REX- C100 is a dual line display Proportional Integral Derivative (PID) controller. The top line displays the measured temperature / Process Variable (PV) and the bottom line displays the target temperature / Set Variable (SV). This controller is compatible with with K type thermocouples.
REX-C100 temperature controller initial setup. Title: REX-C400,C410,C700,C900 Instruction Manual Author: RKCE.ORIHARA Keywords: IMNZC18-E3 Created Date: 2/7/2001 4:26:10 PM.
When connected to a solid state relay (SSR) a heating element can be controlled to maintain exact temperatures while mashing.
Please refer to our product pictures that show the wiring diagram to the back of the controller.

Here is a video of what it's doing:
00:00 - 00:26 ; PID is holding a temp above the set-point (But I don't think it's the actual temp of the oven... notice the discrepancy from the red number to the thermometer values)
00:26 - 1:29 ;PID drops below 399 and loses it's mind! ... I think the red number then comes back down to the actual temperature.
-------------------------------------------------------------
To elaborate on the issue... I charted this out with a stopwatch! PID was set and auto-tuned to 400F.
Exact testing set-up (Auto-Tuned to 400 with this set-up twice in a row) (Right cooking probe is what is charted in Orange Below):
It oscillates on about a 12 min cycle:

Notes/Misc:
- Check out the sharp drops and gains on the PID temp.
- I wonder if there is a frequency or dead-band setting that I could change? The oven stays shut off for a long time after it hits the 420 mark.
- I feel like a ~57 degree fluctuation is unacceptable! LOL
- My Rex-C100 is the knock-off version that only utilizes 3 digit codes instead of 4 digit codes for most of the options.
- I can't get the df setting below 001
Thanks for any help!
