Multistack Compu25 - Can you show me a sample points list for a heat pump?

The Multistack COMPU25 is a high-performance controller used in modular heat pump systems. Successful integration into a Building Automation System (BAS) requires a complete and explicit Points List to ensure every data register is mapped accurately for monitoring and control.

This technical resource provides the full, unabridged list of 200 Analog Values (Av) and 34 Binary Values (Bv). Using this explicit data helps prevent integration errors and ensures your gateway or BMS is polling the correct addresses.

Explicit Multistack COMPU25 Heat Pump Points List (Full)

The following table contains the complete set of data points available for the Multistack COMPU25. Addresses follow standard 1-based indexing for FieldServer and CAS integration tools.

Integration Best Practices

  • Always verify the specific firmware version of your Multistack controller, as point mapping can shift between releases.
  • Ensure your gateway is configured to distinguish between Analog Values (Av) and Binary Values (Bv), even if they share the same numeric address.
  • Monitor the Current Faults register to trigger alerts in your BMS for proactive system maintenance.
  • Use CAS Modbus Scanner or CAS BACnet Explorer to verify point data before finalizing your integration.
