I got a bit chilled today under the fan at my desk and probably didn't need so much blowing out (eventually I put on my jacket). How do we work out what settings to have in the room to make people comfortable?

There's all kinds of different modes, timers and fan speeds available. We should do some experiments on hot days and get used to asking around what people think about it -- and recording the favoured settings, as we do for laser cutter settings.

I think we have these things mounted on the ceiling:

The remote controls (which I have labeled) and seem to be kept on the coffee table by the 3D printers and of this kind:

I've turned them both off because it's 8pm and I'm alone, and they are now making a lot of cracking noises, like the sound of ice melting in a machine.

(I also just realized there's no ventilation in the machine tool room, which I can probably cope with by leaving the door open when not making noise. What's going to happen in the other rooms like the quiet room and new Dinky?)

I think we also have the technology to decode and issue the necessary IR codes to control them from the MQTT system using an ESP with an IR controls.

Also, someone should check if @maltman23 has already made an AirconBeGone!

The north AC started snowing when I turned it on today, contractor claimed that would only happen if it was left on overnight but I can confirm it certainly wasn't blowing and I thought it was set to Auto - 19 - (something, I forget what the fan was on).

It seems to be the case that if either is on then both should be on as they share a copper pipe. If one is on then the copper pipe gets very cold for the other one, causing the ice build up. I imagine it would be ok to have one cooling and the other just with the fan on so long as there's some air flow. I don't actually know where the cooling is done, if it's the outside unit then I imagine you'd get cooling so long as either of them was set to cool.

Short answer - both devices should be doing the same thing, both on or both off.
