CAUTION:
• Do not run the Room-Mate Comfort Controller wiring in any conduit with line powered wiring.
• Room-Mate Comfort Controller is powered by 24Vac, the 24Vac power and ground wires should be
run in a separate cable from signal wires. Separate the power cable from the signal cable by at least
15cm (6 inches) along the entire wiring run.
• Failure to wire devices with the correct polarity using a shared transformer may result in damage to
any device powered by the shared transformer.
• The Room-Mate Comfort Controller measures building interior temperature and should be located on
an interior building wall. The controller can be mounted directly on the wall surface if acceptable by
local codes.
• Do not mount the controller in drafty locations such as near air conditioning or heating ducts, over
heat sources such as baseboard heaters, radiators, or directly above wall mounted lighting dimmers.
Do not mount the controller near a window that may be opened, or near a wall corner or door.
Controllers mounted in these areas will have inaccurate and erratic sensor readings.
• Mount the controller approximately 150cm (5 ft) from the floor, in an area representing the average
temperature in the space. Allow at least 120cm (4 ft) between the controller and any corner and
mount the controller at least 60cm (2 ft) from an open doorway.
