Thermostats are the controls of your heating and cooling system. They measure the temperature in your home versus the desired set point temperature. Most thermostats on the market now are programmable but there are many different brands and varieties available. Some come with touch screens, in WIFI models, and now there’s learning smart thermostats as well. A common programming option is the 5-2 day variety. This is where you have your normal week day temperatures set and different options for the weekend. The 5-1-1 has a different option for Saturday and Sunday. Then there’s the 7 day programmable which gives you each day of the week with a different schedule. The learning thermostats are new to the market and are not as widely supported yet. The WIFI thermostat can be of great use because some models offer control from your smart phone with an app provided by the manufacturer.
