Easier than I expected to pair with phone. So seems to work fine so far. It changes to a different color disposable on its own at 2 AM, perhaps doing daily update? Find no info regarding such but it always reverts back later on.
Great Thermostat! Highly Recommended.... This was recommended by my HVAC technician over all the others out there and I am delighted with the product. Simple to install, easy to register and now able to monitor and change temps and schedules with my iPhone, even away from home!
Easy to program and change. Even from far away. House was too warm at night, but geothermal heating system shouldn’t be raised more than 2 degrees at a go ($$$). With this thermostat we can now raise the heat 2 degrees at 4 am and another 2 degrees at 5 am and another 2 degrees at 6 am. Better for sleeping and better for pocketbook.
