Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option) BACnet points list
Updated 7 November 2026
The 38RC controller has an Ethernet port (BACnet IP, Modbus TCP) and an RS-485 port (BACnet MS/TP, Modbus RTU); BACnet is turned on and the data link chosen in the HMI Configuration > BACnet Configuration menu. The network points list has 136 objects: unit start/stop, emergency stop, demand limit and cooling setpoints, circuit pressures and temperatures, compressor relays and feedback, run hours and starts, plus points for a second air handler (AHU2) on dual-circuit units.
This page lists 136 BACnet objects for the Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option) — 27 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Carrier’s own free documentation, linked below.

BMS integration notes: Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option)
Enable BACnet in HMI Configuration > BACnet Configuration and pick IP or MS/TP as the data link, then set the unit's machine control method to Network. The BMS then starts and stops the unit (BV 4), writes demand limit and setpoints, and reads capacity, control mode and alarm state.
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 4 | A_UNIT_CHIL_S_S | Network start/stop command | Write |
| AV 2 | A_UNIT_DEM_LIM | Demand limit command (%) | Write |
| AV 5 | A_UNIT_CTRL_PNT | Control point | Write |
| BV 6 | A_UNIT_EMSTOP | Emergency stop command | Write |
| AV 8 | A_UNIT_STAT | Control mode / unit status | Read |
| AV 3 | A_UNIT_CAP_T | Percent total capacity | Read |
| AV 1008 | A_UNIT_SUPPLY_T | Supply air temperature | Write |
| MV 1 | A_UNIT_ALM | Alarm state | Read |
Enable & remote start
Set the machine control method to Network; the unit then follows CCN, BACnet (if enabled) or Modbus (if enabled) commands and ignores the remote contacts. In Local or Remote control it ignores network commands except Emergency Stop.
Sensors & values from the BMS
Return air (AV 1010), supply air (AV 1008), outdoor air (AV 1003) and space temperature (AV 2007) are listed as writable, so they can be supplied from the network when the unit is configured to use them.
Network setup
- BACnet IP uses the ETH0 (J5) port; BACnet MS/TP uses the RS-485 (J8) port.
- Path: Configuration Menu > HMI Configuration > BACnet Configuration > BACnet Data Link Layer > IP or MS/TP.
Watch out for
- Alarm routing is not supported via BACnet; poll MV 1 (alarm state) instead.
- Network commands are ignored unless the control method is Network.

Integration notes
- Access is from the ACCESS column (RO / RW). The table has no units column; temperatures and pressures follow the controller's unit setting.
- Points ending in 2 or labelled AHU2 (e.g. AV 2923 Control Point AHU2) apply to units serving two air handlers.
- Multistate values (MV 1, 3, 5, 7, 8) are printed with low/high limits only, no state texts.
- Alarm routing is not supported over BACnet according to the manual.
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 Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option) and exports what it actually has to Excel — free.

Questions about the Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option)
How many BACnet points does the Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option) have?
This list has 136 BACnet objects: 75 analog values, 56 binary values, 5 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option) BACnet points are writable?
27 of the 136 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 Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option) BACnet documentation?
The source is Gemini Select 38RCS025-050, 38RCD025-130 Commercial Air-Cooled Condensing Units - Controls, Start-Up, Operation, Service, and Troubleshooting (Appendix C, BACnet Option (IP and MS/TP), Network Points List) (38RC-3T), revision 2026-07, published free by Carrier at https://brandportal.carrier.com/asset/160e5c92-20ff-43ec-8e76-bbca78e4376c/38RC-3T.pdf.
What are the minimum BACnet points to integrate the Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option)?
Start with BV 4 A_UNIT_CHIL_S_S (Network start/stop command); AV 2 A_UNIT_DEM_LIM (Demand limit command (%)); AV 5 A_UNIT_CTRL_PNT (Control point); BV 6 A_UNIT_EMSTOP (Emergency stop command); AV 8 A_UNIT_STAT (Control mode / unit status); AV 3 A_UNIT_CAP_T (Percent total capacity); AV 1008 A_UNIT_SUPPLY_T (Supply air temperature); MV 1 A_UNIT_ALM (Alarm state).
How do I enable BMS control of the Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option)?
Set the machine control method to Network; the unit then follows CCN, BACnet (if enabled) or Modbus (if enabled) commands and ignores the remote contacts. In Local or Remote control it ignores network commands except Emergency Stop.
Can the BMS supply sensor values to the Carrier Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option)?
Return air (AV 1010), supply air (AV 1008), outdoor air (AV 1003) and space temperature (AV 2007) are listed as writable, so they can be supplied from the network when the unit is configured to use them.
How do I check these points on the real Gemini Select 38RCS/38RCD Condensing Unit (BACnet IP and MS/TP option)?
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.
