I originally purchased the 1st generation of this thermostat. The only thing I didn’t like about the 1st gen thermostat was how far it protruded from the wall. On my final day for the return policy of the 1st gen, the 2nd gen was advertised to be released soon. So, I didn’t hesitate to uninstall the old thermostat to send it back, pre-order and wait on the 2nd gen. The 2nd gen thermostat’s profile in my opinion is perfect for the look and style I desire in my home; It makes my home appear a little more modern, but not too much. The install was easy and it looks great just as with the 1st gen. I noticed a $35 drop in my $120 per month power bill w/the first gen. I have a 2200 sq/ft home w/3bdrm and 2bth that’s occupied by only myself and my wife. My AC system is a basic singles stage AC and a two stage heater; I hooked up six wires: O,R,B(C),W2,G & Y. I live in FL and the AC runs at 82 during the day and 78 at night. I’m hoping for about the same performance if not better with this thermostat. I’ll admit I did try to go with a programmable Honeywell thermostat which ended up not being compatible with my system while waiting on this order. So my options were keep to my pre-order with the 2nd gen nest or keep the old thermostat from over ten years ago with no features. I’m glad to have decided to go with the 2nd gen Nest.
There are Nest only exclusive cost-saving features on this device. So please no ranting on how this is just another overpriced thermostat for those who are reading reviews and are against this product. Move on to another product where people care instead of being a Debbie downer. My two favorite features of this unit are the auto-away and air-wave technologies (for the A/C) which are probably the two most cost saving features for me. Air-wave shuts down the compressor before the push box. Since the coils are still cold from the compressor running, the thermostat knows how long it takes for your home to get from one temp to another. Depending on this time, the thermostat knows when to shut down the compressor to save power while still getting the home to the desired temp. Auto-away is a feature that shuts off the AC within a programmable range if it detects no one is home. My unit is in a hallway that doesn’t see much traffic (I spend most my time in a back office) and this unit still managed to not go into auto-away mode while I’m home. A side note on auto-away though is that it must be trained within the first two weeks before it has an idea of your home activity. Once the unit trains itself, the power saving features will all be automated unless you manually disable them.
