SET CLOCK

Adjust the clock by moving the minute hand in a clock-
wise direction. Do NOT reverse the minute hand.
When time is correctly set, the time indicator arrow (Fig. 8)
must point to the correct time and the corresponding daytime
(light) or nighttime (dark) portion of the program dial.
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
following steps.
Remove thermostat from wallplate or subbase. Connect
an ac ammeter of appropriate range (about 0A to 2A) be-
tween the R and W terminals on the wallplate or subbase
except in electric heat and heat pump systems.
