With the standard built-in pressure sensor
replaced by a pressure switch, pressure
may go up to 6.0 bar. Parameter P4AD
needs to be changed.

230 Vac is necessary for the boiler to func-
tion. If a 400 Vac boiler pump is applied, 400
Vac must be connected to the appliance so
the power supply for the pump can be deliv-
ered by the system. (An optional safety
switch for the pump motor must be added ex-
ternally).
