ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer) BACnet points list
Updated 11 November 2026
The MPC is ClimateMaster's add-on DDC controller for water-source heat pumps. It sits on top of the CXM2/DXM2.6 unit board, acts as a thermostat with a wall sensor, and talks BACnet MS/TP, BACnet over ARC156, N2 or Modbus. The BMS commands occupancy, writes occupied and unoccupied heating and cooling setpoints (in °F or °C objects), can shut the unit down, and reads compressor, fan and temperature status plus fault counters and the lockout state. Units can share one wall sensor in a leader/follower setup.
This page lists 123 BACnet objects for the ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer) — 68 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from ClimateMaster’s own free documentation, linked below.

BMS integration notes: ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer)
Address the MPC with the rotary switches and set the MS/TP baud with the DIP switches. Command occupancy with BV 12 (or a BMS schedule on BV 14) and write the occupied cooling and heating setpoints. Use BV 8 for an emergency stop and BV 4 to clear a lockout. Monitor fan and compressor status, space temperature, the Alarm State and the Fault text.
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 12 | Occupied Mode | Occupancy command (ON = occupied) | Write |
| BV 8 | Emergency Shutdown | Emergency stop; ON turns Y1, Y2, G and W off | Write |
| AV 3 | Occupied CL SP/ Fahrenheit | Occupied cooling setpoint, °F | Write |
| AV 21 | Occupied HT Setpoint | Occupied heating setpoint, °F (DB Mode off) | Write |
| BV 4 | System Reset | Lockout reset; set ON then back OFF | Write |
| BV 10 | SF Status | Supply fan running | Read |
| BV 3 | C1 Status | Compressor 1 running | Read |
| AV 34 | Zone Temp Status | Space temperature | Read |
| BV 1 | Alarm State | Lockout condition (ON = lockout) | Read |
| MV 1 | Fault | Current alarm as text | Read |
Enable & remote start
Stand-alone, the MPC defaults to occupied. BV 12 Occupied Mode (default ON) sets occupied/unoccupied from the BMS; BV 14 Work Schedule can take a BMS schedule instead. BV 8 Emergency Shutdown turns the Y1, Y2, G and W outputs off. BV 53 Compressor Shutdown disables both compressors, and BV 61/BV 54 disable heating or cooling.
Sensors & values from the BMS
For units sharing one wall sensor, set BV 16 M/S Switch ON on each follower and map the leader's Zone Temp Status (AV 34), Actual HT/CL setpoints (AV 2, AV 1) and Occupied Status (BV 11) to the follower's Master ZT (AV 4), Subordinate HT/CL SP (AV 9, AV 10) and Occupied Mode (BV 12).
Network setup
- MAC address comes from two rotary switches (00-99); ClimateMaster suggests 02 for heat pump 1 and HP number + 1 for the rest.
- BACnet MS/TP on RS-485 at 9.6, 19.2, 38.4 or 76.8 kbps is set with DIP switches SW1-SW4; the Communications Selection jumper picks RS-485 or BACnet over ARC156 (156 kbps).
- The device instance is auto-generated with the address as its last two digits; for more than 99 units turn off 'Auto Generate Device ID' in the Equipment Touch tool and enter it there.
- The same port can run N2 or Modbus instead of BACnet; the protocol is chosen with the same switches.
Watch out for
- Heating setpoint objects (AV 21-24) only apply with DB Mode (BV 48) OFF.
- System Reset (BV 4) is not momentary; write ON, then OFF.
- Manual BVs (28-32) only act while Test Mode (BV 34) is on, which times out after 60 minutes.
- RNet Mode (BV 44) must match the wall sensor type and the W3 jumper.

Integration notes
- Points list from the MPC manual's points matrix; the same table also gives Modbus registers and N2 IDs.
- Temperatures follow BV 39 Metric (OFF = °F); some setpoints have separate °F and °C objects.
- Heating setpoints AV 21-24 apply when DB Mode (BV 48) is OFF; with DB Mode ON the heating setpoint is the cooling setpoint minus the deadband (AV 5/40/45/46).
- Several points are obsolete (AV 8, BV 33) or only for older generations (AV 32, BV 9).
- BV 9 and BV 59 have no access marked in the source; they are listed here as read-only.
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 MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer) 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 ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer)
How many BACnet points does the ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer) have?
This list has 123 BACnet objects: 57 analog values, 62 binary values, 4 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer) BACnet points are writable?
68 of the 123 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 ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer) BACnet documentation?
The source is MPC Multi-Protocol DDC Controls - Application, Operation & Maintenance Manual (97B0031N01), revision 2025-12-11, published free by ClimateMaster at https://files.climatemaster.com/97b0031n01-climatemaster-mpc-multiprotocol-ddc-controls-water-source-heat-pump-application-manual.pdf.
What are the minimum BACnet points to integrate the ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer)?
Start with BV 12 Occupied Mode (Occupancy command (ON = occupied)); BV 8 Emergency Shutdown (Emergency stop; ON turns Y1, Y2, G and W off); AV 3 Occupied CL SP/ Fahrenheit (Occupied cooling setpoint, °F); AV 21 Occupied HT Setpoint (Occupied heating setpoint, °F (DB Mode off)); BV 4 System Reset (Lockout reset; set ON then back OFF); BV 10 SF Status (Supply fan running); BV 3 C1 Status (Compressor 1 running); AV 34 Zone Temp Status (Space temperature); BV 1 Alarm State (Lockout condition (ON = lockout)); MV 1 Fault (Current alarm as text).
How do I enable BMS control of the ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer)?
Stand-alone, the MPC defaults to occupied. BV 12 Occupied Mode (default ON) sets occupied/unoccupied from the BMS; BV 14 Work Schedule can take a BMS schedule instead. BV 8 Emergency Shutdown turns the Y1, Y2, G and W outputs off. BV 53 Compressor Shutdown disables both compressors, and BV 61/BV 54 disable heating or cooling.
Can the BMS supply sensor values to the ClimateMaster MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer)?
For units sharing one wall sensor, set BV 16 M/S Switch ON on each follower and map the leader's Zone Temp Status (AV 34), Actual HT/CL setpoints (AV 2, AV 1) and Occupied Status (BV 11) to the follower's Master ZT (AV 4), Subordinate HT/CL SP (AV 9, AV 10) and Occupied Mode (BV 12).
How do I check these points on the real MPC Multi-Protocol DDC Controller - Water-to-Air (Gen 7 and newer)?
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.
