ClimateMaster Commercial DOAS with CM3500 controller BACnet points list
Updated 12 November 2026
The CM3500 controller in ClimateMaster commercial DOAS units has a short fixed BACnet list: Binary Values for the network occupancy command, alarm reset and on/off status of fans, wheel, compressors and condenser fans, and Analog Values for pressures, air temperatures, humidity, output commands and two writable setpoints.
This page lists 38 BACnet objects for the ClimateMaster Commercial DOAS with CM3500 controller — 4 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 Commercial DOAS with CM3500 controller
Write BV 1 Network Occupied Input to switch the unit between occupied and unoccupied, and adjust AV 21 Supply Air Setpoint and AV 22 Zone Air Setpoint if the BMS owns the setpoints. Read BV 2 to confirm occupancy, BV 3 for alarms (0 = alarm), and the supply, zone and outside air values. BV 16 resets alarms remotely.
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.

Enable & remote start
BV 1 Network Occupied Input (read/write) sets occupied or unoccupied mode from the BMS.
Watch out for
- BV 3 is inverted: 0 means an alarm is active.
- BV 16 Remote Reset returns to 0 by itself after a program scan.

Integration notes
- The manual does not say which BACnet card or transport (BACnet IP or BACnet MS/TP) is used.
- Instances are the '#' column of the manual's BACnet points list.
- Analog values are given 'in tenths' (one decimal place) per the manual.
- Eight integer points numbered 1001-1008 (Unit Status, CO2 In Zone, CO2 Outside, CO2 Differential, Heat Wheel Supply Pressure, Heat Wheel Exhaust Pressure, Air Flow Differential Pressure, Alarm Code) are typed 'INT', which is not a BACnet object type, so they are left out. The manual's tables decode Unit Status 0-8 and Alarm Code 1-17.
- BV 3 Alarm Active reads 0 = alarm, 1 = normal (inverted).
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 ClimateMaster Commercial DOAS with CM3500 controller and exports what it actually has to Excel — free.

Questions about the ClimateMaster Commercial DOAS with CM3500 controller
How many BACnet points does the ClimateMaster Commercial DOAS with CM3500 controller have?
This list has 38 BACnet objects: 22 analog values, 16 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which ClimateMaster Commercial DOAS with CM3500 controller BACnet points are writable?
4 of the 38 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 Commercial DOAS with CM3500 controller BACnet documentation?
The source is DOAS CM3500 Controller - Application, Operation & Maintenance (BACNET Points List) (97B0065N01), revision 2016-02-17, published free by ClimateMaster at https://files.climatemaster.com/97b0065n01-climatemaster-commercial-doas-cm3500-controller-installation-manual.pdf.
What are the minimum BACnet points to integrate the ClimateMaster Commercial DOAS with CM3500 controller?
Start with BV 1 Network Occupied Input (Occupancy command (0=Unoccupied, 1=Occupied)); AV 21 Supply Air Setpoint (Supply air temperature setpoint, °F (45.0-99.9)); AV 22 Zone Air Setpoint (Zone temperature setpoint, °F (55.0-95.0)); BV 16 Remote Reset (Write 1 to reset alarms); BV 2 Occupied (Occupied status feedback); BV 5 Supply Fan (Supply fan on/off status); AV 6 Supply Air Temperature (Supply air temperature, °F); AV 7 Zone Air Temperature (Zone temperature, °F); AV 18 Outside Air Temperature (Outdoor air temperature, °F); BV 3 Alarm Active (Unit alarm (0=Alarm, 1=Normal)).
How do I enable BMS control of the ClimateMaster Commercial DOAS with CM3500 controller?
BV 1 Network Occupied Input (read/write) sets occupied or unoccupied mode from the BMS.
How do I check these points on the real ClimateMaster Commercial DOAS with CM3500 controller?
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.
