replacing a faulty room controller/sensor

1.

Identify the sensor/controller to be replaced from the flashing output LED.

2. Switch OFF power to the master.
3. Replace the sensor/controller.

4.   Switch ON power to the master.
5.   Set the master to learning mode by switching DIP-3 to ON.
6.   If the sensor/controller is wireless, press the learning mode button on the sensor/controller.

See “Installation” under “Waterline Room Sensors - Type WLTx”.

If the sensor/controller is wired, proceed to step 7.

7. Check that the corresponding output LED has changed from flashing to permanently ON.
8. Reset DIP-3 to OFF.

Important: Set the channel selector on the new sensor/controller to the same channel as

the defective sensor/controller that is replaced
