Recommended Floor Temperatures
Settings
Recommended maximum floor temperature is 90 °F (32 °C)
for most floor covering types except wood. Suggested
maximum floor temperature for wood floor is 85 °F (29.5 °C).
Freeze protection temperature for garages and basements is
suggested to be set between 41 °F - 45 °F (5 °C - 7.2 °C).
See ISU settings (1055, 3250, and 5120-5170)

Wire the floor/slab sensor to the S terminals on the UWP if
EIM is not used. If EIM is used, wire floor/slab sensor to any of
the sets of S terminals. Make sure the floor/slab sensor
settings match the wiring. See ISU settings (1055, 3250, and
5120-5170).
* A 10K ohm TekMar slab sensor could be used in place of the
AC112 01 Floor sensor
IMPORTANT
Erratic temperature readings from a sensor can
occur as a result of any of the wiring practices
described below. Avoid these practices to assure
correct operation. Use shielded cable to reduce
interference if rerouting of sensor wiring is not
possible.
— Be sure wires have a cable separate from the ther-
mostat cable.
— Do not route temperature sensor wiring with build-
ing power wiring, next to control contacts or near
light dimming circuits, electric motors or welding
equipment.
— Avoid poor wiring connections.
— Avoid intermittent or missing building earth
ground.
