Over-temperature
of water on system
return
The water that returns to the boiler from the heating system is too
hot: this may be an effect of a malfunction of the system, and any-
way this can cause a too high temperature of the flue and damage
the flue system. Before this happens, a suitable safety protection
has triggered.
Wait 20-30 minutes to let the boiler and the system cool down, then
turn the knob
on the unlock
position until the red lamp
turns off, then bring again the knob in the previous position. It is
impossible to restart the boiler before the cooling of the system. If
the block happens again, please call a qualified technician.
