Hot Liquor Tank (HLT) temperature control with an STC-1000 Temperature controller from Ebay.
Temp controller in place from the rear:

Case internals so far, thought I’d include an Earthing block (which I didn’t use, though I might earth the Pipework on the HLT sometime):

Temp sensor fitted to side of HLT http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=0461159 :

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 (*a couple of small 2-pin plugs & sockets would do this).
Holes cut and sockets in position:

I decided, seeing as I have plenty of case depth, I’d use the full pattress boxes to secure the socket fronts:

The Wiring:
Live Feeds to in series:
- -Temp Controller
- -Heating Relay
- -Cooling Relay
Switched Relay Feeds to:
- -3 Pin Live! on both sockets
To Neutral Feed in series:
- -Both 3 Pin Socket Neutrals
- -Temp controller

Wall Mounted and Wired into a Fused Spur:

The Inside, knot tied in sensor lead so I don’t go pulling it:

Heating LED on, heating up:

No LED indicator showing, Heating OFF, set to 81c with a 1c drop so it stays 80c or above:

🙂 I just need to finish painting the walls, Paint the floor, and complete my Brewery Stand!!
The Plastic box came from www.rselectricalsupplies.co.uk
