Do You Know This About Digital Thermostats?

Published on February 21st, 2018

Digital thermostats

Digital thermostats are convenient and save money too. You can’t ask for two better features in a digital thermostat!

Digital thermostats are totally a guy thing and not the most glitzy gadget to talk about. I get it. It may be hard to convey just how cool these gadgets really are for homeowners. But as Joe Friday once said, “Just the facts, ma’am,” I will share the facts. Hopefully, the following facts will show you how terrific these techy gadgets are in keeping you comfortable consistently and saving you some of your hard-earned money.

Digital Thermostats Described

Digital thermostats have many cool characteristics worth pointing out.

  • Temperature is measured without any moving parts.
  • They rely on thermistors or other semiconductor devices such as a resistance thermometer or a resistance temperature detector. (There’s a lot more about techy stuff about thermistors to read here).
  • One or more regular batteries must be installed for a digital thermostat to operate, but 24 volt AC circuits are used as a power source for what some call “power-stealing” digital thermostats.
  • An LCD screen displays the current temperature and setting.
  • They provide comfort and energy conservation with clock, time-of-day and day-of-the-week settings for the temperature.
  • Some come with touch screens or the capability to work with home automation or building automation systems, better known as Smart thermostats.
  • Digital thermostats can control your HVAC unit with either a relay or triac (a semiconductor device).
  • Some come with a PID controller built in. Simply put, this means the PID controller will make sure the temperature is 70 degrees at say 6:30 a.m. instead of just clicking on at 6:30 a.m. and warming up the house to 70 degrees. And the neat PID controller makes sure that the temperature is very stable

Which Digital Thermostats Does Confident Aire Recommend?

We appreciate the quality and control of Nexia products. They make it easy to be in control of your home, even when you’re always on the go.

Programmable thermostats are the most common digital thermostats and can save around 30 percent on your heating bill. These energy savings come about because of their default programs; however, make a few adjustments to these defaults, and you could save even more. Be aware: there is the possibility that adjustments made to the defaults could reduce your energy savings.
