Wiring the 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.
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 the C7089 Outdoor Sensor to the S terminals on the
humidity control. If leadwire provided with C7089 is not long
enough (60 in.), run a cable to a hole at C7089 location.
• Using color-coded, 18-gauge, shielded thermostat wire is
recommended. For example of general wiring of C7089, see image at
right.
• Pigtail wiring can be used.
2. Mount C7089 in its mounting clip.
3. Plug wiring hole using nonhardening caulk or putty.
