2.1 Installing the mounting plate
1. Plan the Location – When zone mounting, the T‐Stat should be near eye level, on an interior
wall and away from external sources of heat or cold (windows, doors, HVAC supply ducts,
Servers, etc)
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, run
thermostat wires, sensor wire, and bus cable.
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.
