Demystifying Mysterious Things

Smart Thermostats

Smart Thermostats are typically self-learning and Wi-Fi-enabled to optimizes heating and cooling of homes and businesses to conserve energy. They use machine learning algorithms based on reference data gathered during the first few weeks. They are then able to learn people's schedules, which temperatures they like, and can adjust the temperatures based on whether or not people are in the room.

Energy Saving

According to the Nest website, since 2011, the Nest Thermostat has saved over 8 billion kWh of energy in millions of homes worldwide. And independent studies showed that it saved people an average of 10-12% on heating bills and 15% on cooling bills. So in under two years, it can pay for itself.


The Nest Thermostat learns about your home. Ten temperature sensors track the temperature in your home and how quickly it changes. It’s not too bright at night or too dim during the day. Ambient light sensors adjust how the screen lights up. It looks to see if anyone’s home. The activity sensors have a 150° wide-angle view. Is your home too muggy? A humidity sensor shows you indoor humidity so Nest can manage your whole-home humidifier or dehumidifier.


The Nest Learning Thermostat works with 95% of 24V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar and geothermal. Heating: 1,2, and 3 stages (W1, W2, W3). Cooling: 1 and 2 stages (Y1, Y2). Heat pump: with auxiliary and emergency heat (O/B, AUX, E). Humidifier or dehumidifier (HUM, DEHUM). Fan (G). Power (C, RH, RC)
