Daikin intelligent Touch Manager (iTM) BACnet Server Gateway DCM014A51 - Outdoor Unit Objects BACnet points list
Updated 28 October 2026
With the DCM014A51 option, each VRV outdoor unit appears behind the iTM's BACnet virtual router as its own virtual device. Common points report communication, mode, alarm, defrost, oil return, calculated power and current and outdoor air temperature, and up to three modules (main, sub-1, sub-2) add read-only refrigerant pressures, temperatures, compressor speeds, fan step and expansion valve positions.
This page lists 75 BACnet objects for the Daikin intelligent Touch Manager (iTM) BACnet Server Gateway DCM014A51 - Outdoor Unit Objects — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Daikin’s own free documentation, linked below.

BMS integration notes: Daikin intelligent Touch Manager (iTM) BACnet Server Gateway DCM014A51 - Outdoor Unit Objects
Outdoor units are read-only virtual devices behind the iTM; map communication, alarm, mode and defrost status plus the module data you need. Only modules that exist on the system (main, sub-1, sub-2) generate objects.
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 |
|---|---|---|---|
| MI 2 | Operation Mode | Cool/Heat/Fan/Heat & Cool | Read |
| BI 4 | Defrost Mode | Defrost active | Read |
| AI 9 | Outdoor Air Temperature | Ambient temp sensed at the outdoor unit | Read |
| AI 6 | Electric Power (calculated) | Outdoor unit power draw, kW (calculated) | Read |
| BI 1 | Communication Status | Outdoor unit communication alarm | Read |
| BI 3 | Outdoor Unit Alarm Status | Outdoor unit alarm with error code | Read |
Network setup
- Recommended outdoor unit device ID is 53PT (P = port 1-8, T = outdoor unit tag, e.g. 5311 for CU-1).
Watch out for
- Objects are only generated for data the outdoor unit actually provides; single-module systems have no S1_/S2_ objects.
- Values are rounded to a fixed number of significant digits; temperature units follow the iTM locale.

Integration notes
- All outdoor unit objects are read-only.
- Objects are only generated for data the outdoor unit actually has; a single-module system has no S1_ or S2_ objects.
- Temperature units follow the iTM regional setting (Celsius or Fahrenheit); pressure and power units are not stated in the guide.
- Outdoor unit devices are separate from indoor unit devices, so instance numbers can overlap with the indoor list.
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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the intelligent Touch Manager (iTM) BACnet Server Gateway DCM014A51 - Outdoor Unit Objects and exports what it actually has to Excel — free.
