Simple and intuitive 1

I bought this to replace an old thermostat thermostat that was just one wheel to turn and wasnt at all accurate. This old thermostat was dry contact and served for a gas boiler which is 10 years old. It was connected by 3 son but wasnt electrically powered and served just dinterrupteur. I used my existing thermostat old son to feed the nest 12v. The installation was simple and done in 2 hours taking my time. The thermostat has a week to learn my schedule and then he managed alone. Warning even after learning early must continue to monitor the time since it increases the temperature too. The application works perfectly on iPhone. I find the simple thermostat setting (turn to change your choice and press to confirm). Being able to cut its district heating if we forgot allows us to save (it can also cut itself because it detects when you are not there). What also pleased to be able to turn it on for an hour before returning to the house silk temperature and if you have fixed times it will turn on its own. After more than a week a small graphic lets you know how long your boiler operated daily. It's been a month since I lack so I step back and see the savings but saw that cuts alone when I'm not there the savings will be real.
