Operating without panel
When ignition is turned on, the Control panel and the Control board intercommunicate with one another.
In case there is a communication failure between them, the panel will indicate after 15 seconds and
the Control board will turn automatically on the Automatic Control Mode, with a previously stored set-
point. This is a failure condition, although it enables the equipment to work even without communication
between the modules. If the equipment is operating and there is a communication failure, it will keep on
operating on the selected function until ignition is turned off.
