Temperature Controller STC-1000

[Southern Softy]

I have just taken delivery of one of these controllers.

I have been struggling for years moving brew belts up and down my fermenting bin. On a recent brewery tour to the excellent Great Western Brewing Company in Bristol the head brewer convinced me that stable fermentation temperature would make a huge difference, so took the plunge and all I need now is a fridge.

The purpose of my posting is to tell everyone of the excellent service from the guy I bought it off in Hong Kong - he is on ebay called elin.ou. First of all he sent me a 110v one by mistake, I emailed him and within hours he responded saying sorry and that he would send a 220 v replacement. Only a week later, all the way from Hong Kong, it arrived. He didn't want the old one back so now have a a spare probe and a useless 110v controller. Not bad for £17 including postage.

Very good service I have three of them and the only thing I have to stop is the pesky auto alarm

Yes, good service indeed, and they work well. I have 4 of them in service now.
I got all my fridges from freecycle.

I don't have any alarms on them though.

The stc's I have, have an auto alarm which sounds when the pre set cooling and heating are exceeded, and as far as I can see, the alarm feature can't be turned off, twas one of the reasons I was considering not using them in favour of ATC800. I bought them with the intention of disabling the speaker.

I've just had to read the instructions for mine again, it seems the alarm goes off when the sensor is open or short or "when the measuring temperature exceeds the measuring temperature range". Now I've never heard the alarm go off so I'm assuming it means if the temp goes below -50 or above 99?

I'll have to have a play with it and see :hmm:

 

[Runwell-Steve]

Ahh, OK, mine do actually have alarms, I know this as I just disconnected the sensor on one of them while relocating it, the alarm went off.

I've never actually heard one of the alarms go off apart from that though.

Just had a quick play and the alarms didn't make a peep, set at 20 deg c then probes placed in an ice bath, that's even better news for me
As you said Keith it must mean upper and lower maximums (not your pre set value) when it talks about triggering the alarm, and naturally probe failure.
