5.Move subbase out of the way. Drill mounting holes.

6.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.
