This boiler is able to operate in different conditions:
CASE A - only heating
CASE B - only heating with external water tank connected, managed by a thermostat, to prepare domestic hot water
CASE C - only heating with external water tank connected, managed by a temperature sensor (kit available upon request), to prepare domestic hot water.
Depending on the type of installation selected, it is necessary to set the parameter "domestic hot water mode". This operation must be performed by a
Technical Service Centre when starting-up the boiler.
