1 - DHW priority valve
2 - Manual by-pass
3 - 40 kW brazed heat exchanger
The DHW priority valve (1) controls
priority of the production of domestic hot
water in the presence of a DHW circuit
demand.
The heating circuit is always active when
there is no DHW tapping; we recommend
the use of a zone valve or thermostatic
valve on the heating circuit.
