2.6.2 Remote Temperature/Humidity Sensor

Chapter 2: Installation

2.6.2 Remote Temperature/Humidity Sensor

Depending on the type of control selected, the temperature/humidity (T/H) sensor may be factory-mounted or shipped loose for field installation. The remote sensor must be located so that it will properly sense the temperature/humidity conditions to be controlled. The T/H sensor should not be mounted near a doorway or an area where it would be exposed to direct sunlight. When locating the sensor, consider the length of wire to be used. The sensor is typically provided with a 20-foot long cable.

As an option, a 75-foot or 150-foot long cable may be provided. Follow the steps below to mount the sensor.

Figure 2-6. Temperature/humidity sensor.

1. Remove the cover from the base of the sensor by squeezing it at the top and bottom.

CAUTION

Be careful not to damage the exposed temperature/humidity sensors on the PC board when removing the cover. The sensors can be damaged if handled improperly.

2.Place the base temporarily against the mounting surface.

3.Level the base. Mark and drill mounting holes through at least two of the available slotted holes.

4.Run the 3-conductor shielded cable through the opening in the base, then secure the base with screws ensuring the word “TOP” on the PC board is oriented upward.

5.Make the wiring connections. Refer to Section 2.9, Utility Connections and refer to the wiring diagram supplied with your unit.

6.Seal the hole in the wall behind the sensor.

7.Replace the cover plate on the base.

CAUTION

The sensor can be damaged if handled improperly. Take care not to damage the exposed temperature/humidity sensor on the PC board. Do not touch the sensor because this will affect its accuracy.
