6.1 ELECTRONIC BOARD - JU MPER
Fondital Group has standardised the
electronics of all of its boiler models, in
fact besides the jumper for changing the
gas, we find two other jumpers for
choosing the boiler model: instantaneous
with plates, heating only, with separate
tank, with micro-water tank and macro-
water tank.
In position F2PIA mono-thermal combination boiler with secondary plate heat exchanger
In position F3RIS heating only, suitable for external water tank
In position F4BOI combination boiler with water tank
In position F5MIC combination boiler with micro-water tank
In position F6MAC reserved for future developments
F2PIA F3RIS F4BOI F5MIC F6MAC
Nias and Libra Dual boilers must have the Jumper positioned in the position
F2PIA
like
an instantaneous boiler with plate heat exchanger.
