Warning
If activated and provided the module was in the automatic operation mode, the compressor will
automatically restart if the supply voltage to the module is restored within a programmed time period.
The power recovery time (the period within which the voltage must be restored to have an automatic
restart) can be set between 1 and 255 seconds or to Infinite. If the power recovery time is set to
Infinite, the compressor will always restart after a voltage failure, no matter how long it takes to restore
the voltage. A restart delay can also be programmed, allowing e.g. two compressors to be restarted
one after the other.
