Hi,
I have a ventilator that can operate on two speeds. Matter of connecting the live wires to the correct pins. But I want to be able to use either speed without putting power on both connections at the same time, what would blow out the ventilator. So I need a relay. Is it possible to use the Shelly 2.5 for this purpose? If connection one is on, two is always out or both out but never both on? Thanks in advance.
