T7047C,G ELECTRONIC THERMOSTATS AND REMOTE SPACE SENSORS OPERATION AND CHECKOUT RESISTANCE (OHMS) 2000 Operation 1800 The T7047C,G Electronic Thermostat or Remote Space Sensor control element is a negative temperature 1600 coefficient (NTC) thermistor. As the room temperature 1420 OHMS AT 1400 increases, the resistance of the thermistor decreases. 75 F (24 C) 1200 The change in the thermistor resistance causes the motor, system logic panel or system transmitter bridge 1000 circuit to
