7047,G,H REMOE SPAE SENSORS OPERAION AND HEKOU Operation he 7047,G Remote Sensor control element is a negative temperature coefficient (N) thermistor. As the room temperature increases, the resistance of the thermistor decreases. he 7047H Remote Sensor control element is a positive temperature coefficient (P) thermistor. As the room temperature increases, the resistance of the thermistor increases. he change in the thermistor resistance causes the motor, system logic panel, or system transmitter bridge circuit to become unbalanced. As the electronic motor, system logic panel or system transmitter circuits react to rebalance the circuit, damper or valve movement, or sequential staging of heating and/or cooling equipment occurs. Low Range hermostat Use caution when setting temperatures below 40 F (5 ). A low temperature setpoint can result in temperatures below freezing in areas distant from the remote sensor. alibration he 7047 Remote Space Sensor is accurately calibrated at the factory. It cannot be field calibrated. heckout Allow the 7047 Remote Space Sensor to stabilize to ambient conditions before taking a resistance measurement. Measure nominal resistance according to the values described in the Specifications section. Measure the sensor resistance in accordance with the temperature curves. See Fig. through 7. heck operation of the complete control systems as directed in the associated technical publications. 7 6-0179
