A. Mount base and adaptor plate: Mount base to wall using screws
provided (see Fig. 1).
B. Attach wires: Attach one wire to R and the other wire to W on
base.
MOUNTING AND WIRING
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 rat-
ing stamped on your main heating control. The heat anticipator is
adjustable from 0.15 to 1.2 amps. Adjust the anticipator by rotating
the contact arm (see fig. 2). 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.
Snap on Cover: Carefully align the cover with the base and snap
the cover onto the base.
After power is turned on, slide temperature lever to desired setting.
To turn heat off, slide lever all the way to the left until it clicks.
