Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) BACnet points list
Updated 6 November 2026
On 38APS/38APD condensing units the BACnet option is a UPC Open controller in the main control box. It talks BACnet MS/TP to the BMS and CCN to the unit's ComfortLink board. The list has about 150 objects: start/stop, emergency stop, demand limit, cooling setpoints, control mode and type, compressor and fan relays, circuit pressures and temperatures, run hours and starts, thermostat inputs and spare user values.
This page lists 149 BACnet objects for the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) — 42 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 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option)
Address the UPC Open on its rotary switches and set the BAS port DIP switches for MS/TP. Set the unit control method to CCN Control (CTRL=3); the BMS then starts and stops the unit with BV 4 chil_s_s_1 and can limit capacity with AV 2 dem_lim_1. Read the control mode (AV 8), capacity, circuit pressures and the comm 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.
| Object | Name | Why | Access |
|---|---|---|---|
| BV 4 | chil_s_s_1 | Start/stop command (CCN control only) | Write |
| AV 2 | dem_lim_1 | Active demand limit, % | Write |
| AV 5 | ctrl_pnt_1 | Control point | Write |
| MV 5 | control_msv_1 | Control method: must be CCN for BMS start/stop | Read |
| AV 8 | stat | Control mode (6 = On CCN, 2 = Off CCN) | Read |
| AV 3 | cap_t_1 | Percent total capacity | Read |
| AV 1008 | sa_temp_1 | Supply air temperature | Read |
| MV 1 | alm_msv_1 | Alarm state: Normal, Alert or Alarm | Read |
| BV 58 | comm_lost_alm | UPC Open lost CCN communication with the unit | Read |
Enable & remote start
Set the control method to CCN Control (Configuration > OPT2 > CTRL = 3); the manual says units run by a third-party BAS through the UPC Open must use it. The unit switch must be in Enable, or in Remote Control with the external contacts closed. The BMS then writes CHIL_S_S Start/Stop; EMSTOP (BV 6) stops all cooling until set back to Enable.
Heartbeat & communication loss
The manual says loss of CCN communication puts the unit in stand-alone mode. BV 58 comm_lost_alm and BV 2999 element_stat_1 show the UPC Open link to the unit.
Sensors & values from the BMS
Outside Air Temperature (AV 1003) and Space Temperature (AV 2007) are writable; the space temperature is used with the SPT control types.
Network setup
- Set the MAC address on the UPC Open Tens and Ones rotary switches; it reads switches, DIP switches and jumpers only at power-up.
- Device instance = network number (default 16101) followed by the MAC address, e.g. MAC 20 gives 1610120.
- BAS port: DS3 enable, DS4 E1-485, DS5-DS8 set to MSTP; baud on DS1-DS2 (9600, 19.2k, 38.4k or 76.8k, Carrier default 76.8k); 8N1 fixed. EIA-485 jumpers to EIA-485 and 2W.
- Fit a BT485 terminator on the first and last controller of the MS/TP segment.
- The UPC Open and the ComfortLink board must use the same CCN element and bus numbers (factory 1 and 0).
Watch out for
- Start/stop over BACnet only works with the control method set to CCN; monitoring alone does not need it.
- Points depend on unit size and options (number of compressors and fans, head pressure control, digital compressor).
- Thermostat inputs Y1-Y4 are read-only in this list.

Integration notes
- Object names end in _1, except a few printed without it (stat, oa_temp, space_temp, comm_lost_alm).
- Multistate objects (MSV) are copies of CCN points made for i-Vu and BACnet; their state numbers are printed from 0, so the device may report them +1 (BACnet multistate values start at 1). Check by discovery.
- Binary states are shown as 0/1 from the printed ON_OFF, YES_NO and ENA_DIS ranges. Numeric ranges are added to descriptions.
- Rows appear for both circuits (A and B) with the same description; the object name tells them apart.
- The 5 user-defined analog and 5 binary values are spare objects with no unit function.
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 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) and exports what it actually has to Excel — free.

Questions about the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option)
How many BACnet points does the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) have?
This list has 149 BACnet objects: 88 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 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) BACnet points are writable?
42 of the 149 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 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) BACnet documentation?
The source is 38APS/38APD 025-130 Air-Cooled Condensing Units with ComfortLink Controls Version 8 - Controls, Start-Up, Operation, Service and Troubleshooting (Appendix C, Table G Network Points List) (38AP-3T), revision 2022-08 (Rev A), published free by Carrier at https://www.shareddocs.com/hvac/docs/1005/Public/02/38AP-3T.pdf.
What are the minimum BACnet points to integrate the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option)?
Start with BV 4 chil_s_s_1 (Start/stop command (CCN control only)); AV 2 dem_lim_1 (Active demand limit, %); AV 5 ctrl_pnt_1 (Control point); MV 5 control_msv_1 (Control method: must be CCN for BMS start/stop); AV 8 stat (Control mode (6 = On CCN, 2 = Off CCN)); AV 3 cap_t_1 (Percent total capacity); AV 1008 sa_temp_1 (Supply air temperature); MV 1 alm_msv_1 (Alarm state: Normal, Alert or Alarm); BV 58 comm_lost_alm (UPC Open lost CCN communication with the unit).
How do I enable BMS control of the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option)?
Set the control method to CCN Control (Configuration > OPT2 > CTRL = 3); the manual says units run by a third-party BAS through the UPC Open must use it. The unit switch must be in Enable, or in Remote Control with the external contacts closed. The BMS then writes CHIL_S_S Start/Stop; EMSTOP (BV 6) stops all cooling until set back to Enable.
Does the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option) need a BACnet heartbeat or have a communication timeout?
The manual says loss of CCN communication puts the unit in stand-alone mode. BV 58 comm_lost_alm and BV 2999 element_stat_1 show the UPC Open link to the unit.
Can the BMS supply sensor values to the Carrier 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet option)?
Outside Air Temperature (AV 1003) and Space Temperature (AV 2007) are writable; the space temperature is used with the SPT control types.
How do I check these points on the real 38APS/38APD 025-130 Condensing Unit (ComfortLink, UPC Open BACnet 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.
