 "summary": "The MPC is ClimateMaster's add-on DDC controller for water-source heat pumps. It sits on top of the CXM2/DXM2.6 unit board, acts as a thermostat with a wall sensor, and talks BACnet MS/TP, BACnet over ARC156, N2 or Modbus. The BMS commands occupancy, writes occupied and unoccupied heating and cooling setpoints (in °F or °C objects), can shut the unit down, and reads compressor, fan and temperature status plus fault counters and the lockout state. Units can share one wall sensor in a leader/follower setup.",
