The 2nd Generation T200577 thermostat by Nestis a very good thermostat in its own rights but what sets it apart from the competition is its “Learning” capability. No we are not talking about robotic thermostats that you can train. By learning we mean that this thermostat can understand your heating and cooling requirements and automatically change the temperature at the right time before you even need to intervene.
This is how it works.
Say you set the temperature of your home at 25 degrees every Monday to Friday morning, at 22 degrees on weekend mornings, 24 degrees in the evenings and 20 degrees in the night. After a few days or couple of weeks of setting manually, the thermostat learns your schedule and automatically switches to the desired temperature at the correct day and time.
The device has an “auto-away” temperature setting. If no motion is detected for 2 hours, the thermostat thinks no one is at home and switches to auto-away temperature to save energy. It usually takes 2 hours but if you leave home every day at the same time, the device learns your schedule after a few days and switches to auto-away mode after only half an hour
Another good feature is that the backlight of the Nest changes colors depending on the operating mode of the device. Blue means it’s cooling, red/orange means it’s in heating mode and black means it’s idle.
As you can understand, this is a great thermostat if you want an intelligent piece of device at your home that understands your routine and responds accordingly.
