Electronic Room Thermostat with LCD Display
CTE-5202
Installation
Rough-in Preparation
For optimum temperature sensor performance, the
thermostat must be mounted on an interior wall
and away from heat sources, sunlight, windows,
air vents, and air circulation obstructions (e.g.,
curtains, furniture).
Ifreplacinganexistingthermostat,labelwiresas
neededforreferencewhenremovingtheexisting
thermostat.
Completerough-inwiringateachlocationpriorto
thermostatinstallation.Cableinsulationmustmeet

CAUTION
To prevent damage to the board, do not insert
a screwdriver into any holes other than the two
outermost holes. To prevent mounting screw heads
from touching the circuit board in the thermostat, use
only the mounting screws supplied by KMC Controls.
Using other screws may damage the thermostat. Do
not turn screws in farther than necessary to remove
the cover.
