Unfortunately, no, you cant use the factory sensor. Double check that this is the neutral! Terrific write-up thank you for posting it! See here for details. I was like WTF. Once warmed up, the recovery time is quick and the swing is fairly minimal. The PID is really converting the mains voltage to 12VDC both for its internal operation and to drive the SSR, so the PIDs draw is quite small. Im so thankful for this. different wiring though. The KIT-GG PID controller kit replaces the function of the mechanical coffee thermostat. Auto-tuning PID cooling/heating control This will give the REX-C100 enough time to auto-tune its PID settings for the boiler.
