The parameter shows the number of operating hours of the Advanced Power Controller.
The controller is in operation when line voltage is present and the power is non-zero.
The update in the non-volatile memory takes place every two hours and when the line voltage is switched off.

The parameter sets how the parameters are saved in the retentive memory.
With 0 (retentive memory enabled), when the device is first powered “on”, the device will utilize the last saved parameters for startup
(saved in retentive memory). Any parameters changed while retentive memory is disabled will not be saved when device is shutdown
(power off).
In any case, the parameters relating to the energy count, operating hour meter and maximum temperatures are always stored in retentive
memory.
Options: 0 = Retentive memory enabled
1 = Retentive memory disabled
