Ok, here we are entering the electronic area (more than simply electrics), but this simple project might have huge potentials for anyone....
The basic problem is this:
I have a brand new enclosed shower cubicle - it has all the basic functions and more, including a fan....the latter is operated via a switch sited conveniently inside the shower (obviously 12v). Now, I expect this fan to give a poor performance - (just by looking at it)....I'm thinking of replacing it with a better one.
There are some promising SELV fans on the market....still, I'm tempted to go for the more powerful in line type - simply because it would allow me to connect an extra extracting vent in the bathroom (no just in the shower cubicle)...still, the main reason for requiring a more powerful fan is that there's going to be a few bends and probably 4m ducting (flat channels).
It would be ideal if the 12v trigger inside the shower could switch the 240v fan on and off - or maybe in conjunction with a timer or humidistat -there are relays that apparently do just that sort of job - basically, I'd like to get one of these "boxes"...connect the red and black 12v wires on one side and the 240v source and load on the other....where can I find such "boxes"? Any advice how to use them?
