Optional Remote Sensor
(Used with Thermostats 668375301 &
668375401)
The fast, easy solution for temperature sensing
problems.
• For tamper prone areas
• Poor airflow areas
• Troubled applications
• Foam gasket prevents drafts through wall opening
• Mounts to standared 2" × 4" outlet box
• 2-3/4"W × 4-1/2"H

Optional Remote Sensor Installation
1.
Remove cover from remote sensor housing.
2.
Select an appropriate location for mounting the
remote sensor.
3.
Mount remote sensor unit using hardware provided.
4.
Install two strand shielded wire between remote
sensor and thermostat. Shielded wire must be used.
Note:
Do not run remote sensor wire in conduit with
other wires.
• Wire 1 should run between the S1 terminal on
the thermostat and the S1 terminal on the remote
sensor
• Wire 2 should run between the S2 terminal on
the thermostat and the S2 terminal on the remote
sensor
• Connect the shielding of the wire to the S2 terminal
on the thermostat
5.
Disable the main sensor (R12) on the thermostat by
cutting it from the circuit board.
