As of 2015, programmable thermostats for HVAC systems can be found at many retailers and home improvement stores, such as Amazon, Home Depot and Lowe’s. A programmable thermostat can help homeowners save energy by making more efficient use of their HVAC systems.
Programmable thermostats are available with several program modes. Some models allow a different program to be set for every day of the week, with up to four settings for each day. Other models use a separate program for weekdays and weekends, with some splitting the weekend into Saturday and Sunday. The least flexible models use the same setting for every day of the week.
Some programmable thermostats are wi-fi enabled to allow remote programming, adjustment and monitoring from a computer, tablet or smartphone. The most sophisticated thermostats are learning models that don’t require manual programming at all. Instead, they build a custom program as they are being used. Some programmable thermostats can send monthly reports on energy usage and alert when the air filter should be changed.
Although programmable thermostats help save on energy, some are not easy to use. Homeowners should make sure the thermostats they select are easy to program and monitor to ensure the best energy savings. In addition, any thermostat should be checked for compatibility with all parts of the HVAC system.
