Calorimeter WMZ
Universal calorimeter module for solar and heating systems. Operation is directly carried out via the RESOL VBus®.
Graphic-display for indication of fl ow and return temperature, heat quantity,
output, flow rate and sensor faults (balance values are also stored in the case
of a power failure). Suited for solar systems with propylene-glycol-mixtures
of 0 ... 70 Vol %.
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 two Grundfos Direct Sensors™ are connected and at least one of them is a VFS type sensor, the heat quantity can be calculated. The WMZ-G1 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 - Easy connection
- Dot matrix display
- Function control
- Configurable control parameters
