CHECKOUTThe C7772 Wallplate Temperature Sensor is immediately
operational after wiring connections are made. Use an
accurate thermometer of ±1°F (0.5°C) to measure the
temperature at the sensor location. To verify sensor accuracy,
use an ohmmeter to measure the resistance across the
sensor wires and use Table 2 to check the accuracy of the
specific model.
