Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3) BACnet points list

Updated 6 November 2026

Short answer

The Modine Control System is a Carel pCO3 controller in MPR packaged ventilation units, optionally with an ERM energy recovery module. A plug-in card gives BACnet IP/Ethernet or BACnet MS/TP (LonWorks and Modbus are other options). The BMS can switch the unit on and off, send an occupied command, reset alarms and write supply-air, neutral-air, dewpoint, humidity and CO2 setpoints. Readings cover temperatures, humidity, CO2, refrigerant circuit values, demands, damper and fan modulation, switch inputs, relay outputs and alarms.

This page lists 138 BACnet objects for the Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3) — 24 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 Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3)

Integration in brief

Select BACnet IP/Ethernet or BACnet MS/TP in the BMS Configuration service menu and set the device instance and address there. Set Enable Unit On/Off to 'By Supervisor' so BV 41 Superv_OnOff starts and stops the unit, then use BV 38 for occupancy and write the supply-air setpoints. Monitor unit status (AV 1023), supply and space temperatures, the general alarm (BV 36) and the alarm codes.

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

In Service > Service Settings > Control Settings, enable only one Unit On/Off source. 'By Supervisor' lets a BACnet or Lon network variable (BV 41 Superv_OnOff, on = active) cycle the unit; the other sources are digital input ID14, the pAD wall stat (pLAN) and the clock schedule.

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 Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3) and exports what it actually has to Excel — free.

Questions about the Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3)

How many BACnet points does the Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3) have?

This list has 138 BACnet objects: 69 analog values, 69 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3) BACnet points are writable?

24 of the 138 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 Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3) BACnet documentation?

The source is Modine Control System Manual - Commercial Packaged Ventilation System, Models MPR and ERM (MCP15-525.0), revision 2012-09, published free by Modine at https://modine.worksmartsuite.com/PORTAL/io_modules/IOGETIMAGE.php?type=stream&filename=MCP15-525.pdf.

What are the minimum BACnet points to integrate the Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3)?

Start with BV 41 Superv_OnOff (BMS on/off command (needs On/Off 'By Supervisor')); BV 38 Occupied_Bms (BMS occupied command); AV 15 space_cl_sa_sp_oc (Occupied supply air cooling setpoint); AV 16 space_ht_sa_sp_oc (Occupied supply air heating setpoint); BV 39 BMS_Reset (Alarm reset command); AV 1023 UnitStatus (Unit status code (1 = on, 2 = off by alarm, ...)); BV 3 Supply_fan_sw (Supply fan airflow proving switch); AV 10 supply_temp (Supply air temperature); BV 36 General_Alarm (General alarm); AV 1030 Alarm_Code (Active alarm code (1 of 3)).

How do I enable BMS control of the Modine Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3)?

In Service > Service Settings > Control Settings, enable only one Unit On/Off source. 'By Supervisor' lets a BACnet or Lon network variable (BV 41 Superv_OnOff, on = active) cycle the unit; the other sources are digital input ID14, the pAD wall stat (pLAN) and the clock schedule.

How do I check these points on the real Atherion Packaged Ventilation MPR / ERM (Modine Control System, pCO3)?

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.
