Kamstrup MULTICAL 403 / 603 BACnet MS/TP module (HC-003-66) BACnet points list
Updated 28 October 2026
The HC-003-66 plug-in module puts a MULTICAL 403 or 603 meter on BACnet MS/TP as a B-ASC device. It serves 41 read-only Analog Inputs (flows, temperatures, power, energy and volume registers, pulse inputs, mass) and 12 Positive Integer Values (info code, hour counters, configuration and meter numbers). The PICS units column is headed 'Most often used units' and often lists several options per object; read each object's Units property for the one in use.
This page lists 53 BACnet objects for the Kamstrup MULTICAL 403 / 603 BACnet MS/TP module (HC-003-66) — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Kamstrup’s own free documentation, linked below.

BMS integration notes: Kamstrup MULTICAL 403 / 603 BACnet MS/TP module (HC-003-66)
Give the module a unique MS/TP address and device instance, then read heat energy (AI 10), cooling energy (AI 12), power (AI 2), flow (AI 0) and the inlet and outlet temperatures (AI 3, AI 4). Watch the info code (PIV 0) for meter events. Nothing needs to be written.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Network setup
- BACnet MS/TP over RS-485, as master or slave; 9600, 19200, 38400, 57600, 76800 or 115200 baud.
- Device instance defaults to the last 5 digits of the meter number; Object_Identifier and Object_Name are writable.
- Max_Master defaults to 127 (writable only when the module runs as master); Max_Info_Frames defaults to 2.
- COV, Who-Is and Who-Has only work when the module is a master.
- No segmentation; max APDU 480 bytes.
Watch out for
- Many AIs list several possible units, some including 'No Units'; the PICS does not say which applies.
- Energy registers list Wh, kWh or MWh as possible units; check the Units property before trending.

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the MULTICAL 403 / 603 BACnet MS/TP module (HC-003-66) and exports what it actually has to Excel — free.
