OPERATING DIAGRAMS WWR-BWR MTD
The heat pump is connected directly to the central heating circuit (the minimum water
content required must be ensured).
The heat pump can also produce domestic hot water by managing a special 3-way
valve, connected to a hot water storage cylinder.

Example water circuit diagram
The heat pump heats the water in the heating system storage cylinder.
The underfloor system is managed by the central heating pump, installed externally
to the storage cylinder, and by the mixer valve (unit 12).
The heat pump can also produce domestic hot water by managing a special 3-way
valve, connected to a hot water storage cylinder.
