Hi All, I have been AG brewing with my 3 vessel system for about a year now with few problems until today. Last night I decided to check the calibration on my 3 temperature probes installed on each vessel. I removed them and placed them in a glass of iced water with a standard glass thermometer which showed 0 deg c. I then proceeded to adjust the 3 PID's so all where all reading 0 degrees. I added hot water and again they all showed the same temp, job done or so I thought. This morning at 0630 I powered up the HLT and set the temp at 75 deg, all went well until the pid turned off the element at 75 deg the temperature reading then shot up to 120 deg and fluctuated between 125 and 115. I checked the HLT temp with the glass thermometer and it was spot on 75 deg. When the HLT dropped and the element should have cut in but didn't as the temp was displaying at over 100 deg. I found that if I cut the 12 v power to the pid and turned it on again the temp would display correctly and turn the element on. As soon as the temp of 75 deg was reached the same happened again.
I controlled the brew manually and hit my pre boil gravity. I turned on the kettle and temp on the kettle pid showed 68 deg. It rose to 70 and stayed there even though the element was still on. Started to boil and noticed that PID stated that the kettle temp was minus 23 deg!!
If the fault was with one PID I would probably blame the PID but as two have gone berserk I must have done something as its too much of a coincidence. HELP!!

Re: Sestos D1S Problems
1st to try check all the connections and the cables for internal breaks you may have upset something when you moved them.
I have found plug/socket connectors to be unreliable when disconnected then reconnected currently I'm using old fashioned chock block screw connectors.
It seems unlikely that two PIDs would give up as the same time.
If you have spare PT100s use them to check out the boxs and connectors even to the extent of setting up and running a water only brew.
If your using Thermocouples rather than PT100 it's a new ball game, if you changed any wiring did you use the correct type of cable?
Good Luck. aamcle
