Mounting
Location: Install the sensor in a location where it will sample the average
duct air temperature. Avoid areas where the air is stratified because these
areas can cause sensing errors.
TE-705: Refer to Figure 2 for mounting dimensions.
1. Drill a 7/16-inch (11 mm) hole into the duct where the sensor will
be installed.
2. Gently uncoil the sensor’s rigid probe and insert it into the duct.
3. Use the flange as a template to mark and drill two holes for the #8
self-tapping sheet metal screws (not provided).
4. Fasten the sensor to the duct with the sheet metal screws. Refer
to Figure 1.
Figure 1 - Installing the TE-705 Sensor
CHECKOUT
Allow the sensor to stabilize in the duct air stream for a minimum of five minutes
before taking a resistance measurement.
1. Disconnect the sensor lead wires from the controller.
2. Connect an ohmmeter across the lead wires.
3. Ensure that nominal resistance measurements are in accordance
with the resistance/temperature curves. (Refer to Tables 1 & 2.
For complete Resistance vs. Temperature tables, please refer to
TI.700-11 - Temperature Sensor section.)
4. Reconnect sensor lead wires to the controller.
5. Check operation of the complete control system.
MAINTENANCE
Regular maintenance of the total system is recommended to
assure sustained optimum performance.
FIELD REPAIR
None. Replace with a functional unit.
