REMOVING THE THERMOSTAT FROM THE SUBBASE
1. Insert a flat blade screwdriver or coin 1/8"
into the slot located in the bottom center of
the thermostat case and twist 1/4 turn.
When you feel or hear a click, grasp the
case from the bottom two corners and sep-
arate from the subbase as shown in the dia-
gram at the left. Some models require more
force than others when separating due to
the number of terminals used.
2. Swing the thermostat out from the bottom.
3. Lift the thermostat up and off the subbase.
4. Place the rectangular opening in the subbase over the equipment control wires protruding from
the wall and, using the subbase as a template, mark the location of the two mounting holes
(exact vertical mounting is necessary only for appearance).
5. Use the supplied anchors and screws for mounting on drywall or plaster; drill two 3/16" (5mm)
diameter holes at the marked locations; use a hammer to tap the nylon anchors in flush to the wall
surface and fasten subbase using the supplied screws. (Do not over tighten!)
6. Connect the wires from your system to the thermostat terminals as shown in the wiring diagrams.
Carefully dress the wires so that any excess is pushed back into the wall cavity or junction box.
Ensure that the wires are flush to the plastic subbase. The access hole should be sealed or
stuffed to prevent drafts from affecting the thermostat.
