Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052 BACnet points list
Updated 12 November 2026
LEGIOMIX 2.0 is an electronic mixing valve for domestic hot water with programmable thermal disinfection and thermal shock. Through the Caleffi 755052 gateway it appears on BACnet MS/TP or BACnet IP with probe temperatures T1/T2, operating, motor and control status, ten alarm flags, I/O states, the clock, the mixing setpoint, disinfection settings and weekly schedule, recirculation time bands and start/stop/reset commands. All objects share one running ID sequence.
This page lists 85 BACnet objects for the Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052 — 53 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Caleffi’s own free documentation, linked below.

BMS integration notes: Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052
Add the Legiomix_2_0_6000_Series profile and the valve's Modbus Node-ID in the gateway, then read T1/T2, AI 7 status and the alarm BIs. Write AV 46 for the mixing setpoint and use BV 87 to reset active alarms.
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
- The gateway (a ProtoNode FPC-N54) ships with fixed Caleffi profiles; pick the profile and the device's Modbus Node-ID in its web configurator (default IP 192.168.1.24, user admin, password on the gateway label).
- The BACnet device instance is derived from the Modbus Node-ID (1-255), which must be unique per device.
- Serves BACnet MS/TP or BACnet IP; set Virtual Server Nodes to Yes when several devices share one gateway.
- Valve Modbus port: 9600 baud, 8 data bits, 1 stop bit, parity Even (factory default) or None.
Watch out for
- Temperature objects switch between °C and °F with BV 42.
- Disinfection Type (AV 47) is bit-coded; read it as a byte.

Integration notes
- The guide prints no read/write column; AI and BI objects are listed read-only and AV/BV settings and commands writable.
- If Temperature Unit (BV 42) is set to °F, temperatures are reported already converted to °F.
- There is no alarm AL02 object; IDs 48-50 are not used.
- Some names are printed with spelling errors ('Thermal Schock', 'allarms', 'istorical'); they are kept as printed.
- Not the same list as the LEGIOMIX 6000 (6001) or the LEGIOMIXevo 6003.
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. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052 and exports what it actually has to Excel — free.

Questions about the Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052
How many BACnet points does the Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052 have?
This list has 85 BACnet objects: 17 analog inputs, 29 analog values, 15 binary inputs, 24 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052 BACnet points are writable?
53 of the 85 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.
Where is the official Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052 BACnet documentation?
The source is Start-up Guide for the gateway MODBUS RTU / BACnet, Code 755052, Appendix 6 LEGIOMIX_2.0_6000_SERIES Modbus RTU mappings to BACnet (H0004703.03), revision 2024, published free by Caleffi at https://www.caleffi.com/sites/default/files/media/external-file/h0004703_EN.pdf.
What are the minimum BACnet points to integrate the Caleffi LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052?
Start with AV 46 Set Point Temperature (Mixed water setpoint); AI 3 T1 (Probe T1 temperature); AI 4 T2 (Probe T2 temperature); AI 7 Status (Status: mixing, shock or disinfection); AI 24 Motor Status (Motor stopped, opening or closing); BI 8 Alarms AL01 (Alarm AL01); BV 87 Reset active allarms (Reset active alarms).
How do I check these points on the real LEGIOMIX 2.0 6000 series (6002) mixing valve via gateway 755052?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
