DO NOT LET WIRES FALL BACK INTO WALL. 3. Connect wires beneath terminal screws on subbase using appropriate wiring schematic (see figs. 3 through 8). 4. Place subbase over hole in wall and mark mounting hole locations on wall using subbase as a template. (Installation instructions continue on page 5.) TABLE 1.

Fasten subbase loosely to wall, as shown in fig. 3, using two mounting screws. Place a level against bottom of subbase, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten subbase snugly, use plastic expansion plugs to secure subbase. 7. Push excess wire into wall and plug hole with a fire- resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation. ATTACH THERMOSTAT TO SUBBASE IT IS RECOMMENDED THAT YOU PROGRAM THE THERMOSTAT WITH BATTERIES INSTALLED BEFORE ATTACHING ON SUBBASE (see OPERATION GUIDE for programming instructions). CAUTION! POWER TO THERMOSTAT MUST BE OFF BEFORE ATTACHING THERMOSTAT TO WALL. FAILURE TO TURN OFF POWER BEFORE ATTACHING THERMOSTAT MAY CAUSE EQUIPMENT DAMAGE DUE TO RAPID COMPRESSOR CYCLING. 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. 9). 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.
