Hello and Merry Christmas!
I am hoping that someone with some more knowledge than myself can point me in the right direction (if what i am trying to do is possible)...
Scenario:
I have an inline extract fan which has 3 modes: Off, On and Boost.
Off is obviously no power to the fan
On is 230v AC to L1 (Live)
Boost is 230v AC to L2 (Live)
Only L1 or L2 can be connected at any one time (confirmed with manufacturer)
My original idea was to have a dual relay control the 230v AC to either L1 or L2. This would still work but i want a fail safe of some sort so that it is not possible for have L1 AND L2 connected at the same time.
So what i would like is a way to "switch" between L1 and L2. If L2 has power, L1 instantly disconnects and visa-versa (or L1 can never have power if L2 does)
What I have is a Quibino Flush Relay x 2 and a Vent Axia HR100W.
Any ideas? For now i just have 1 of the relays hooked up to L2 which is fine but interested to know if someone can think of a viable solution for switching loads via a dual relay.
