All other control voltage is dead on 26 volts. All new control wire to both. Have since replaced with some Emerson thermostats and have had no further issues. Just curious if others have seen this issue with any of the T series line.
    Same issue voltage drop on O/B terminal set for B on T6 Pro TH6210U2001.
    Grabbed another new out of the box same issue 7 to 11 volts drop meassuring common to reversing valve at OD unit. Jumped R to B (reversing valve) at stat bingo 24 v. Installed TH8321R no voltage drop.
    I called Honeywell tech support gave them serial numbers and date code with issue. I find it hard to believe HTS stating they dont have a recall or any system notes indicating issue with voltage drop on T6. Serials 1936JE392578 1910JE025626.

    Just a heads up on the vision pros. They have redesigned the battery clips for the display battery. We have has a number of warranty returns because clips are breaking when the battery is installed.

    Damm I thought my old stock of T6's were ok but got wrapped around the axle today with a customers failed thermostat that wouldn't energize the RV. So I said let me show you let me validate it with this new thermostat and lo and behold it didn't friggin work! Would not energize no mater what. So I had another one and set up a stat test center here at the house and this one wouldn't DE-energize the RV no matter what. I spent too many hours friggn around with this honeywell crap. Should I go look for a LG unit? Maybe a pioneer enhanced version or a sukme special from China?
    I hear they have new T6's in stock that actually work but I will have to bring my little test setup to make sure. I don't like looking like a fool or like I sell shit hardware in front of a customer.

    The series 6 T6's are on the selves here and are marked as such on the box. You may want to talk to your supplier to see if he'll switch your current inventory out. Honeywell should cover it.

    I still have not had a single failure.
    My slow time lined up just right that I still haven't installed a residio built t6 and now I am seeing the series 6 on the shelves.
