For anyone interested I am planning to show how to swap pump relay for a small SSR. Am going to use SY4080 from Jaycar but any can be used. As the relay is 12volt coil you will need an SSR that takes 12volt input to switch. The one I have chosen is a wide input range. Note also that there...

Hi marksy Big pliers. Cut the wires long and then strip ends long then twist all together using pliers then cut to length. Sometimes after cutting may need a little twist to get all tight. Then jam them in and crimp. Sent from my iPad using Tapatalk HD

Hi Tommy 160 Nice use of the element! What is the energy density like as far as burning the mash where the plate is? How well does the aluminium base spread the heat? Do you use any kind of thermal compound either paste or sheet between the element and the pot? James zwitter I love the...

Looks great Where did the top screen come from.? Jámes Sent from my iPad using Tapatalk HD

Hi bigmacthepunker SSRs need a load. They are not switches. This is normal. Some have snubber circuits built in and others components to bias the triac or SCRs that do the switching. Thes switch 40 amps a couple of mA leakage is fine. You should never touch the outputs when the controller...

Hi marc280 There is a snubber circuit across the relay and that will allow a small leakage but should not cause an issue. It would have been preferable to put snubber on the pump and tune for the load of the specific pump. We chose the values based on standard pumps like chugger, march 809...

I bought a stack of orings and may never run out' Once I had to make do with a dodgy oring, never again. The silicone is softer and seals well except some of the older mytton rod lids need a thicker ring. Zwitter Sent from my iPad using Tapatalk HD

Breakbeer When powering the mega on USB there is no 12v so the relay will not click, lcd may not work etc the shield board uses the 12v to power the interfaces to the SSRs, relay etc. The old arduinos had a DC socket on them but still depened on how the shield was designed as to whether the...

Hi marc280 I have one thing to check. You are switching active? I once had a circuit using IEC sockets where male and female effective ly have active and neutral on opposite sides for a plug and a socket and a late night of wiring and had one socket, for the pump backwards and pump would not...

Breakbeer A word of warning. If it does not work with "old" software new software is just asking for trouble. You will not be able to see if it has loaded properly, will be unable to do setup etc Get it working before you even attempt the upgrade. The software as shipped is perfectly...

I have the 7 gal Chonical. Never used the ball valves. I ordered fittings from ebay out of china and they are ok. Bought butterfly valves from USA about 50$ a piece. Rebuildable! Got a glass flow tube and a glass end stop. All sanitary fittings. I do prefer the sanitary fittings. I got the...

Hey guys While you are all knee deep in t he code, I have a request. We have some LCD scrambling issues due to the use of a relay to switch the pump. If the wiring is neat it really is not an issue but for some it can be a big problem. So the request is can the LCD be refreshed / re-drawn...

A few comments Immersion heaters are exactly what the second element circuit is designed for. I have had some issues getting 40 litres to boil vigorously and have. A 2400w immersion heater and it gets it going. Be aware that immersion elements are high density heat elements and you may...

Bigmac Does your relay "click"? ie in manual mode when you turn pump on and off does the relay click on and off? I assume the green LED turns on and off? I looked at your photo but a bit hard to see much with the lighting in the base a bit poor. james zwitter

Real beer & others There is no need to apologise! If you kill yourselves with this controller I will be upset!!! If you slag me out or the like, that is up to you and while not encouraged or desired it is a free world. I am far from perfect and in no way normal. But it does not hurt me even...

Hi Big Mac.... Yes can use the second SSR for the pump. If the relay switches it is as easy as switching 12v with the relay and the output to the SSR. A little messy but does not require soldering etc. if you have a soldering iron you can remove the Relay from the board and use the coil end...

Hey Real Beer Been there done that Actually the outer sheath can be any colour you like. I have purple for elements orange for power and black for the pump but have to go find some heavier duty cable for the new controller and bigger rig. James Sent from my iPad using Tapatalk HD

Hi Matt I have a march 809 and a chugger and we also tested with another similar pump and there was little difference between them. I would suggest pushing the 240 v wiring down in the case and try not to have them crossing the low voltage lines. I grouped the low voltage lines together and...

Hi BobCharlie The scrambling is caused by the switching of the pump. Next to the relay is a yellow block and a resistor. These are a snubbing circuit across the switch of the relay to try to absorb (quench) the spark caused by switching of the pump. SSRs are often zero crossing switches so...

Liquid currency No, no need for fuses. If it goes bang you did something wrong. The house fuses should save you. I strongly recommend you have safety switch(s) installed on everything. Has saved me and some friends due to bad wiring in the house. No earth bonds, no earth in lights or half...
