Description

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 two Grundfos Direct SensorsTM are connected and at least one of them measures the fl ow rate (VFS-type), the heat quantity can be calculated. The WMZG1 also monitors the operating status of the system and displays deviations.

Recording of:
Flow temperature, Return temperature, Power, Heat quantity, Flow rate, Pressure, Differential pressure, System errors.
