OK. Next in the ongoing saga of plumbing in our MVHR system.
I have the following issue.
We are installing an MVHR system, which has a low/med/high fan speed run by a remote, wired in switch. All fine, and I asked before how to wire it in, and am doing so with a .75mm yy cable.
BUT... I'd like to run the unit to high if a shower produces an amount of humidity. I can put in a sensor which runs out a line and neutral, but I actually want the switch, three showers and two heat sensors to ALL optionally run the fan on high.
When I turn on the high speed I don't need to turn off the lower speed.
I've worked out that I need a relay, with up to six inputs and one output. But I can't find one online, or, rather, it's likely I'm not looking in the right place.
Help? Please?
