Setting the maximum ORP metering time
The dosing time is a safety feature and prevents dangerous overdosing in case of failure. Attention! The larger the
maximum dosing time is set, the more chlorine solution can be released in an uncontrolled manner in case of any
damage to the dosing tube!
The metering time must be adapted to the actual pool size.

ORP Power-on delay
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.
