2.6 Mains Power Failure
Detection
The controller is equipped with a mains power failure

If the power supply fails for less than 10 minutes
during heating, the controller will continue from the
point in the program at which the power failed.
The timer is battery-buffered and may react to a pow-
er failure with a delayed start. The casting time will be
recalculated to reflect this.
The heating programme will not be restart-
ed if power is not restored until after the
programmed casting time has passed!
