Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) BACnet points list
Updated 6 November 2026
ClassMate and SchoolMate classroom units use a Carel pCOOEM+ controller; an optional BMS card gives BACnet MS/TP or BACnet IP/Ethernet (LonWorks and Modbus are other options). The BMS can switch the unit on and off, send an occupied command, reset alarms, send a heartbeat and write cooling, heating offset, unoccupied, standby, humidity and CO2 setpoints. It reads temperatures, humidity, CO2, damper and valve positions, relay outputs, digital inputs and individual alarms.
This page lists 80 BACnet objects for the Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) — 23 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Modine’s own free documentation, linked below.

BMS integration notes: Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+)
Pick BACnet MSTP or BACnet IP/Eth as the BMS card protocol in Service > BMS Configuration and set the instance and address with the Termconf plug-in screens. Use BV 16 Superv_OnOff to run the unit and BV 27 for occupancy, write the cooling setpoint (AV 9) and heat offset (AV 10), and keep BV 17 heartbeat toggling if the heartbeat is enabled. Watch the general alarm (BV 15) and the individual alarm BVs.
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 16 | Superv_OnOff | BMS on/off command | Write |
| BV 27 | bms_occ | BMS occupied command | Write |
| AV 9 | pco_temp_setpt | Cooling setpoint | Write |
| AV 10 | ht_offset | Heating setpoint offset below cooling setpoint | Write |
| BV 17 | heartbeat | BMS heartbeat, when enabled in the BMS menu | Write |
| BV 26 | BMS_Reset | Alarm reset command | Write |
| BV 6 | Supply_fan | Supply fan relay status | Read |
| AV 8 | cntrl_sensor | Control temperature | Read |
| AV 4 | sa_temp | Supply air temperature | Read |
| BV 15 | General_Alarm | General alarm | Read |
Enable & remote start
BV 16 Superv_OnOff is the BMS on/off command and BV 27 bms_occ the BMS occupied command; the unit display shows 'OFF by BMS' when the BMS has switched it off.
Heartbeat & communication loss
The BMS Configuration menu has an 'Enable heartbeat' option (default No), a timeout and an 'If BMS Offline turn unit' On/Off choice; the BMS writes BV 17 heartbeat. When the heartbeat is lost the 'BMS Offline (No Heart Beat)' alarm is raised and, depending on setup, the unit turns off or stays in occupied mode.
Network setup
- BMS card protocol and BMS port 2 protocol are chosen in Service > BMS Configuration.
- Set Termconf PlugIn = Yes to edit the BACnet MS/TP (baud, MAC, Max Masters, Max Info Frames) or BACnet IP (instance, IP, subnet, gateway, DNS) settings.
- Use Function = Write and Update = Yes to send the settings to the card.
Watch out for
- Integer AVs start at 1001; do not confuse AV 1-24 (analog) with AV 1001+ (integer).
- If the heartbeat is enabled and BV 17 stops changing, the unit can shut off.
- Geo water, ERM and electric heat points only carry data when those options are fitted.

Integration notes
- Object names here are the Carel variable names printed in the manual; the BACnet column gives only the object address (AVn / BVn). Check the names your BACnet card reports.
- Carel analog variables are AV 1-24, Carel integer variables are AV 1001-1017 and digital variables are BV 1-39.
- The manual marks several fan, wheel and fan-alarm rows with an asterisk but prints no footnote for it.
- AV 1017 is printed with the variable name CURRENT-YEAR but described as Current Minute; it is shown as printed.
- Heating setpoint is the cooling setpoint minus the heat offset (AV 10); AV 11 shows the result.
- Engineering units are not printed in the table. Source table: manual pages 30-31 (80 objects).
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 ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) and exports what it actually has to Excel — free.

Questions about the Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+)
How many BACnet points does the Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) have?
This list has 80 BACnet objects: 41 analog values, 39 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) BACnet points are writable?
23 of the 80 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 Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) BACnet documentation?
The source is Modine Controls System Manual - ClassMate and SchoolMate Units, Models CMD/CMP/CMS and SMG/SMW (AIR74-525.1), revision 2016-07, published free by Modine at https://modine.worksmartsuite.com/PORTAL/io_modules/IOGETIMAGE.php?type=stream&filename=AIR74-525.pdf.
What are the minimum BACnet points to integrate the Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+)?
Start with BV 16 Superv_OnOff (BMS on/off command); BV 27 bms_occ (BMS occupied command); AV 9 pco_temp_setpt (Cooling setpoint); AV 10 ht_offset (Heating setpoint offset below cooling setpoint); BV 17 heartbeat (BMS heartbeat, when enabled in the BMS menu); BV 26 BMS_Reset (Alarm reset command); BV 6 Supply_fan (Supply fan relay status); AV 8 cntrl_sensor (Control temperature); AV 4 sa_temp (Supply air temperature); BV 15 General_Alarm (General alarm).
How do I enable BMS control of the Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+)?
BV 16 Superv_OnOff is the BMS on/off command and BV 27 bms_occ the BMS occupied command; the unit display shows 'OFF by BMS' when the BMS has switched it off.
Does the Modine ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+) need a BACnet heartbeat or have a communication timeout?
The BMS Configuration menu has an 'Enable heartbeat' option (default No), a timeout and an 'If BMS Offline turn unit' On/Off choice; the BMS writes BV 17 heartbeat. When the heartbeat is lost the 'BMS Offline (No Heart Beat)' alarm is raised and, depending on setup, the unit turns off or stays in occupied mode.
How do I check these points on the real ClassMate / SchoolMate Vertical Unit Ventilators (Modine Controls System, pCOOEM+)?
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.
