Use the included screws and wall anchors (if required) to attach the Mount-
ing Plate to the wall, making sure the wires go through the center opening.
Note the correct position indicated by the UP arrows molded into the
plastic.
To cover paint or screw holes on the wall behind the thermostat, insert
the Wall Plate between the Mounting Plate and the wall as shown. Both
plates are secured with the same screws.
Note: See Appendix E
for optional junction
box mounting.
Note: Use 3/16” drill for wall
anchors if no stud is present.

ATTACH WIRING
To insert a wire, flip up the locking lever that corresponds to the
labeled wire socket and slide the wire into the socket. Once the
wire is inserted, flip the lever down to lock the wire in position.
Pull gently on each wire after the locking lever is closed to make
sure it is secure. Inspect the wires for oxidation and integrity.
NOTICE: A factory supplied jumper is provided between RC and RH.
This should be removed in two transformer systems (See Appendix A).
