INSTALLING THE THERMOSTAT
INSTALL MOUNTING PLATE (with WALL PLATE if required)
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.
Use the included screws and wall anchors
(if required) to attach the Mounting 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.

socket and slide the wire into the socket. Once the wire is inserted,
tighten the screw snugly. DO NOT OVERTIGHTEN the screws. Pull
gently on each wire after the screw is snug 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).
