4. Remove thermostat cover by pulling outward on
bottom edge of cover until it snaps free of the thermostat
base. Carefully remove and discard the foam plastic ship-
ping insert. This insert protects the switch and bimetal
assembly during shipping.
5. Set the adjustable heat anticipator indicator
(T822D,F,G only) to match the current draw of the primary
heating control (see Heat Anticipator Setting).
6. Push excess wire back through the hole and plug any
opening with insulation to prevent drafts that may affect
thermostat performance.
7. Loosely fasten the thermostat to the wall or outlet
box with a screw through the top mounting hole. Do not
tighten.
8. Level the thermostat exactly using a spirit level or
plumb line. Tighten the mounting screws.
IMPORTANT: An incorrectly leveled thermostat will
cause the temperature control to deviate from setpoint.
9. Replace the thermostat cover.
