Example: Constant differential temperature

Disadvantages of conventional wiring/control

  • Analogue data items
  • Temperature controlled centrally in the building management system
  • Required accessories per pump:
    2 x temperature sensor

System information:

  • Pump on/off, feedback missing
  • Collective fault signal
  • Feed temperature
  • Return temperature
  • Hours of operation, derived

Disadvantages of conventional cabling

  • Lots of cabling work and additional costs
  • Analogue control parameters have to be entered separately (e.g. temperature)
  • Star-connected wiring of fault and run signals
  • High degree of wear due to frequent activation and deactivation of the pumps

Advantages of bus-compatible cabling/control

  • Digital data items
  • Temperature controlled decentrally in the pump
  • Required accessories per pump:
    1 x temperature sensor PT1000-AA, 1 x Wilo CIF module

System information

  • Volume flow
  • Delivery head
  • Operating hours
  • Feed temperature
  • Return temperature
  • Digital inputs
  • Operating status of the system
  • Heating/cooling quantity
  • Fault and run signals including index

Advantages of bus-capable cabling:

  • Considerably less cabling work and costs
  • Low fire load because of simple cabling
  • Decentral control within the pumps
  • High energy savings due to needs-based control of the pumps
  • Digital processing of data items and queries for virtual data item (e.g. heating/cooling quantity)
  • One language between the building management system and all pumps
  • Simple commissioning, modular and decentral, via the pump display
