2.1 Installing the mounting plate
1.
Plan the Location
–
The T-Stat should be mounted away from external sources of heat or cold
(doors, HVAC supply grill, exhaust from equipment, radio heads, etc.) and provide a good
representation of the shelter’s
temperature.
2.
Prepare the Area
- The mounting screw holes will line up on a standard duplex outlet box or can
be flush mounted to the wall. When flush mounting, ensure clearance for the wires to exit
through the center window on the back plate. Install outlet box or screw anchors and run
thermostat wires.
3.
Remove the cover
- The cover of the T-Stat is held on by four clips, two on the top and two on
the bottom. Remove the cover carefully, the cover may be snug and depressing the clips
through the slot openings may help in getting the cover off.
4.
Mount the Plate
- Dress the wires through the center window on the back plate and install
mounting screws. Tighten screws to ensure the plate is mounted securely, but do not over
tighten and warp the back plate.
2.2 Wiring
1.
Terminate the Wire Connections
–
Cut off excess wire, dress wire flush to the back panel and
strip 1/4” of insulation to expose conductor. Insert and tighten using the
Wire Terminations
diagram. Label all point to point connections at both ends of the cable.
