Mini Digital Temperature Controller

[dcq1974]

Cheers for all the advice on the wiring etc of these mini temperature controllers. I copied Scooby's design and purchased a project box etc from Maplins. Below is a link to the parts if anyone is interested





Here is a link for the box I used http://www.maplin.co.uk/Module.aspx?ModuleNo=1676
Actual box was part number LH23A (MB4)

Cable gland (for mains cable was) http://www.maplin.co.uk/Module.aspx?ModuleNo=24611
Part was UP89W

Grommet I used for the thermometer cable was http://www.maplin.co.uk/Module.aspx?ModuleNo=1780
Part was LR47B.

Works a treat and I now have a nice conditioning fridge up and running

I've only just started fitting my Temp controller into a plastic case...

Temp controller in place from the rear:

Case internals so far, thought I'd include an Earthing block:

Temp sensor fitted to side of HLT:

Controller fitted to case front with approx positions of the Heating & Cooling Sockets:

This box will be on the wall next to the HLT and wired from a fused Spur, When I get a fermentation fridge I'll just get an extension lead and plug it in, though I may have to figure out a switchable Temp sensor to I can swap between two... though I suppose I could just buy a second Temp controller

you may be better off with two for independance I would say.

theses little controllers are the dogs.
happily powering my kegerator for a few months now, and I have to say, in this warm weather, its great to come home to a cool beer!

well i just bought one of the hong kong ebay ones... in approx 10 days time, expect lots of questions about wiring and setup instructions that have been covered already!

chard, its not as bad as it looks, copy the pics.

be aware, when you first power it up, it'll look like it doesnt work.
dumbass here forgot about the intentional delay of 3 mins, cursed, un-wired, re-wired, scratched head, supped beer, then realised!

Yeh im sure ill manage. Need to get the fridge somewhere suitable first. its going to be used as a fermenting fridge and keg cooling fridge as i go. It fits 1 KKTT in or 2 cornies. i know i should get another corny but i havent had great results with it so far. i personally think there is a noticeable difference between a properly conditioned (yeast included) ale and an ale left to settle and put into a corny.

true, but that's a whole other topic!

Is that the sensor that comes with the controller?

[WishboneBrewery]

No mate, its a stainless steel one from RS.

Was it expensive?

[bramswell]

whats the OD of the sensor and what did you use to fit it to the HLT

[Jolum]

No mate, its a stainless steel one from RS.

Sod the probe, where did you source the compression fitting?

I personally like the look of one of these but £100 is a bit excessive

Don't buy it Jolum!

It won't work with these controllers, they need NTC, not PT100 probes.

This one comes with a threaded shaft and fixings, no need for a separate gland:
