Instructions / Assembly

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. 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.
Snap on Cover: Carefully align the cover with the base and snap
the cover onto the base.
This thermostat is easy to operate. Fig. 6 shows how the heating/cool-
ing system and fan operate when the switches are in various positions.
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 position (even if the
system switch is set to OFF, the fan will run if the fan switch is in the
ON position).
