 "summary": "The SMS is a plant controller for up to four modular R-290 air-source heat pumps; it talks to the heat pumps over BACnet IP and offers BACnet IP and Modbus TCP to the BMS through the Ethernet switch in its cabinet. The object list has 315 objects grouped by function: general system commands and status, schedules, two heating/cooling zones, customer and DHW pump sets, the heat pump manager, and one block per heat pump.",

  "The heat pump n°1 to n°4 blocks are all printed in the sheet; blocks for heat pumps that are not installed stay unused.",
  "Zone 2, DHW, boiler and pump-set points only apply when those parts of the plant are configured.",
