Trane ReliaTel BCI-R - touch-screen zone sensor points BACnet points list
Updated 6 November 2026
This short list shows which ReliaTel BCI-R objects the Trane commercial touch-screen programmable zone sensor reads and overrides on single-zone packaged units. It covers space temperature, setpoints and offset, heat/cool mode request and status, occupancy request, fan mode, economizer enable setpoints and the BAS control flag. The sensor and BCI-R talk BACnet MS/TP.
This page lists 14 BACnet objects for the Trane ReliaTel BCI-R - touch-screen zone sensor points — 11 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Trane’s own free documentation, linked below.

BMS integration notes: Trane ReliaTel BCI-R - touch-screen zone sensor points
Use the BMS mainly for monitoring and alarms when the touch-screen sensor runs the unit. The sensor owns occupancy, mode, fan and setpoint commands; read mode status and fan speed, and only write Space Temperature BAS (priority 5 or higher) if the BMS must supply space temperature.
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 |
|---|---|---|---|
| MO 7 | Occupancy Request | Occupancy request (1=Occ, 2=Unocc, 3=Bypass, 4=Standby) | Write |
| MO 8 | Heat Cool Mode Request BAS | Heat/cool mode request (1=Auto) | Write |
| BO 8 | Supply Fan Configuration Command | Fan mode: Inactive = Auto, Active = On | Write |
| AO 2 | Space Temperature Setpoint BAS | Space temperature setpoint | Write |
| AO 11 | Space Temperature BAS | Space temperature in use by the unit | Write |
| MI 19 | Heat Cool Mode Status BAS | Actual heat/cool mode | Read |
| AI 7 | Supply Fan Speed Status | Supply fan speed, % | Read |
Enable & remote start
BO 1 System Control Command defaults to Inactive (standalone); the sensor writes Active (BAS control) at power-up. The sensor then holds the occupancy, mode, fan and setpoint objects Out_Of_Service and writes them at priority 7. The guide recommends leaving control with the sensor.
Sensors & values from the BMS
Space Temperature BAS normally comes from the sensor; a BMS can command it at priority 5 or higher (priority 6 is reserved for minimum on/off). Space Temperature Local is the unit's hard-wired sensor.
Network setup
- The sensor talks BACnet MS/TP only; default baud 76800 (leave the default).
- Sensor and unit controller should share an MS/TP link where possible to reduce communication loss.
- Trane best practice device ID: MS/TP network number followed by the MAC address (e.g. network 11, MAC 001 = 11001).
- Needs ReliaTel RTRM software 19.2 or later and BCI-R software 6.0 or later.
Watch out for
- The sensor holds these points Out_Of_Service and writes them at priority 7; a BMS writing the same points will fight the sensor.
- BO 1 does not need periodic refresh; the sensor writes it once at power-up.

Integration notes
- This is a SUBSET: only the BCI-R objects the touch-screen zone sensor uses (Table 4 of BAS-SVP080A, p15). The full BCI-R list is a separate entry (BCI-R ReliaTel).
- Access is inferred: the doc has no read/write column. Output and multistate-output objects the sensor writes are shown as W; inputs as R.
- The sensor sets Out_Of_Service on most of these objects at power-up and writes them at priority 7. AO 41/AO 42 Out_Of_Service is set from the sensor setup menu (In Use / Not Used) and should be written only once, not refreshed.
- AO 30 on ReliaTel is the standby offset (occupied offset plus shed offset, max 10 °F); the guide uses it because the BCI-R occupied offset object is limited to 5 °F.
- Matching sensor objects (AV 100, AV 44, AV 43, MV 140, MV 16, MV 112, MI 33, MV 17, AV 260, AV 261) belong to the sensor itself. Multiple-zone units (RTAM board) are not supported.
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 ReliaTel BCI-R - touch-screen zone sensor points and exports what it actually has to Excel — free.

Questions about the Trane ReliaTel BCI-R - touch-screen zone sensor points
How many BACnet points does the Trane ReliaTel BCI-R - touch-screen zone sensor points have?
This list has 14 BACnet objects: 2 analog inputs, 7 analog outputs, 2 binary outputs, 1 multi-state input, 2 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Trane ReliaTel BCI-R - touch-screen zone sensor points BACnet points are writable?
11 of the 14 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 Trane ReliaTel BCI-R - touch-screen zone sensor points BACnet documentation?
The source is Touch Screen Programmable Zone Sensor Integration Guide (Tracer UC400-B, Symbio 400-B/500/700/800, ReliaTel) (BAS-SVP080A-EN), revision 2023-08, published free by Trane at https://elibrary.tranetechnologies.com/public/commercial-hvac/Literature/Integration/BAS-SVP080A-EN_08302023.pdf.
What are the minimum BACnet points to integrate the Trane ReliaTel BCI-R - touch-screen zone sensor points?
Start with MO 7 Occupancy Request (Occupancy request (1=Occ, 2=Unocc, 3=Bypass, 4=Standby)); MO 8 Heat Cool Mode Request BAS (Heat/cool mode request (1=Auto)); BO 8 Supply Fan Configuration Command (Fan mode: Inactive = Auto, Active = On); AO 2 Space Temperature Setpoint BAS (Space temperature setpoint); AO 11 Space Temperature BAS (Space temperature in use by the unit); MI 19 Heat Cool Mode Status BAS (Actual heat/cool mode); AI 7 Supply Fan Speed Status (Supply fan speed, %).
How do I enable BMS control of the Trane ReliaTel BCI-R - touch-screen zone sensor points?
BO 1 System Control Command defaults to Inactive (standalone); the sensor writes Active (BAS control) at power-up. The sensor then holds the occupancy, mode, fan and setpoint objects Out_Of_Service and writes them at priority 7. The guide recommends leaving control with the sensor.
Can the BMS supply sensor values to the Trane ReliaTel BCI-R - touch-screen zone sensor points?
Space Temperature BAS normally comes from the sensor; a BMS can command it at priority 5 or higher (priority 6 is reserved for minimum on/off). Space Temperature Local is the unit's hard-wired sensor.
How do I check these points on the real ReliaTel BCI-R - touch-screen zone sensor points?
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.
