Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) BACnet points list
Updated 4 November 2026
The MicroTech MT2300 is the controller on Daikin's R32 SmartSource heat pumps. It joins BACnet MS/TP through a separate BACnet communication module, and one object list serves both the SmartSource Series2 and the two-compressor SS2C applications. Points cover setpoints, network overrides for occupancy, mode and space temperature, water and refrigerant temperatures, fan speed, the board's configuration switches, A2L refrigerant-leak inputs and alarm codes.
This page lists 148 BACnet objects for the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) — 73 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Daikin Applied’s own free documentation, linked below.

BMS integration notes: Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH)
Commission the BACnet module (baud, MAC and instance) through its serial menu, then run the unit from the BMS with the network override objects: occupancy (MSV 7 or MSV 8), application mode (MSV 10) and compressor enable (MSV 1). Feed space temperature or a setpoint from the network if needed, and set Receive Heartbeat so overrides drop back when the BMS stops writing.
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 |
|---|---|---|---|
| MV 7 | OccManCmd | Occupancy override from the BMS | Command |
| MV 10 | ApplicMode | Application mode (Auto/Heat/Cool/Off/Fan Only/Dehumid) | Command |
| MV 1 | ComprEnable | Compressor enable, usually from loop flow proof | Command |
| AV 19 | NetworkSetpoint | Network reference setpoint | Command |
| BV 1 | ClearAlarm | Clear active fault alarms | Write |
| MV 4 | McQWSHPStatus | Unit operating state | Read |
| AV 22 | EffectSpaceTemp | Space temperature used for control | Read |
| AI 2 | LWT | Leaving water temperature | Read |
| MV 2 | CurrentAlarm | Highest-priority active alarm | Read |
Enable & remote start
No local/remote switch. The network override objects act as soon as they are written: Occupancy Override Input (MSV 7) or Occupancy Scheduler (MSV 8) set occupancy, Application Mode (MSV 10) limits the unit to Auto/Heat/Cool/Off/Fan Only/Dehumid and overrides the room sensor mode switch, and Compressor Enable (MSV 1) permits compressor operation. All revert to Null after a controller reboot.
Heartbeat & communication loss
Receive Heartbeat (AV 20, cpRcvHrtBt, 0-6553.4 s, default 0 = disabled) sets how long a supported network override may go without being rewritten before it reverts to its default; each supported override has its own timer. Send Heartbeat (AV 21) is not supported by the BACnet module; use COV instead.
Sensors & values from the BMS
Write space temperature to AV 18 and space humidity to AV 45; a network dewpoint goes to AV 51. AV 19 sets the reference setpoint only after local setpoint adjust is disabled with MSV 14 = 1. AV 35 shifts the occupied/standby setpoints, MSV 9 takes a network occupancy sensor, MSV 16 overrides the humidistat and MSV 3 the fan On/Auto switch.
Network setup
- Device instance is System Minimum Instance (AV 412, default 3101000) plus the MS/TP MAC address.
- Baud (default 38400) and Max Masters are set from the module's serial menu: DB-9 port, 19200 bps 8-N-1, null-modem cable; press S to save.
- With address switch S3 at 255 (factory default) the MAC is acquired during commissioning and can then be changed through AV 411; any other S3 value is used as a fixed MAC.
- Max APDU length is fixed at 480.
Watch out for
- cp... configuration objects are written to flash; do not write them cyclically.
- Network overrides revert to Null on reboot, so the BMS must restore them.
- Changing Units (MSV 15) from English to Metric changes the temperature values the BMS reads.
- An A2L refrigerant leak or loss of A2L board power puts the unit into an alarm state.

Integration notes
- Configuration objects (names starting with cp) are stored in flash; the guide warns that repeated writes wear it out.
- Network override objects (access C) revert to their default (Null) after a controller reboot.
- BI 15-34 report the baseboard and I/O expansion module configuration switches; some switches mean different things on Series2 and SS2C units.
- AV 411 is named MacAddress (writable) when address switch S3 is at 255, otherwise MacAddressSwitch (read-only).
- MV 2 and MV 5 return the alarm numbers from the guide's alarm table (1-28).
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 MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH)
How many BACnet points does the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) have?
This list has 148 BACnet objects: 10 analog inputs, 65 analog values, 35 binary inputs, 12 binary outputs, 1 binary value, 5 multi-state inputs, 20 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) BACnet points are writable?
73 of the 148 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 Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) BACnet documentation?

What are the minimum BACnet points to integrate the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH)?
Start with MV 7 OccManCmd (Occupancy override from the BMS); MV 10 ApplicMode (Application mode (Auto/Heat/Cool/Off/Fan Only/Dehumid)); MV 1 ComprEnable (Compressor enable, usually from loop flow proof); AV 19 NetworkSetpoint (Network reference setpoint); BV 1 ClearAlarm (Clear active fault alarms); MV 4 McQWSHPStatus (Unit operating state); AV 22 EffectSpaceTemp (Space temperature used for control); AI 2 LWT (Leaving water temperature); MV 2 CurrentAlarm (Highest-priority active alarm).
How do I enable BMS control of the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH)?
No local/remote switch. The network override objects act as soon as they are written: Occupancy Override Input (MSV 7) or Occupancy Scheduler (MSV 8) set occupancy, Application Mode (MSV 10) limits the unit to Auto/Heat/Cool/Off/Fan Only/Dehumid and overrides the room sensor mode switch, and Compressor Enable (MSV 1) permits compressor operation. All revert to Null after a controller reboot.
Does the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH) need a BACnet heartbeat or have a communication timeout?
Receive Heartbeat (AV 20, cpRcvHrtBt, 0-6553.4 s, default 0 = disabled) sets how long a supported network override may go without being rewritten before it reverts to its default; each supported override has its own timer. Send Heartbeat (AV 21) is not supported by the BACnet module; use COV instead.
Can the BMS supply sensor values to the Daikin Applied MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH)?
Write space temperature to AV 18 and space humidity to AV 45; a network dewpoint goes to AV 51. AV 19 sets the reference setpoint only after local setpoint adjust is disabled with MSV 14 = 1. AV 35 shifts the occupied/standby setpoints, MSV 9 takes a network occupancy sensor, MSV 16 overrides the humidistat and MSV 3 the fan On/Auto switch.
How do I check these points on the real MicroTech MT2300 WSHP Controller - SmartSource R32 (SCH/SDH, SMH/SNH, SSH/STH)?
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.
