Kemper KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations) BACnet points list
Updated 12 November 2026
The KTS BACnet Gateway connects Kemper KTS fresh-water (potable hot water) stations to a BMS over BACnet IP; it also offers Modbus RTU. It exposes the system's thermal disinfection controls, the hot water setpoint and device clock, buffer and circulation temperatures, and for each of up to 8 cascaded stations the temperatures, flow, primary pump output, faults and operating mode.
This page lists 46 BACnet objects for the Kemper KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations) — 13 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 KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations)
Map the station operating mode (BV x27), hot water setpoint (AV 100) and the per-station temperatures, then the common fault and coded fault per station. Thermal disinfection is started and cancelled through BV 5, with its status on MI 6. Scale temperatures by 0.1.
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.

Enable & remote start
Each station's BV x27 Betriebsart sets it to off (0) or automatic (1).
Network setup
- Physical interfaces: Ethernet (BACnet IP) and RS485 (Modbus RTU, 9600 / 8 / N / 1).
- The device clock can be set through AV 101-106.
Watch out for
- Values are scaled integers: divide temperatures and flow by 10, firmware version by 100.
- Thermal disinfection points only read once the function is enabled in the controller.
- The station 2 relay numbering (R1, R2) differs from the single-unit block (R3, R4).

Integration notes
- Point list is in German; object names are kept as printed and descriptions are English.
- Per-station objects are printed as ranges, for example AI-108 … AI-808: the hundreds digit is the station number (1-8). Only the station 1 instances are listed; add 100 per station.
- Temperatures and the setpoints are sent as °C x10 and flow as l/min x10.
- BI 13-AI 33 are for a single (non-cascade) unit and BI 213-AI 231 for station 2, as printed.
- Thermal disinfection must be enabled in the controller, otherwise AV 2-MI 6 cannot be read.
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 KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations) and exports what it actually has to Excel — free.

What are the minimum BACnet points to integrate the Kemper KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations)?
Start with BV 127 Betriebsart (Station 1 mode, 0 = off, 1 = auto (BV 227-827 others)); AV 100 Temperatur PWH Soll (Hot water setpoint, °C x10); BV 5 Starten / abbrechen (Thermal disinfection, 1 = start, 0 = cancel); AI 109 S2 - PWH Temperatur (Station 1 hot water outlet temp, °C x10); AI 117 V - PWH Volumenstrom (Station 1 hot water flow, l/min x10); MI 6 Status (Thermal disinfection status); BI 125 Sammelstörung (Station 1 common fault; write 0 to acknowledge); AI 126 Codierte Fehlermeldung (Station 1 bit-coded fault messages); BI 1 Kommunikationsstörung zum Regler (Gateway lost communication with the controller).
How do I enable BMS control of the Kemper KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations)?
Each station's BV x27 Betriebsart sets it to off (0) or automatic (1).
How do I check these points on the real KTS BACnet Gateway Fig. 916 02 022 (KTS hot water stations)?
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.
