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 functionality, keep all vents free of dust, debris, etc.
These units are warranted for a period of five years.
INSTALLATION
TDDA
1. Drill a hole in the duct.
2. Insert the temperature probe until the junction box is flat 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).
