Function description The M-bus modules (WZU-MB, WZU-MB-G4, and WZU-MI) are used by the meter to communicate with an M-bus central unit to transmit measured values. For the WZU-MB, the scope of data can be preset with a jumper. With the 2 M-bus modules, the secondary address is identical for both modules. It can be adjusted on the device using the module on slot 1 or via M-bus. The data on the M-bus module is refreshed every 15 minutes. Using the UltraAssist software, a shorter sampling cycle can be set on the WZU-MB-G4 and WZU-MI. The modules are available in 3 different versions:WZU-MBM-bus module for heat and heat/cooling energy meters, generation 2, recommended up to firmware 5.14 as per EN 1434-3WZU-MB-G4M-bus module for heat and heat/cooling energy meters, generation 4, recommended as of firmware 5.15 per EN 1434-3WZU-MIM-bus module with 2 pulse inputs for heat and heat/cooling energy meters, generation 4, recommended as of firmware 5.15 per EN 13757 and EN 1434-3NOTICE
