An HVAC system thermostat comes in many different models. Mechanical thermostats are set to a single temperature and remain at that temperature unless manually changed by the homeowner. Programmable thermostats can have multiple settings depending on the type and manufacturer, and can help control energy expenses by limiting use of your heating and cooling system when nobody’s home.
Types of Thermostats
- Mechanical thermostats – The temperature is set by hand manually. This is a basic and inexpensive option. If you haven’t upgraded your home’s thermostat in the past 10 years, it’s probably the type in use now.
- Digital non-programmable thermostats – The temperature is set manually, but there is a LCD display. If you want to change the setting, you have to do it yourself.
- 7-Day programmable thermostat – The flexible programming allows you to program different settings for different days of the week. It’s also possible to schedule up to four settings per day. If you have an irregular schedule, this is a good option.
- 5+2 Day thermostats – Weekdays use the same programming, but a different schedule can be used for weekends.
- 5+1+1 Day thermostats – Saturdays can have a different schedule from Sunday with the 5+1+1 thermostat. Weekdays may be programmed with another setting.
The savings on energy costs are significant with a properly operated programmable thermostat. The extra cost of installation easily pays for itself over time. If your home has multiple-zone heating and cooling, a separate thermostat for each zone is the ideal situation.
Modern thermostats come with special features. Here are some of the extras that you may find attractive when choosing a thermostat:
HVAC Thermostat Extra Features
- Touch-screen controls – This feature is mainly available with programmable thermostats and can be a time-saver when using multiple settings.
- A backlit display – The backlit display can be useful if your thermostat is located in a low light area or for night operation.
- Indicator lights – This can be a useful option to signal if a battery or furnace filter change is necessary.
