2. Connect wires beneath terminal screws on subbase
using wiring schematic for your particular application
(see figs. 3 through 6).
3. Place subbase over hole in wall and mark mounting
hole locations on wall using subbase as a template.
4. Move subbase out of the way. Drill mounting holes.
5. 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.
6. Push excess wire into wall and plug hole with a fire-
resistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation.
