Boiler connection
Mono bloc
This is an application that connects the boiler to the Mono bloc, to compensate for insufficient capacity by operate
boiler when outdoor temperature drops & heat pump capacity is insufficient.
Boiler is connected parallel with heat pump against heating circuit.
There are 3 modes selectable by remote controller for boiler connection.
Besides that, an application that connects to the DHW tank's circuit to heat up tank's hot water is also possible.
(Operation setting of boiler shall be responsible by installer.)
This system requires optional PCB (CZ-NS4P).
Depending on the settings of the boiler, it is recommended to install buffer tank as temperature of circulating water
may get higher. (It must connect to buffer tank especially when selecting Advanced Parallel setting.)

Make sure the boiler and its integration in the system complies with applicable legislation.
Make sure the return water temperature from the heating circuit to the Mono bloc does NOT exceed 55°C.
