Done a couple of trial runs now. I like it
.
Yesterday created a profile that took the temperature to 66c and held it there before going to 75c and holding it. I used 15 litres of water with the Kegland recommended PID settings for that volume. Worked really well, didn't overshoot either temperature and you could hear it clicking the heater on and off as it approached the set temp.
I was just getting bored and about to switch it off when the RAPT probe auto-powered off. Turns out its default timeout is 1 hour (should have read the online manual). Changed it to 14 hours.
Today I did a 66c hold and boil test with 10 litres of water. I guessed the PID settings which turned out to be wrong as it overshot slightly. For the boil I had a stage that took it to 96, followed by a 102 hold stage. I switched off and removed the RAPT probe before the 96c stage and it was just starting to boil at 96c. When the temp got to 101 I turned the power down to 50% and it held a nice boil. I reckon the internal probe could do with calibrating but it works as is so I'm going to leave it.
Minor annoyance is when you start a profile it puts up a message telling you to press up or down to stop the current stage and it stays there making it difficult to see the temperature as it rises. The only way to get it off the screen is by pressing up or down to end the current stage and thankfully it doesn't come back. I'm going to start all future profiles with a dummy first stage that I can immediately click through. I think the wording of the message is a bit misleading as it implies (well states) its going to stop the current stage, it doesn't, it completes the current stage and moves to the next.
I've got some thoughts about having more control over profile settings which I would have thought are already in their development plans.
Anyway, can't wait to use it to make beer.![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
