Strato Automation OPENSTAT OS214-EH electric heat thermostat BACnet points list
Updated 12 November 2026
The OS214-EH is an electric heat version of the OS214 with BACnet MS/TP. It modulates one heating output (24 Vac pulsed on AO-1, or pulsed / 0-10 V on AO-2) from room temperature, supply temperature or both. The object list is short: room and supply setpoints, limits, proportional bands and calibration, heating demand, the supply sensor alarm and two PID loops.
This page lists 31 BACnet objects for the Strato Automation OPENSTAT OS214-EH electric heat thermostat — 20 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Strato Automation’s own free documentation, linked below.

BMS integration notes: Strato Automation OPENSTAT OS214-EH electric heat thermostat
Write the room setpoint (AV-1), and the supply setpoint (AV-2) when MSV-3 selects supply or dual control. Read room and supply temperatures, the heating demand and the supply sensor alarm.
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
- MS/TP address and baud are set in the thermostat's MSTP Config menu.
- Control type, setpoints, output type and sensor type can also be set in the Quick Setup menu.
Watch out for
- AV-18 sets the heating output used when a sensor fails.

Integration notes
- The guide has no read/write column. Access here follows its tags: Cfg, User and Cmd objects are shown writable, Status objects read-only, and BO/AO objects commandable (the guide lists them for output overrides).
- AO-1 is printed with the object name BO_1 (it is the 24 Vac pulsed output on terminal BO1).
- AV-101, AV-202 and AV-203 are marked internal use.
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 OPENSTAT OS214-EH electric heat thermostat and exports what it actually has to Excel — free.

Questions about the Strato Automation OPENSTAT OS214-EH electric heat thermostat
How many BACnet points does the Strato Automation OPENSTAT OS214-EH electric heat thermostat have?
This list has 31 BACnet objects: 3 analog inputs, 2 analog outputs, 14 analog values, 3 binary outputs, 1 binary value, 2 loops, 6 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Strato Automation OPENSTAT OS214-EH electric heat thermostat BACnet points are writable?
20 of the 31 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 Strato Automation OPENSTAT OS214-EH electric heat thermostat BACnet documentation?
The source is OS214-EH Technical User Guide, BACnet Objects, revision 2024-12-13, published free by Strato Automation at https://stratoautomation.com/wp-content/uploads/2025/01/OS214-EH-Technical-User-Guide-Dec-13-2024.pdf.
What are the minimum BACnet points to integrate the Strato Automation OPENSTAT OS214-EH electric heat thermostat?
Start with AV 1 RoomSetp (Room temperature setpoint); AV 2 Supp_SP (Supply temperature setpoint); MV 3 CtrlTyp (Control type: Intern, Supply, Dual, ExtBMS); AI 6 RoomT (Room temperature); AI 2 AI2_Supply (Supply temperature); AV 101 Htg_Dem (Heating demand, %); BV 100 SupplyTempAlarm (Supply temperature sensor alarm).
How do I check these points on the real OPENSTAT OS214-EH electric heat thermostat?
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.
