Start-up:
Regulation starts when the voltage is on.
1 Go through the survey of factory settings. Make any necessary changes in the respective parameters.
2 For network. Set the address in o03 and then transmit it to the gateway/system unit with setting o04.

- Cut out the supply voltage to the controller
- Keep upper and lower button depressed at the same time as you recon nect the supply voltage
