Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP) BACnet points list

Updated 6 November 2026

Short answer

Intesis interface for one Daikin Sky or VRV indoor unit (or a group run as one) on the P1P2 remote-controller bus. DIP switch SW1-5 selects BACnet MS/TP (default) or Modbus RTU. It exposes 41 fixed objects: on/off, mode, setpoint, fan and both vane directions as _command/_status pairs, error and filter signals, occupancy logic, a remote lock and a virtual-temperature function.

This page lists 41 BACnet objects for the Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP) — 19 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Intesis’s own free documentation, linked below.

BMS integration notes: Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP)

Integration in brief

Connect the gateway anywhere on the P1P2 bus, leave SW1-5 off for BACnet MS/TP, set the MAC address on SW2, then write the _command objects (on/off, mode, setpoint, fan) and read the _status objects. Several indoor units on one P1P2 bus behave as one unit.

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.

AI 2ErrorCodeWhich fault is activeRead

Enable & remote start

No enable point is documented; the gateway accepts commands once it talks to the unit. BV 2 LockRemoteControl can lock the wired remote.

Sensors & values from the BMS

Two options. With the gateway as P1P2 header (SW1-1 on), reading temperature from the remote (SW1-2 on) and the Daikin system set to use the remote's sensor, the value written to AO 1 RoomTemperature_command replaces the unit's reference temperature. Until a valid value is written the unit shows error CJ (45 on BACnet). Otherwise the Virtual Temperature function recalculates the setpoint from AO 1; BI 14 shows when it is active and AI 17 shows the BMS setpoint.

Integration notes

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 IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP)

How many BACnet points does the Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP) have?

This list has 41 BACnet objects: 10 analog inputs, 2 analog outputs, 7 analog values, 5 binary inputs, 2 binary outputs, 3 binary values, 6 multi-state inputs, 4 multi-state outputs, 2 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP) BACnet points are writable?

19 of the 41 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 Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP) BACnet documentation?

The source is IN485DAI001R000 Gateway - Daikin Sky and VRV Systems to BACnet MS/TP and Modbus RTU - User Manual, revision 2026-06-09 v1.0.20, published free by Intesis at https://www.hms-networks.com/docs/default-source/products/intesis/manuals-and-guides---manuals/user_manual_in485dai001r000.pdf.

What are the minimum BACnet points to integrate the Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP)?

Start with BO 0 OnOff_command (Start/stop the indoor unit); MO 0 Mode_command (Heat/cool/fan/dry/auto selection); AO 0 SetPoint_command (Temperature setpoint from the BMS); MO 1 FanSpeed_command (Fan speed selection); BI 0 OnOff_status (Confirm the unit is running); AI 0 SetPoint_status (Setpoint the unit is really using); AI 1 RoomTemperature_status (Room/return temperature for trending); BI 1 ErrorActive (Unit alarm); AI 2 ErrorCode (Which fault is active).

How do I enable BMS control of the Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP)?

No enable point is documented; the gateway accepts commands once it talks to the unit. BV 2 LockRemoteControl can lock the wired remote.

Can the BMS supply sensor values to the Intesis IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP)?

Two options. With the gateway as P1P2 header (SW1-1 on), reading temperature from the remote (SW1-2 on) and the Daikin system set to use the remote's sensor, the value written to AO 1 RoomTemperature_command replaces the unit's reference temperature. Until a valid value is written the unit shows error CJ (45 on BACnet). Otherwise the Virtual Temperature function recalculates the setpoint from AO 1; BI 14 shows when it is active and AI 17 shows the BMS setpoint.

How do I check these points on the real IN485DAI001R000 (Daikin Sky and VRV gateway, BACnet MS/TP)?

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.
