PRODUCT OVERVIEW

The TDDA, TOA, and TWxA temperature sensors are equipped with a highly accuracy temperature transmitter with analog output compatible with most building control systems. To maintain accurate func tionality, keep all vents free of dust, debris, etc. These units are warranted for a period of ve years.

INSTALLATION

TDDA

1. Drill a hole in the duct.

2. Insert the temperature probe until the junction box is at against the outer surface of the duct.

3. Use screws to secure the junction box to the duct.

4. Wire as shown (see Wiring section).

TOA

1. Locate the sensor in an outside area, out of direct sunlight (e.g. under an eave, north side of the building).

2. Mount the housing.

3. Wire as shown (see Wiring section).

TWxA

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Mount the housing vertically on an interior wall in the area to be monitored, in a location where air circulates freely. Locate unit away from air outlets, corners, exterior walls, windows, and doors.

2. Wire as shown (see Wiring section).
