Very very happy with my thermostat, it does much more than the older model I will recomend it always. Sorry Pete , I think the unit is awesome!

Just some feedback... I was a VERY satisfied user of your older product, which I purchased back around 2001. It was easy to use and always worked. We even referred several friends who ended-up purchasing the unit. They were also happy. Unfortunately, it died a year or so ago. We were so happy with the old product that we did not even consider purchasing from another vendor. However, we have been extremely disappointed with the new CEM-24. The user interface is so difficult to navigate that we have literally lost HUNDREDS of dollars in wasted heating because when we thought we had changed the settings it turns out they were not changed. Most recently, some friends were at our cabin. They thought they had put the unit in Economy Mode. I called the thermostat yesterday, and it turns out the unit was still set for heating. So I changed the set heating temp to 50. The unit read back that the set heating temparature was now 50 degrees. I called tonight and it said the set heating temparature is still 70! Please take me back to the simple days when I called in, pressed 2 for economy mode, and hung up. None of this stupid *0#, *4#, *9# ... RIDICULOUS!! seriously. Three button presses to do a function?! And then you have to save it even though it told you it was already set? What a piece of crap! You can be sure I will not be referring anyone else. In fact one of them asked me about it the other day because their thermostat is beginning to show signs of age. I told them not to bother with the newer product.
