Hi All,
I am Ludo a new member. I have an elan boiler 2 with a new contrôler FP715- (Si Electronic Programmer ).
Recently, when the water heater program start, it doesn't heat the water tank but heat only heaters and excessively although the heaters program is not on.
Any idea ? Do you think the expansion vassal could be the problem? Thanks.
