* A programmable thermostat is the best choice when looking to save money on heating and cooling.
* The majority of digital thermostats are compatible with gas, heating oil, electric heating and air conditioning systems.
** If both heating and air conditioning units are connected to the thermostat, it is important to make sure that the digital thermostat will function with both systems.
* Due to the limited number of features the lowest price thermostats are often times a great option and easier to use and understand.
*** Most people who purchase complex programmable thermostats never take the few minutes to read through the user's guide to learn about the numerous features.
