I think we can turn the page on the TM200's and TM220. Using OmniScope, I installed firmware into one TM200, installed firmware into the TM220 as well as adjusting heat & cool setpoints and scheduled times on both. I now have a spare TM200 that can be used in the number 1 position (Zones 1-2-3) or reprogrammed for the number 2 position (Zone 4).
The basic problem was the new firmware installed in the replacement TM200 & TM220. Henry at Newell identified that as the the possible problem & it turns out he was right. I have no idea how long it would have taken to resolve the problem without having OmniScope. It certainly would have interrupted our travel schedule.
I have to thank the folks at Newell as well as at Trillium Electronics for the time and energy spent resolving the problem.
