Airflow Adroit MVHR

Use cases

• Monitor external temperature and MVHR operating state on a live cloud dashboard for each customer site.
• Create an alert when the filter change indicator activates so you can schedule maintenance proactively.
• Switch the Airflow Adroit between boost, away, and at home modes remotely without a site visit.
• Set the boost timer remotely when a customer reports condensation or poor air quality.
• Track limp mode events over time to identify recurring faults before they escalate.
• Activate the fireplace timer remotely to manage ventilation during wood burner use in winter.

Installation

1. 1Connect the Modbus RTU wiring (A, B, and GND) from the Airflow Adroit MVHR terminal block to the RS-485 port on your ModbusCloud gateway (MCG or MLP series).
2. 2Set the Modbus slave address on the Airflow Adroit unit using its onboard controls or configuration menu, and note the address for gateway setup.
3. 3Configure the serial port on the ModbusCloud gateway to 19200 baud, even parity (8E1), matching the Airflow Adroit default settings.
4. 4Import the Airflow Adroit MVHR template from the ModbusCloud template library into your gateway project.
5. 5Assign the correct Modbus slave address in the template to match the address configured on the physical unit.
6. 6Verify communication by checking live register values on the ModbusCloud dashboard, confirming that external temperature and MVHR state are reporting correctly.
