Installing the Remote Sensors

Up to eight wired or wireless remote sensors may be installed on the thermostat (RS1) to control the temperature in other rooms. If more than one sensor is connected to (RS1) the thermostat will average the sensors to determine the displayed temperature reading. One wired or wireless remote sensor may be installed to read the outside temp- erature (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 dis- played. 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, therm- ostat wire. If multiple sensors are wired to the thermostat, then the total wiring distance of the furthest sensor should be used in determin- ing the appropriate wire gauge. The wired sensor can be connected to the thermostat using a two or three wire installation. If a two wire instal- lation 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.
