WMZ-G1

The WMZ-G1 is a measurement and display unit for solar thermal systems and conventional heating systems. It is possible to connect up to two Grundfos Direct Sensors™, which measure the temperature as well as one additional value - depending on the type: flow rate, relative or differential pressure. If at least one of the sensors measures the flow rate, the heat quantity can be calculated. the WMZ-G1 also monitors the operating status of the system and displays deviations.
