Remote Sensor Installation (Optional)

Terminals S1 and S2 can be used for an outdoor sensor or for an indoor remote sensor .
The outdoor sensor is used to change system operation based on the outdoor temperature . It can be used for heat
pumps with gas/oil backup or heat pumps with electric backup .
The indoor remote sensor is used to read the indoor temperature in a different location . This is beneficial when the
thermostat is not mounted in the ideal location .
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 is recommended .
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 . Configure the thermostat to operate with the remote indoor sensor (see Configuration Mode setting 17,
Page 17) or use it for an outdoor sensor for heat pump systems (see Page 9) .
