Thanks.
As I said in the Driver thread, (probably should have said it here), I don't think they would work out for my heating system.
I have a hot water baseboard system with a 120 gal storage (buffer) tank. I think the T6, with its cycles per hour logic, is more geared towards starting up of equipment rather than cycling little circulator pumps.
My older Ecobee wifi thermostats seem to be able to control temp down to +/- .5F, so I don't think I'm going to change. At this point anyway.
