SEVi SEC-20 BASIC Control Unit


Every SEVi HRV-System needs a Control Unit, which controls the entire ventilation system.


The SEVi SEC-20 BASIC Control Unit operates up to 6 SEVi Ventilation Units.

You can adjust the fan speed (4 levels)and the operating mode (heat recovery ventilation or permanent ventilation in the summer).

Compared to the SEC-20 control unit, the SEC-20 BASIC does not include an operating hours meter and the option to connect an external humidity switch.
