Hello guys,
so I have 3 wires all 24VAC that I need to setup a system of logic gates for.
Wires A B C only get 24V when the respective system is powered (A = Heat, B = Fan, C = Air conditioning, D = Common (24VAC always on))
I am thinking relays since it is 24VAC.
Here's what I need in text form:
We'll call it wires A B C D
If (A or B is 24V) AND C is 0V then output 24V from D to the new device
That's it. If either the Heat or the FAN is on, then output power but only if AC is not on!
Hope that makes sense.
