Wiring configuration error
N.B.: This board can be used for instant type boilers (VICTRIX Superior kW)
or with storage tank (VICTRIX ZEUS Superior kW ). The board automatically
recognises the type of boiler by means of the relative wiring of the P.C.B.
For the HERCULES Condensing boiler check the PRESENCE of the
No
connection jumper between clamps 6-7 of the connector X7.
