Wiring C7089U1006 Outdoor
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.
Use shielded cable to reduce interference when
rerouting is not possible.
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 sensor wiring is not possi-
ble.
— 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 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 C7089U1006 Outdoor Sensor to S1, S2, S3, or
S4 terminals on the EIM. If leadwire provided is not
long enough (60 in.), run a cable to a hole at
C7089U1006 location.
a. Using color-coded, 18-gauge thermostat wire is
recommended. For example of general wiring of
C7089U1006, see Fig. 356.
b. Pigtail wiring can be used.
2. Mount C7089U1006 in its mounting clip.
3. Plug wiring hole using nonhardening caulk or putty.
