BMS integration notes: Contemporary Controls Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX

Integration in brief

For each unit, write On/Off, Mode, Setpoint and Fan Speed; read return air temperature, on/off and the error code.

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.

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 Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX and exports what it actually has to Excel — free.

Questions about the Contemporary Controls Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX

How many BACnet points does the Contemporary Controls Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX have?

This list has 72 BACnet objects: 30 analog inputs, 24 analog outputs, 9 binary inputs, 9 binary outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX BACnet points are writable?

33 of the 72 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. The source has no read/write column, so this is inferred from object type.

Where is the official Contemporary Controls Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX BACnet documentation?

The source is BASgatewayLX Modbus device profile Mitsubishi_AG150_IP50 (Mitsubishi_AG150_IP50_LX.csv), published free by Contemporary Controls at https://www.ccontrols.com/support/dp/MitsubishiProcon.zip.

What are the minimum BACnet points to integrate the Contemporary Controls Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX?

Start with AO 10 Unit A On/Off (Write) (Unit A on/off command); AO 7 Unit A Mode (Write) (Unit A mode command); AO 6 Unit A Setpoint (Write) (Unit A setpoint command); AO 8 Unit A Fan Speed (Write) (Unit A fan speed command); AI 1 Unit A Return Air Temp (Unit A return air temperature); AI 9 Unit A On/Off (Read) (Unit A on/off status); AI 3 Unit A Setpoint (Read) (Unit A setpoint in use); AI 2 Unit A Error Code (Unit A error code).

How do I check these points on the real Mitsubishi Electric AG-150 central controller via Procon Mod-IP/50 via BASgatewayLX?

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.
