Maico Ventilation Systems

Use cases

• Monitor supply and exhaust temperatures, airflow, and humidity on a live dashboard for each ventilation unit.
• Create an alert when filter remaining life drops below a threshold so maintenance can be scheduled proactively.
• Adjust ventilation level and operating mode remotely without a site visit.
• Track exhaust air humidity trends over time to verify proper moisture management in residential buildings.
• Trigger boost ventilation remotely during high-occupancy events or after renovation work.
• Compare fan speed and airflow data across multiple Maico units installed at different customer sites.

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the Maico ventilation unit, ensuring both devices can communicate over Modbus TCP.
2. 2Verify that the Modbus TCP interface is enabled on the Maico unit and note its IP address and port number (default Modbus TCP port is 502).
3. 3In the ModbusCloud portal, add a new device and import the Maico Ventilation Systems template from the template library.
4. 4Enter the IP address of the Maico unit and confirm the correct Modbus TCP port in the device configuration.
5. 5Test the connection by reading a few key registers such as supply temperature and current ventilation level to confirm communication.
6. 6If you use external CO2 or room humidity sensors, configure bus registers 764 and 763 to supply those values to the Maico unit.
