I loved the idea of this thermostat so much, I bought two. The first hurdle was installation. I chose a professional installation through Nest, but after 3 failed attempts to schedule "local" installers on their list. I gave up. It seems that the contracted installers have a certain mileage limit they commit to as Nest Certified Installers, but won't actually travel more than 20 miles or cross State lines to do a job. At least that's the way it is where I live. Nest would schedule and the contractor would call me directly and tell me they couldn't do the job and I should call Nest to find another installer.
So, I lost two days of work dealing with that hot mess. Nest was kind enough to refund the install fee and my local Heating guy took the amount I was quoted by Nest. So, it was a Win/Win except for having to burn two days of vacation. The install was a breeze for the Heating Company tech. He had one in his home and one in his vacation home. He had nothing but good things to say.
The last six weeks have been great. I've been watching energy savings rack up on the iOS App by setting my heat to a 50 dgree low while away 5 days per week. In fact a friend just asked me today how I liked the T-stat. I raved about it and he plans to buy one tomorrow. Then I got home.
The entire upstairs was cold, it's 18 degrees outside and snowing on a Friday night. My upstairs Nest was showing an error E30. One of the wires was not giving power. If there is one thing I have learned in my 40+ years, it's that the wire itself is hardly ever the problem. The problem is usually at the origin or the termination point. So, I fired up tech support on the Nest site, got a case number and called the tech support line. Two hours later, many wire swaps, power cycles, trips to the fuse box and transfers of support personell. I was left with a choice between shorting the wires so that my Oil Burner runs continuosly costing ooodles of cash or sleeping on the couch and hoping the upstairs pipes don't freeze. The Nest tech thinks it's the Tstat base. It's Friday, my new Nest arrives on Tuesday. Really? This product may not be ready for prime time.
