Bosch REGO 5200 heat pump controller (Supraeco T) BACnet points list
Updated 12 November 2026
Short answer
The REGO 5200 heat pump controller publishes one BACnet device (instance 2001) with about 250 objects: heat curve and DHW settings, communicated (override) sensor values and setpoints as AVs, sensor readings and run-time meters as AVs, compressor and pump commands/statuses and I/O as BVs, and one Multi-state Value per alarm. The same data is also on Modbus.
This page lists 249 BACnet objects for the Bosch REGO 5200 heat pump controller (Supraeco T) — 57 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Bosch’s own free documentation, linked below.

BMS integration notes: Bosch REGO 5200 heat pump controller (Supraeco T)
Integration in brief
Keep the third-party watchdog alive with BV 4, use BV 1-3 to allow or force the compressors, and write the communicated flow setpoint or sensor values when override mode is used. Read sensor values, compressor run states and the summary 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.
| Object | Name | Why | Access |
|---|---|---|---|
| BV 1 | externalCompressorStartEnable | Third-party compressor start (0 Auto, 1 Run) | Write |
| BV 2 | externalStartCompressor1 | Compressor 1 allow (0 Stop, 1 Auto) | Write |
| AV 35 | flowTemperatureSetpointCom | Flow temperature setpoint, communicated mode | Write |
| BV 4 | resetWatchdog | Third-party watchdog reset (5 min) | Write |
| MV 16 | compressor1RunState | Compressor 1 run state | Read |
| AV 70 | sensorT0 | Heating system temperature T0 | Read |
| AV 72 | sensorTL1 | Outdoor temperature (damped) | Read |
| BV 10 | sumAlarmA | Summary alarm A | Read |
| BV 11 | sumAlarmB | Summary alarm B | Read |
Enable & remote start
BV 1 (externalCompressorStartEnable) and BV 2/BV 3 (allow per compressor) let a third-party system start or block the compressors.
Heartbeat & communication loss
BV 4 resetWatchdog is the third-party watchdog reset (5 minutes); the Modbus part of the manual says watchdog-dependent settings are ignored unless the watchdog has been reset.
Sensors & values from the BMS
BV 5 (CommunicatedSensors) switches T0 and TL1 to the values written to AV 3/AV 4; TW1 uses AV 5 when the TW1 sensor setting is Communicated. BV 6 (communicatedFlowTempSetpoint) makes the controller use the flow setpoint written to AV 35.
Network setup
- BACnet device instance is printed as 2001.
Watch out for
- MV 2 (AlaAcknow) and AV 2 (alarmAcknowledge) acknowledge alarms by writing the alarm number.

Integration notes
- The manual does not say which BACnet data link (IP or MS/TP) the controller uses; the Modbus side is Modbus TCP.
- Object types are printed as BACnet type numbers (2 = AV, 5 = BV, 19 = MSV).
- Access comes from the printed 'settable' column (Y = writable).
- Units are not printed; temperatures and setpoints follow the controller's units.
- Each alarm (Alarm1-Alarm105) is its own MSV (instances 19-123); alarm numbers are not continuous (e.g. no Alarm92).
- Instance gaps (AV 46-63, AV 66, MSV 4-9) are as printed.
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 REGO 5200 heat pump controller (Supraeco T) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Bosch REGO 5200 heat pump controller (Supraeco T)
How many BACnet points does the Bosch REGO 5200 heat pump controller (Supraeco T) have?
This list has 249 BACnet objects: 104 analog values, 34 binary values, 111 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Bosch REGO 5200 heat pump controller (Supraeco T) BACnet points are writable?
57 of the 249 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.
Where is the official Bosch REGO 5200 heat pump controller (Supraeco T) BACnet documentation?
The source is Modbus/ Bacnet protocol REGO 5200 (6 720 821 165), revision 2016/11, published free by Bosch at https://www.bosch-homecomfort.com/ocsmedia/optimized/full/o451341v272_Modbus-Protokoll_Supraeco_T-2.pdf.
What are the minimum BACnet points to integrate the Bosch REGO 5200 heat pump controller (Supraeco T)?
Start with BV 1 externalCompressorStartEnable (Third-party compressor start (0 Auto, 1 Run)); BV 2 externalStartCompressor1 (Compressor 1 allow (0 Stop, 1 Auto)); AV 35 flowTemperatureSetpointCom (Flow temperature setpoint, communicated mode); BV 4 resetWatchdog (Third-party watchdog reset (5 min)); MV 16 compressor1RunState (Compressor 1 run state); AV 70 sensorT0 (Heating system temperature T0); AV 72 sensorTL1 (Outdoor temperature (damped)); BV 10 sumAlarmA (Summary alarm A); BV 11 sumAlarmB (Summary alarm B).
How do I enable BMS control of the Bosch REGO 5200 heat pump controller (Supraeco T)?
BV 1 (externalCompressorStartEnable) and BV 2/BV 3 (allow per compressor) let a third-party system start or block the compressors.
Does the Bosch REGO 5200 heat pump controller (Supraeco T) need a BACnet heartbeat or have a communication timeout?
BV 4 resetWatchdog is the third-party watchdog reset (5 minutes); the Modbus part of the manual says watchdog-dependent settings are ignored unless the watchdog has been reset.
Can the BMS supply sensor values to the Bosch REGO 5200 heat pump controller (Supraeco T)?
BV 5 (CommunicatedSensors) switches T0 and TL1 to the values written to AV 3/AV 4; TW1 uses AV 5 when the TW1 sensor setting is Communicated. BV 6 (communicatedFlowTempSetpoint) makes the controller use the flow setpoint written to AV 35.
How do I check these points on the real REGO 5200 heat pump controller (Supraeco T)?
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.
