In Segment One we learned the difference between older analog thermostats and newer digital thermostats. We touched on WHY digital technology has found its way into thermostats; primarily to facilitate programmable features.
But, do you really need a programmable thermostat? The answer isn’t as easy as you would think; which is why I get asked this question so often.
Features and benefits of programmable and non-programmable thermostats:
Non-Programmable: Not many features outside of the normal duties of a thermostat which is to control your equipment. However, some things are worth mentioning.
Programmable: Feature and Benefit rich! In addition to the above features, programmable thermostats also:
When considering the features of a new thermostat remember, what may translate into a benefit for one person may not be a benefit for another person! What are the benefits of a programmable schedule? The main benefit is decreased energy usage while still maintaining comfort. How? By using the programmable schedule, for example:
As you can see from the above example, during those times we are home the temperature is 74°, when we leave for work it is 80° and while we sleep it is 76°. By adjusting the set points higher (called setback) when we are not home the equipment does not run as much thereby saving energy, wear and tear on the equipment and, ultimately, money. At the same time, anytime we are home the temperature is just what we want it to be.
So, can you benefit from a programmable thermostat or not? The answer is almost always yes, with one big exception. If you, or anyone, are home all day long there may be no great benefit in a programmable thermostat. Talk to your HVAC Professional, they can help you make the correct decision for your lifestyle.
Next segment we will explore the ‘additional features’ of thermostats available today.
