16.2 Possible Solutions
Sensor Error
If any of the sensors are bad try the following:
•
Reset the controller by taking power away at the breaker, or unplugging it.
•
Determine which sensor is bad, then check the connection inside the controller door. If the
error is for sensor 3, read the section below to determine alternate course of action.
•
Determine which sensor is bad, then check the sensor that is hanging in the house to make
sure that it has not been damaged.
•
Replace the bad sensor.
