SET TIMER

Adjust the timer by moving the knob clockwise
Do not reverse the knob.
When time is correctly set, the time indicator arrow
(triangle shape) points to the correct time and the corre-
sponding daytime (light) or nighttime (dark) portion of the
program dial (Fig. 8).
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 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
subbase, except for electric heat and heat pump systems.
