Wire Indoor Sensor
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 separate cable 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

CAUTION
Electrical Shock Hazard.
Can cause electrical shock or equipment damage.
Disconnect power supply before connecting wiring.
Wiring must comply with local and national codes, ordinances and regulations.
1. Wire Indoor Sensor to S1 and S2 terminals on the thermostat. For an example of general
wiring of 435-0013, see Fig. 23 to wire one sensor and 24 to wire multiple sensors.
2. Push excess wire back into the hole. Plug the hole using non-hardening caulk, putty or
insulation to prevent drafts from affecting performance.
3. Remove 435-0013 sensor cover.
4. Mount 435-0013 to the wall or junction box using the screws and anchors provided.
5. Level 435-0013 for appearance only. Device functions correctly even when not level.
