Hi,
I am a new member and don't know much about PIDs. I am also not into brewing but do need help regarding installing a temperature controller for the purpose of maintaining an accurate temperature of my photographic chemicals while processing films. I hope anyone could help me even though I am not a brewer. I purchased a MYPIN TA8-SNR+K and an OMRON SSR 5-24V input/24-240V load. I tried following the circuit diagram provided for the controller. Wired the power supply ok, wired the thermocouple ok (I have temperature readings) then followed the parameter setting procedure and set my target temp to 37.8 C. Problem is when I tried to wire the SSR. I wired the input terminals of SSR to controller output1 which is labeled as terminals 7&8 taking care of polarity. I then wired a test lamp to the SSR output terminals. When I turn on the power supply, I can see the pilot lamp (not the test lamp I connected) of the SSR light up but the test lamp I connected does not light up. I then tried to connect my heater (a griddle without the thermostat) to the SSR instead of the test lamp but the heater is not being powered up. The test lamp should have lighted or the the heater should have powered up upon turning on the power supply because the default state of the temp control SSR output is ON, right? Am I doing something wrong with my wiring? I just need to set up a temperature controlled water bath (A 4" x 14" x 14" tray) and immerse by bottles of chemicals. It is a simple setup and think a very expensive temp controller would be overkill. The MYPIN controller's price is just about right for me. Thanks for any help you could offer.
