The Nest ushers in a new era of aesthetically appealing energy efficiency equipment. With its sleek design and touch screen interface the $250 Nest learning thermostat is looking to revolutionize home heating and cooling and lower energy bills and is optimized for ease of use. Operation is done via the knob with the unit's front surface acting as a button. To raise the temperature turn the outer ring to the right to lower it turn to the left.
Schedule Learning was designed for people who don't want to program their thermostat which is about 90 percent of U.S. users. Schedule Learning is not for everyone. People who may not have regular schedules or those who like to program their thermostats. If a user doesn't like this feature, they can simply pause it and program his preferred schedule more easily than any other thermostat on the market. For the first week schedule learning builds a schedule. Users change the temperature normally. The nest notes their preferred at home temperature and also determines appropriate away temperatures. To account for conditions outside the Nest checks the weather.
The nest thermostat has the ability to since temperature, humidity, light and contains two proximity sensors. Near field activity and far field activity. The near sensor detects motion near the nest display. The far field activity sensor can detect motion up to 20 feet away. The sensors have a 150 degree range. The sensors will detect whether anybody is actually in a room. The sensor will automatically brighten the LCD screen when the user approaches. If the sensors do not detect motion for two hours the unit will activate the away setting.
The nest has security built in and you can pair multiple Nest for managing the temperature in multiple locations. Up to ten nest can work together to save energy and can be controlled from one nest account. Manage your Home or second home from the web or by the Nest Mobile app. The nest mobile app is available for the iPad, iPhone and android applications and can be used through cloud computing.
In the box there is a optional mounting kit. Most existing units will have mounting hole that are wider than the provided mounting plate holes. There may be holes or patches left behind after you replace your old thermostat. You can fix and paint or cover them with the included mounting plate. Using the mounting plate will take away from the sleek look of the nest. If you're uncomfortable messing with wires and holes nest will sell you installation service for $119 plus an additional $25 for any extra units that you want installed. Check our how to change a thermostat thread before replacing your thermostat.
The nest is provided with a requisite wifi antenna, and a second antenna for ZigBee, which leaves open future expansion to communicate with other devices. The nest has a built in rechargeable lithium ion battery. The unit displays its data via a 320 x 320-pixel 1.75 inch display with 24 bit color and is powered by an ARM processor with 512MB of RAM.

The Nest thermostat has the ability to automatically switch from cooling to heating. This is typically called auto changeover. In order for the Nest thermostat to be be set up for auto changer the Nest must be placed into a range schedule. A range schedule is needed when cooling and heating is used during the same day. This may be a day when heating is needed in the morning and cooling is used in the afternoon. Range schedules can't be learned only programed. When using a range schedule you’ll need to pause learning. The Nest Leaf won’t appear when you're using a range schedule but auto away, manual away and time to temperature will still be available.
The Nest thermostat has a built in humidity sensor. The Nest does not have a adjustable humidity set point. The humidity sensor is used to help the system to compensate for the relative humidity in the room.
The Nest thermostat has a new update 2.0. The 2.0 update will automatically update all original Nest thermostat that are connected to Wi-Fi.
Below are the new Nest features in 2.0:
Airwave: On a typical air conditioning system when the compressor shuts off the air handing unit and ductwork stay cool for a while. When your system is running and the humidity is low the new airwave feature in 2.0 will shut off the compressor a few minutes before reaching the target temperature and keep the indoor fan running to spread the cold air around your home.
Enhanced Energy History: No longer locked inside your Nest, this deeper energy data is now available on the Web app, iPad and both Android and iPhone smartphones.
What’s new on Nest:
Range Schedule was added to the Heating/Cooling/Off menu.
Away temperatures was given its own spot in settings.
Updates to the Nest web and mobile apps:
- Get all your info at a glance. See a quick view of the current temperature, Target Temperature and humidity level, and set the fan to Auto or Always On.
- Change your Away temperature.
- Activate a Range Schedule.
- Pause Auto-Schedule or Auto-Away.

The problem with this is that it will evaporate any condensate in the drain pan and put humidity back into the home which you do not want to do in the cooling season.

How does Nest thermostat use the humidity sensor to compensate for humidity? Does it auto adjust the setpoint based on humidity levels? Or is the humidity sensor just used for the airwave feature?
