems.

Let the system operate for one minute.
Adjust the heat anticipator lever to match the number that

reads on the ammeter.

ATTACH THERMOSTAT COVER

Make sure the packing inserts in the thermostat base are

removed.

Place the two tabs on the upper edge of the cover into the

mounting slots in the thermostat base (Fig. 11).

Swing the cover downward until it catches at the bottom

of the base.
