Installing the Remote Sensors

One wired or up to eight wireless remote sensors may be installed on the thermostat (RS1) to control the temperature in another room. If more than one wireless sensor is used on RS1, the thermostat will ave- rage the sensors to determine the displayed temperature reading. One wired or wireless remote sensor may be installed to read the outside temperature (RS2). If a sensor is connected to RS1 and is program- med 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. The wired sensor can be connected to the therm- ostat using a two or three wire installation. If a two wire installation is required, then RS+5 must be connected to RSGND (see below).

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.
