Limit Stat™
1
Thermostat Location
Turn off power to HVAC system.The Limit
Stat™ should be installed in a location that
represents the ambient space temperature.
Do not install the thermostat in an area where
drafts are present, near the floor, behind
doors or on an external wall. Avoid placing the
thermostat in areas where the air movement
is limited, affected by direct sunlight or other
areas not typical of the temperature in the
space.
2
Mounting the Subbase
When mounting the subbase, be aware that
drafts may travel down wall cavities and enter
the back of the thermostat through the control
wire hole in the wall. It is important to seal the
hole to prevent any drafts that might affect the
internal temperature sensor.

Pull the control wires through the large
opening in the thermostat subbase then level
and mount the subbase on the wall using the
supplied anchors and screws. Do not over
tighten the mounting screws as the
subbase may warp causing improper
seating of the thermostat connecting pins
to the terminal block.
Use a properly sized screwdriver and land
each wire to its dedicated terminal as
illustrated in Section 4. Do not over tighten
the terminal screws.
Check to ensure that all wires are landed
correctly and dressed properly to prevent any
shorts.
