PM Controllers (Valves)

Whenever there is a call for DHW, the PM valve diverts the primary flow through the heat exchanger to generate DHW, using all available energy to support the DHW demand.

Differential Pressure Valves

The balancing and shut-off valve Kombi-3-plus BLUE is suitable for the return. The valve provides automatic regulation of the differential pressure by means of a diaphragm controller without draining the system.

Thermostatic Head & Valve Body

The temperature of the DHW is controlled by a thermostatic head with an immersion sensor, this head controls the temperature of the hot water that exits the heat exchanger and regulates the primary water flowrate.
