Setting the ORP power on delay
This setting should only be adjusted by a professional, and is only accessible in Expert Mode.
The controller only starts up after a delay period once the power supply has been provided and once
external enable has been switched on (e.g. filter control unit). This power-on delay is necessary because a
period specific to the overall system elapses once the filter pumps have been switched on before the
completely mixed water reaches the sensors. This mixing process is mainly dependent on the pool size, the
dimensions of the filter pump, the pipe length and the filter itself.
The delay period can, if required, be adapted to the actual pool size.
