*) This setting will only be possible if a data communication module has been
installed in the controller.
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you recon nect the supply voltage
