PID wiring

Somebody please help, I have my EHERMS control panel completely wired, except for the RTDs.
I know that on my PID, terminals 8,9,10 are for the RTD. I have 3 wire RTDs with a red, white and black wire. Best I can tell the white is common and goes on terminal 8. That is as far as I can get.
All the articles I can find talk about 3 wire RTDs having 2 reds. I'm lost.
Help!!

Tells us more about your PIDs and RTD's - who made them, what model, etc. Have you called/contacted the seller(s)?

RTDs are PT 100

That's a MYPIN TA4 PID. Here's a great thread -> https://www.homebrewtalk.com/f170/mypin-t4a-probe-issues-414837/ discussing this PID and issues with the probes.

Sorry this isn't a more thorough discussion of what's going on, but I use other PIDS and RTD's. Do a forum search on MYPIN and you'll find a lot of others who do.

Good Luck

Thanks so much for your help. The link you posted got me pointed in the right direction, but still doesnt really solve my problem. It did narrow down my target area though. The PT 100 RTDs that I got (sourced from Brewer's Hardware) have 3 different colored wires. Everything I can find says they should have 2 similar colored wires and one different color wire.
I have contacted the supplier for clarification.

However thanks to all the other very helpful information I found out that the TA4 Mypin PIDs do not have a manual mode, and therefore will not work for my BK....off i go to buy a new one

Check the wires on your RTDs with an ohmmeter. Two of the wires should be a dead short--no (or very low) resistance; those would go to terminals 8 and 9 and the remaining wire would go to terminal 7.

Thanks so much

one addition to that, the one that goes to 7 also needs to be jumpered to 10

Thanks Mike!
HBT rocks...you guys are awesome

Ok, I finally got a reply from my RTD supplier...


"These are 2-wire RTDs The sensor is on the black and white wires, the red is unused. At your PID, you can jump the black wire across both red terminals."

How does this affect how I wire now?

RTD (Black & white) should be wired to 7 & 8. Put a jumper from 8 to 9. Also looks like you need a jumper from 7 to 10...

Thanks poobah....think I got it
