1. Check Installer Setup Number (ISU) 4 to ensure it is
set to use the remote sensor. (See Table 4 on
page 11).
2. Wire sensor to Rs and Sc thermostat terminals.
3. Push excess wire back into the hole. Plug the hole
using non-hardening caulk, putty or insulation to
prevent drafts from affecting performance.
4. Remove sensor cover.
5. Mount sensor to the wall or junction box using the
screws and anchors provided.
6. Level the sensor for appearance only. Device func-
tions correctly even when not level.
7. Replace sensor cover.
NOTE: For complete wiring instructions, please follow
the installation instructions provided with the
remote sensor.
Sensor Wiring for Temperature
Averaging
Fig. 4–Fig. 6 illustrate sensor wiring for temperature
averaging applications.
Fig. 4. Wiring four TR21 (20K ohm) sensors.
Fig. 5. Wiring two TR21-A (10K ohm) sensors to
provide a temperature averaging network.
Fig. 6. Wiring two TR21 (20K ohm) sensors and
one TR21-A (10K ohm) sensor to provide
a temperature averaging network.
Thermostat Wiring Diagrams
The figures in this section illustrate typical wiring for:
