1. go20L REMOTE INDOOR SENSOR Introduction The indoor sensor is designed to sense the air temper ature at a remote location and send this information to the thermostat Once connected the thermostat responds only to the temperature sensed by the indoor sensor s or by averaging the reading between the thermostat and the remote sensor Installation of Indoor Sensor 1 Install the thermostat according to the instruction manual supplied with it Check that the thermostat is operating Display shows the correct temperature CAUTION Remove the thermostat from the subbase while wiring the sensor to avoid damage from live wires This is important 2 Install shielded or nonshielded two wire twisted cable from the thermostat to the remote sensor location Maximum distance is 330 ft 100m 3 Open the sensor case by grasping the side and pulling the two halves apart 4 Use the subbase as a template to mark the mounting hole locations on the wall Drill size for the wall anchors is 1 4 inch Mount the subbase over the wires coming out of the wall using the two screws and anchors provided Do not use hex head screws 5 Strip 1 4 inch of insulation from the two wires at the remote sensor Install the wires in the terminals The wires can be connected with either polarity Seal the hole in the wall around the cable to eliminate any draft that might affect the sensor 6 Connect the wires on the thermostat subbase to the sensor te2. or 9020i Use twisted pair wiring 22AWG minimum with a maximum length of 330 feet or 100m 2 Replace cover on thermostat Turn on power to unit and proceed with programming per instructions on the display or in the user s manual Indoor sensor terminal block os os oS To sensors gt os o o7 o7 ooo Ss Outdoor sensor terminal block Invensys Climate Controls Americas 515 South Promenade Avenue Corona CA 92879 1736 United States of America Made in Mexico www aboutinsight com 2003 Invensys 111 291D
