Modine Direct-Fired Make-Up Air MCV/MVV, DCV/DVV (Distech ECB/ECL-403) BACnet points list
Updated 6 November 2026
These Modine direct-fired make-up air units use a Distech ECB-403 programmable controller that joins a BACnet MS/TP trunk. The BMS can turn the unit fan on, off or auto, write occupied and unoccupied heat and cool setpoints, set the building pressure setpoint and economizer commands, and override space temperature, building pressure and occupancy with network values. Alarms (dirty filter, low temperature, sensor faults, burner lockout, motor not responding) are multistate values.
This page lists 39 BACnet objects for the Modine Direct-Fired Make-Up Air MCV/MVV, DCV/DVV (Distech ECB/ECL-403) — 26 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 Direct-Fired Make-Up Air MCV/MVV, DCV/DVV (Distech ECB/ECL-403)
Set the MAC address on the controller DIP switches; the device instance follows as 364000 + MAC and the baud rate is auto-detected. Start and stop the unit with network_FanCommand (AV 103), write the occupied heat setpoint (AV 102) and, if fitted, the building pressure setpoint. Monitor discharge and space temperature, the heat command and the alarm multistates.
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 |
|---|---|---|---|
| AV 103 | network_FanCommand | Unit fan command: 0 = off, 1 = on, 2 = auto | Write |
| AV 134 | network_Occupancy | Occupancy override, 0 = occ, 1 = unocc; null = schedule | Write |
| AV 102 | network_OccHeatSetPoint | Occupied heating setpoint, 55-90 °F | Write |
| AV 107 | network_BuildingPressSetPoint | Building pressure setpoint, -0.1 to 0.1 in. w.c. | Write |
| AV 54 | DischargeTemperature | Discharge air temperature | Read |
| AV 51 | SpaceTemperature | Space temperature | Read |
| AV 57 | HeatCommand | Burner heat output, % | Read |
| MV 37 | BurnerLockoutAlarm | Burner lockout alarm | Read |
| MV 39 | MotorNotRespondingAlarm | Supply fan motor not responding | Read |
| MV 32 | Low_TempAlarm | Low discharge temperature alarm | Read |
Enable & remote start
The unit runs when enabled by the BMS through network_FanCommand (AV 103), by a contact closure on digital input DI-5, or by its internal schedule. network_Occupancy (AV 134) overrides schedule occupancy; write null to give control back.
Sensors & values from the BMS
network_SpaceTemperature (AV 132) and network_BuildingPressure (AV 133) replace the local sensor readings while written; write null to return to the local sensors.
Network setup
- MAC address is set in binary on the 8 controller DIP switches (switch 1 = LSB); each unit ships with a unique MAC.
- Device instance = 364 x 1000 + MAC; change the MAC to clear a duplicate instance.
- Baud rate is auto-detected after a power cycle.
- The manual recommends starting MAC addresses at 3.
Watch out for
- The override points stay in force until the BMS writes null; a left-over value freezes the reading.
- network_ManualEconPercent does nothing on units with the building pressure option.
- Cooling points only apply to units built with cooling.
- A low temperature shutdown is reset by setting the fan command to off and then back on.

Integration notes
- The manual calls Table 11.1 'typical' system variables; units with LonTalk (model digit 14 = L) need factory guidance.
- Cooling-related points (cool setpoints, HeatCoolMode, CoolLockout) only apply to units with the cooling option; HeatVentMode applies to units without it.
- network_SpaceTemperature, network_BuildingPressure and network_Occupancy override local values; write null (relinquish) to return to automatic control.
- network_ManualEconPercent is not available with the building pressure option.
- The enumeration texts for the Filters and SensorReliability state sets are not printed in the BACnet table; the display menu shows the sensor alarms as no-fault / open / short.
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 Direct-Fired Make-Up Air MCV/MVV, DCV/DVV (Distech ECB/ECL-403) and exports what it actually has to Excel — free.
