Can several HRV units be managed with one control?

HRV Helty models equipped with Modbus protocol allow simultaneous remote management of several units via home automation systems. It is otherwise possible to manage the machines via a special App, with a home Wi-Fi network.

Except for the FlowEASY version, all Helty HRVs have Modbus RTU protocol as standard, which allows data exchange and management of several units simultaneously via home automation systems.

Alternatively, machines can be managed via the Air Guard App, which allows multiple HRV units to be controlled via a home Wi-Fi network.
