Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) BACnet points list

Updated 4 November 2026

Short answer

The TEC26x6(H)-2 is the earlier generation of the TEC fan coil thermostat on BACnet MS/TP. Its instance numbers differ from the later TEC26x6(H)-4. The list covers system mode, fan mode, occupancy, occupied/unoccupied setpoints, loop demands, auxiliary output, valve and fan status, input status, alarms and configuration; humidity objects exist only on the TEC2636 and TEC2656 models.

This page lists 54 BACnet objects for the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) — 33 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Johnson Controls’s own free documentation, linked below.

BMS integration notes: Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP)

Integration in brief

Address the thermostat on the BACnet MS/TP trunk, then command System Mode (MV 13) and Occupancy (MV 12) and Fan Mode (MV 14) and write the occupied setpoints (AV 49/50). Read Room Temp, Fan Status and the filter and service 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.

Enable & remote start

Occupancy (MV 12) set to Occupied, Unoccupied or Temporary Occupied overrides the thermostat; Resume Schedule hands occupancy back. System Mode (MV 13) can switch the unit off.

Heartbeat & communication loss

All network overrides are released automatically after 10 minutes without communication to any other device (for example if the network cable is removed). Keep the thermostat on an active trunk and rewrite overrides if needed.

Sensors & values from the BMS

To supply room temperature from the BAS, set Room Temp Override (BV 7) to Override and write Room Temp (AV 6). Outdoor Temperature (AV 8) is only valid when it is written over the network.

Integration notes

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 TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP)

How many BACnet points does the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) have?

This list has 54 BACnet objects: 1 analog input, 15 analog values, 8 binary inputs, 12 binary values, 18 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) BACnet points are writable?

33 of the 54 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 Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) BACnet documentation?

The source is TEC26x6(H)-2 Series BACnet MS/TP Networked Thermostats with Two Outputs, Dehumidification Capability, and Three Speeds of Fan Control Installation Instructions (Part No. 24-9890-234, Rev. B), revision 2009-08-31, published free by Johnson Controls at https://docs.johnsoncontrols.com/bas/api/khub/documents/aVSH2~9AAx64nsxh7qXAdA/content.

What are the minimum BACnet points to integrate the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP)?

Start with MV 13 System Mode (System mode: off, cool, heat or auto); MV 12 Occupancy (Occupancy command from the BAS); MV 14 Fan Mode (Fan mode; states follow Fan Mode Sequence); AV 49 Occupied Heat Setpoint (Occupied heating setpoint, °F); AV 50 Occupied Cool Setpoint (Occupied cooling setpoint, °F); AV 6 Room Temp (Room temperature, °F); MV 68 Fan Status (Fan speed status); BI 59 Filter Alarm (Filter alarm); BI 60 Service Alarm (Service alarm).

How do I enable BMS control of the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP)?

Occupancy (MV 12) set to Occupied, Unoccupied or Temporary Occupied overrides the thermostat; Resume Schedule hands occupancy back. System Mode (MV 13) can switch the unit off.

Does the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?

All network overrides are released automatically after 10 minutes without communication to any other device (for example if the network cable is removed). Keep the thermostat on an active trunk and rewrite overrides if needed.

Can the BMS supply sensor values to the Johnson Controls TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP)?

To supply room temperature from the BAS, set Room Temp Override (BV 7) to Override and write Room Temp (AV 6). Outdoor Temperature (AV 8) is only valid when it is written over the network.

How do I check these points on the real TEC26x6(H)-2 Series Fan Coil Thermostat with Dehumidification and Three Fan Speeds (BACnet MS/TP)?

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.
