Question
[email protected] 0
I need to control an air conditioning system which presents 2 zero (well very low) voltage connectors from a logic board that I short to tell it to switch on. I can't control the main power supply because of the high load and the need for the compressor heaters to be on (in the winter) at least 5 hours before use.
The single Fibaro switches have two Live feeds. In this case is one of the feeds only connected to the switching function (Presumably a micro relay) so that this live and terminal Q could be used to short (start) the Air con?
Are they electrically isolated from the mains supply on the other live terminal?
