UPDATE 12/11/2012: The replacement has arrived and also defective! The knob on the front panel does not respond when activated and there is no latching function noticeable when turning. Quality control knows the manufacturer is not well. So again return.
******************************************************************************************************************************************
UPDATE 19/11/2012: In the meantime, the third device has arrived and mounted. At first glance, everything seems to be OK with this. I will then report back here in a few weeks about my experience with the device. Besides defects and returns, there is nothing more to report.

Update 23/11/2012: Now it also has this thermostat again caught after a few days - total crash, nothing works. In the meantime, I received also the manufacturer of the product recall. Particularly ironic: allegedly been affected only the devices from the 34th week of production. My dates from production week 33. So this statement is not so serious to take as well as the Amazon, it does not concern safety issue. I disagree, because if the thermostat crashes then stops working, the frost protection function! Each of the ever rehabilitate another been frozen line (leave) could know what that means ...
So have my proof of purchase to Honeywell e-mailed and asked to exchange. It was called to the exchange of at least 2 weeks me a life. Obviously it is in no hurry there - that's really the summit. I will tell how it will end.

Update 07/10/2014: First again a supplement: the exchange by Honeywell took time really almost 3 weeks. Now, after one and a half years, I had to also replace the thermostat again. Already at the end of the heating season, I noticed that the room temperature was always higher. Battery replacement, new installation of the adapter and teach again brought no improvement - the thermostat no longer close properly. You hear it acoustically that apparently a gear on a shaft just spins and the valve no longer closes entirely.
On the homepage Home Xpert by Honeywell can be found except an expensive hotline number no information to process your repair claims. So I turned me directly at Amazon. Advance replacement by Amazon was exemplary. The very next day the new thermostat was there and working properly. Meanwhile, one way, is arrived at firmware version 2.0.
