BrewPi Help
BrewPi Help
So I've finally ended 15 months of procrastination (believe me, I'm an expert procrastinator) and put my brewpi together. It's currently slowly ramping down a stout to 4 ready for kegging and I wish I'd got my backside into gear earlier as I'm pretty impressed with it.
All my pid values are the defaults and one thing I've noticed is that after a cooling cycle the fridge will slowly warm up until it's warmer than the beer by about 1c and then another cooling cycle will kick in. The profile is performing a slow ramp down of temperatures to bring a stout down to 4c to help clear it ready for kegging. Is this normal? I'd expect a cooling cycle to start just before it reaches the beer temperature.

Re: BrewPi Help
For the beer temperature probe I ended up using red silicon ones fro the netherlands. They're more expensive, but they'll actually fit in the thermowell. The black ones from china aren't always 6mm like they say (I bought 3, one was 6.2, one was 5.9 and one was 7mm). The 5.9 will only fit in as far as the black cover. The other 2 won't fit in at all.

Edit- got one on brewbuilder...
I heat my fv with a heated tray- what would this mean for the position of my second temp probe? Or would i need to change to heating the space in the chamber rather than the fv directly?

Re: BrewPi Help
Just a heads up. You might be lucky using those cheapy 2-channel relay boards but they can cause problems especially on 240v. The 120v in US doesn't seems to be as bad but if you find your Brewpi works fine until you want to control the fridge and heater then look at using 2x SSR which are around £5 each and what the original Brewpi kits used.beerbeerbeer wrote:Thanks guys thats really helpful.

Re: BrewPi Help
heater yes,fridge no as some ssr's cant cope with inductive loads like fridge compresor motorsto control the fridge and heater then look at using 2x SSR

Re: BrewPi Help
These are the ones that were used and are still sold by the Brewpi project so should be fine even on a fridge.beerbeerbeer wrote:Cheers anthony. Do you have a link?

40a should be enough to cope with the inrush current.
