7. Loosely fasten the thermostat to the wall or outlet
box with a screw through the top mounting hole. Adjust
the thermostat so it is approximately level. Start the sec-
ond screw through the bottom mounting hole but do not
tighten.

a spirit level or plumb line. Tighten the mounting screws.
IMPORTANT: An incorrectly leveled thermostat will
cause the temperature control to deviate from setpoint.
