controller MSR -> MODBUS RTU
MSR series controllers for recuperators are communicating their own transmission protocol.
Therefore, it was necessary to design a "converter", which would allow for direct connection of a controller to BMS
network (smart home). Converter allows you to view the following parameters of the controller:
All parameters are read function "Read Holding Register 0x03"
- temperature Tz-external
- temperature Tg - GHE
- temperature "exhaust air" Tw
- temperature Tn - supply and regulate the heating temperature
- current fan speed
- opening level of the secondary heater 0-100%
- state relays (GHE, BYPASS)
- digital input state
