Yes, and it represents a significant improvement over the early TH6320ZW2003. Sensors have better stability, the resolution of 0.5 degree works consistently now, and perhaps best of all they have introduced a report threshold for both temp and humidity.
One weird thing though. The new ones come with a much larger (wider) base plate. Fortunately, the new units are a perfect fit for the old base plates, so all you have to do is pull off the old one and pop on the new one.
Be sure to leave the batteries out when you initially pair. There are reports that if the initial pairing is done with batteries in place that the unit will not advertise itself as a routing node.
Not sure I understand the question well enough. Are you asking what the trigger is for a higher stage? Or are you asking is CPH done by stage?
If the former, it isn't configurable. I expect it moves to a higher stage if it isn't able to reach the set point in a rational time. It learns what the system is capable of over time so it should be pretty good at handling this. Same as for recovery.
If the latter, the CPH is per type (heat/cool) and per stage.
The manual is available here. Installer menu begins on page 15. HTH.
For the 500-series version, when the set number of CPH for heating stage 1 or cooling stage 1 doesn't meet the heating or cooling demand, it switches to stage 2 for cooling (or 2 and then 3 for heating).
So to delay the switch from stage 1 to stage 2, one could play with the number of CPH in each stage .....
But that type of staging control is not as efficient in my use as temperature delta based staging.
Shame, because I liked everything else about the T6.
While I no longer have multi-stage to test with, I believe the thermostat is relatively smart in this regard. I don't believe stage transitions are determined determined by CPH but by the performance history (temp/time) of various stages to reach a give set point. I certainly see recovery working this way.
Remember, CPH doesn't dictate a maximum run time--it is a maximum number of starts. I don't remember where I read this, but I really like the phrasing... "Temperature (distance from set point) always trumps CPH."

Thanks for the info; I have one on order so good to know. I read about pairing on wired power(common) first someplace, but didn't know it was specific to the 2007.
About a year with a two-stage heat-pump. In the end I went back to a thermostat that controlled staging using temperature deltas. Kind of a shame, because I really liked most other things with the T6.
That's bad--clearly something wrong, either with the algorithm, the temp sensor or the hysteresis damping. FWIW, I had issues with temp (and humidity) in my old TH6320ZW2003s. One of my units was okay, the other was not so great. Both seemed heavily dampened, and would veery rarely report a 0.5 degree.
At least as far as the sensor / dampening issues are concerned, my new ones are much better. Unfortunately, I don't currently have multi-stage, so I cannot say whether the multi-stage behavior you saw has been corrected or not.
Yeah, it's been rolled into the generic thermostat drivers. The generic thermostat driver reads any available attributes from whichever thermostat. @bcopeland was the dev on it.
