FORE ATTACHING THERMOSTAT TO WALL. FAILURE TO TURN THERMOSTAT OFF BEFORE ATTACHING TO WALL MAY CAUSE EQUIPMENT DAMAGE DUE TO RAPID COMPRESSOR CY- CLING.
To attach thermostat to subbase, line up the plastic snap guides at the bottom of the thermostat and the three connector pins on the thermostat with the connectors near the bottom left section of the subbase (when viewed
from the front). Gently pivot the thermostat up until the six pin connectors and the plastic snaps lock into place (see fig. 12). Be gentle when attaching thermostat. If the thermostat does not seem to be attaching to the subbase easily, make sure that the connector pins and plastic snaps are properly aligned, and that excess wire is pushed into the wall. Damage to the thermostat may occur if force is used.
