BCI-R™ / BCI2-R™ Configuration for Control with Automation System / 3rd Party (Voyager / Precedent / Odyssey) – Trane Commercial HVAC Help Center

BCI-R points need to be configured very specifically for BAS control

You will need to control the "Active Value" and "Out of Service" BACnet properties with one of the following tools
- Tracer TU
- Trane BACnet Setup Tool - BACnet Setup Tool - Setup UC/BCI for Integration into BAS
- BACnet Building Automation System / Front End
  
  Note
  
  There are a minimum set of points required (section "1") and some optional applications specific settings (section "2").
Unit should operate correctly in ReliaTel Test Mode before beginning.

Process

1. Configure necessary/relevant BCI-R / BCI2-R Points for System / BAS Control (required for any BAS control)

MANDATORY Point Settings for System / BAS control

You will be configuring the 1. "Out of Service" and 2. "Present Value" BACnet properties for the following points to get the unit running with a building automation system. The majority of the points below are created "Out of Service"; (aka Out of Service = ACTIVE/TRUE). You will need to make them "In Service" (aka Out of Service = INACTIVE / FALSE).

TD5 operator display must be set to "Read" mode: LCU-BCI-R-TD5-Settings-for-RTU-BAS-Control

Table 1: Mandatory settings

	Point Type / Instance	Point Name	1. "Out of Service" BACnet Property	2. Present Value (BACnet Property)
1	BO/1	System Control Command	FALSE (aka "In Service")	ACTIVE ("BAS Control")
2	BO/8	Supply Fan Configuration Command	FALSE	- ACTIVE ("Continuous") - INACTIVE ("Cycling / Auto")
3	BO/13	Filter Timer Reset	FALSE	INACTIVE
4	BO/14	Diagnostic Reset Command	FALSE	INACTIVE
5	MO/7	Occupancy Request	FALSE	1-Occupied 2-Unoccupied
6	MO/8	Heat Cool Mode Request BAS	FALSE	1-Auto 5-Cool
7	BI/1	System Control Status	FALSE	not writeable

2. Optional System Control Settings and Troubleshooting

Fan & Duct Static Pressure Control

If an RTAM board is present, unit will control to duct static when occupied and BO/8 will be ignored

Otherwise, when in service, BO/8 dictates your occupied fan operation.
