The power recovery time (the period within which the voltage must be restored to have
an automatic restart) can be set between 15 and 3600 seconds or to ‘Infinite’. If the
power recovery time is set to ‘Infinite’, the dryer will always restart after a voltage failure,
no matter how long it takes to restore the voltage. See section Modifying Settings.
A restart delay can also be programmed, allowing for example the dryer and the
compressors to be restarted one after the other.
