I posted the below questions in the brewing & equipment section, but no one chimed in. I know a lot of you guys are incredably knowledgeable and have experience using this same type of system. Can someone out there reply?..... (I did shower this morning, so I don't smell or anything). You don't have to answer every single question I asked, but I really would like to know what's up with some of these unknowns ............
Hello eveyone, I really need sound advice for purchasing the correct Auber Pid temp controller for use with my system. I am in the middle of my build and I am making a single tier Brutus type direct fired gas system. I am using Lp gas from a 20 lb tank through the back gas beam of the stand. I have Honeywell VR8200 standing pilot valves with thermocouples and pilot lights to control the gas flow on the HLT and MLT's 10 inch Banjo burners. I am also using needle valves to control the flame size to each burner.
My first question: There are two Auber Pid/Temp controllers that are similar and I want to know which one is better. The first one is model SYL2362 and the other is the SYL2342.
I want to use RTD probes attached to tees coming out of the HLT and MLT vessel's liquid lines, to monitor the temperature, and have the correct Auber controller turn the Honeywell valves on and off. Both of these models seem like they would work fine, but is one better than the other for how I am going to use them with gas and not electricity?
Question 2: Can any one comment on the performance of their Auber controller and if they are satisfied with how its working controlling the Honeywell valves? Are you using On/Off mode or PID mode?
For instance I think On/Off mode is probably the way I will end up wiring the Auber controller, but is anyone actually using the pid modes for their gas system and solenoid valves? If so does the PID mode work better than ON/Off mode? The SYL2342 has fuzzy logic and the SYL2362 does not.
I would like to know for a five or ten gallon batch and lets say a desired mash temp of 152 degrees, what is the average amount of times the Honeywell valves turn on and off to keep the desired temp range close to 152 degrees in an hour? Does the valve turn on and off twice in 3 minutes, once every 5 minutes, or whatever, in On/Off mode. What is the average in PID mode (if any one has used this mode)? Also how is it working and what is the average times for a set temp on the HLT?
I realize there is a hysterisis band and a range of temps you can set, (two degrees, three degrees, one degree, etc) to activate and trigger the valves, and the SYL2342 has a tighter temp range that it can keep the temp at, but I just want someone to advise about how it is working for them in real life.
I was told (don't know if it is factual) that the Honeywell valves have a life of about 100,000 times of opening and closing before they start to have problems and need to be replaced. Can these valves handle opening and closing repeatedly in PID mode, or is it better to use the On/Off mode?
So there it is....Sorry so long winded but I would really like to learn some answers to the above questions, so I can make the right purchase and use the technology to the fullest extent of how it was designed. I want to have a solid working system with the best performance for the equipment I am using, and have a SMOOTH brew day!
Thanks for your time,
