Installing the Remote Sensors Installing the Remote Sensors
Up to eight wired remote sensors may be installed on the thermostat
(RS1) to control the temperature in other rooms. One wired or wireless
remote sensor may be installed to read the outside temperature (RS2).
If a sensor(s) is connected to RS1 and is programmed to control the
thermostat, the degree icon on the thermostat will blink once per
second to indicate that a remote sensor reading is being displayed.
The wired sensor can be connected to the thermostat with up to 150'
of 18 ga., 300' of 20 ga., or 450' of 22 ga. unshielded, thermostat
wire.
This wire MUST be completely separated from the thermostat
or any other control wiring and must NOT be in the same
conduit as high voltage wiring.
