I just built a toolbox RIMS controller with great success, accept for one thing. The PID unit isn't firing the 25A SS relay. I bought an eBay rKc (?) CD-101 unit. Does anyone have any tips for these generic PID? I have the settings set to PT100 RTD temp input. It shows the Out1 light is on, but it doesn't trigger the relay's 3-25VDC input. I know the relay works because a 9v battery kicks it on. Also, the temperature in *C seems accurate, but when I switch to *F, the temperature maxes out around 65*.
Anyone else have gone through these issues?
