Temperature Sensors in Wrong Order?

I've assumed that the temperature probes are ordered left to right T1 T2 T3. It seems though that on my unit they are T1 T3 T2. What is the expected order?

I couldn't find answer in RA Reference 2.1.5 or RA Guide 1.1.2

Weirder question: If they are all gang wired on to a single OneWire pin how does the RA know which one is which?

Mike - It goes by the laser etched serial # on the probe. The oldest manufactured probe will be T1 wile the newest will be T3.

Yowza! That's not at all confusing. ;-p OK, I guess I have to label all of my probes.

I wasn't quite that smart. I figured out which order then went in before I put the head unit in the cabinet but I neglected to label them afterwords. I have a real nifty label maker designed specifically for cables too. Just forgot to label em.
