Outdoor Temperature Sensor Option 2 —

Outdoor Air Intake

Mount the sensor in the outdoor air intake by drilling a 1/4 inch hole within

12" of outside. Angle the hole towards the outside. Insert the temperature

sensor into the intake pipe until the sensor is at least 2" outside the

wall of the house. Seal the hole and secure the wire so it cannot be

accidentally pulled out. See Figure 4 for example installation.

CAUTION: electrical interference can cause erratic system operation.

•

Do not route temperature sensor wiring with building power wiring, next

to control contactors, near light dimming circuits, or electric motors.

•

Use shielded cable to reduce interference when rerouting is not

possible.

•

Be sure wires have a cable separate from the humidistat cable.

•

See Figure 5 for wiring diagram.
