Circulating pump
The system uses a high-head, modulating pump that is suitable for use on any type of one- or two-pipe heating installation. The
automatic air vent valve built into the pump body enables fast venting of the heating system.
Operation of the pump in DHW mode —> 100% fixed.
To prevent flow noise, you must pay attention to the hydraulic design of the heating installation.
