Bigster my Maplins thermo was knackered
I wired like yours and same result...a permanent feed to the fan with and without the relay LED being on...not good.
I might get another one and try again but going to look into alternatives first, cheap ones of course

IRM, my ice bottles are now lasting at least 48 hrs
The current set are 48 hours and still 1/2 frozen.
With the drop in air temp recently (23 deg c in house) the fan is only coming on every couple of hours and maintaining 20 perfectly

Shame about your joe maplins thermo. Hope you have better luck with your next try.

Have been in the garage tonight filtering and bottling a load of wine and kept hearing the fan on my chiller kicking in every 3 or 4 mins but is only running for 10 seconds . Its maintaining a very nice temp range of 17.2 to 17.7c though

That's a superbly tight temperature range Bigster, you've certainly cracked that one

I am amazed at how well they work and how efficient they are ice and electricity wise!
I'm very tempted to build one, although i'm still looking out for a suitable old fridge!
