Kemper KHS BACnet Gateway L / XL for MASTER 2.0/2.1 BACnet points list
Updated 6 November 2026
BACnet IP gateway (MS/TP optional) for the Kemper KHS MASTER 2.0/2.1 drinking-water hygiene controller. It exposes system objects (restart, mode, clock, SD-card logging, software version) and one block per MASTER/SLAVE device with temperature, flow, volume, cycle count, manual valve mode, error acknowledge and leak/backflow/flow alarms.
This page lists 31 BACnet objects for the Kemper KHS BACnet Gateway L / XL for MASTER 2.0/2.1 — 11 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Kemper’s own free documentation, linked below.

BMS integration notes: Kemper KHS BACnet Gateway L / XL for MASTER 2.0/2.1
Set the IP or MS/TP settings on the gateway web server, then read each device block (temperature, flow, alarms) and use the MASTER system objects for mode and clock. Acknowledge latched errors with BV x25.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| MV 102 | Mode | System mode (1 = locked, 2 = P1, 3 = P2) | Write |
| MV 124 | Manual mode | Automatic or manual valve operation | Write |
| BV 125 | Acknowledge error | Group error; write to acknowledge | Write |
| BI 137 | Open Valve | Valve open status | Read |
| AI 120 | Current temperature | Water temperature, °C | Read |
| AI 121 | Current flow | Flow, L/min | Read |
| BI 133 | Leak pending | Leak alarm | Read |
| BI 127 | Backflow pending | Backflow alarm | Read |
| BI 130 | Communication failure Bus A | MASTER bus A comm failure | Read |
Network setup
- Default gateway IP 10.1.23.151 / 255.255.255.0, gateway 10.1.23.1.
- Network number, UDP port, IP mode, MS/TP address and baud rate are set on the gateway web server.
- Software version V2.20 or later (as stated on the list).
Watch out for
- While MV 109 is creating a file the MASTER does not answer requests; MV 109 returns to 0 when done.
- Manual modes 5 and 6 follow the valve sequence and waiting times.

Integration notes
- System objects (BV 101 to AI 140) exist once, in the MASTER.
- Device objects repeat for up to 62 devices: the hundreds digit is the device (1xx = MASTER, 2xx = SLAVE 1, 3xx = SLAVE 2 ...). The MASTER block is shown; BI 232 is printed in its SLAVE 1 form.
- Names are the list's data point labels. Units and other object details can be read from the EDE file the gateway creates.
- Read/write objects use data points of Gateway 2 (per the document).
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 KHS BACnet Gateway L / XL for MASTER 2.0/2.1 and exports what it actually has to Excel — free.

Where is the official Kemper KHS BACnet Gateway L / XL for MASTER 2.0/2.1 BACnet documentation?
The source is Data Point List - KHS BACnet Gateway L / XL for MASTER 2.0|2.1 (dok_tin_me120090), revision 05.2022, published free by Kemper at https://www.kemper-group.com/media/global-media/pim-daten/dok/tin/dok_tin_me120090_sall_ain_v100.pdf.
What are the minimum BACnet points to integrate the Kemper KHS BACnet Gateway L / XL for MASTER 2.0/2.1?
Start with MV 102 Mode (System mode (1 = locked, 2 = P1, 3 = P2)); MV 124 Manual mode (Automatic or manual valve operation); BV 125 Acknowledge error (Group error; write to acknowledge); BI 137 Open Valve (Valve open status); AI 120 Current temperature (Water temperature, °C); AI 121 Current flow (Flow, L/min); BI 133 Leak pending (Leak alarm); BI 127 Backflow pending (Backflow alarm); BI 130 Communication failure Bus A (MASTER bus A comm failure).
How do I check these points on the real KHS BACnet Gateway L / XL for MASTER 2.0/2.1?
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.
