Power Failure
All the parameters and set points are memorized and do not need to be reentered. Depending on UP05 the unit will
remain switched off, switch on automatically or return to the operation mode it was in before the power failure.
Deluxe version only: Timer operation and daytime setting will be retained for 24h. The controller has to be connected
to a power supply for at least 10 hours for the backup function to operate accordingly.
Frost Protection
The controller will enter frost protection mode if the room temperature drops below 5°C (41°F). All heating outputs will
be fully opened. Frost protection mode will be left once the temperature reaches 10°C (50°F). Frost protection display
will remain until a button is pressed. Frost protection can be enabled/disabled using user parameter UP-09
