NO
Wiring
CAUTION
Electrical Interference (Noise) Hazard.
Can cause erratic system operation.
Keep wiring at least one foot away from large
inductive loads such as motors, line starters,
lighting ballasts and large power distribution
panels.
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.
— Be sure wires have a cable separate from the
thermostat cable.
— Do not route temperature sensor wiring with
building power wiring, next to control contactors
or near light dimming circuits, electric motors or
welding equipment.
— Avoid poor wiring connections.
— Avoid intermittent or missing building earth
ground.
CAUTION
Electrical Shock Hazard.
Can cause electrical shock or equipment
damage.
Disconnect power supply before connecting
wiring.

Wiring must comply with applicable codes, ordinances
and regulations.
1. Wire C7189 Indoor Sensor to S1and S2
terminals on the thermostat. For an example of
general wiring of C7189, see Fig. 2.
2. Push excess wire back into the hole. Plug the hole
using nonhardening caulk, putty or insulation to pre-
vent drafts from affecting performance.
3. Remove C7189 cover.
4. Mount C7189 to the wall or junction box using the
screws and anchors provided.
5. Level the C7189 for appearance only. Device func-
tions correctly even when not level.
6. Install C7189 cover.
