Programmable thermostats offer more convenience and energy savings than manual models. If you want to get the most out of your new programmable thermostat, keep three key factors in mind: its compatibility with your cooling and heating system; its programming options; and its extra features.
HVAC system compatibility
The first thing to look for when choosing a new thermostat is compatibility. Here are a few common packaging terms that will help you shop, (but if you’re not sure if a particular model will work with your system, contact a heating and cooling professional for advice).
- One-stage heat or cool: These thermostats work with HVAC systems with separate heating and cooling units.
- Multi-stage heat or cool: These work with furnaces and air conditioners with multiple speed settings.
- Direct line voltage: These are compatible with homes that use 110- or 240-volt direct current power for the thermostat.
- 24mV: These rely on power from a transformer in the HVAC system.
- Battery powered thermostats: These don’t require hard wiring into your home’s electrical system.
Programmable thermostats come with differing levels of program customization. Here are the three common types to help you choose one that will work with your household’s schedule:
- Seven-day models: These models give you the most options, allowing you to set a different program for every day.
- 5+2-day models: These let you have one program for weekdays and another for weekends.
- 5+1+1 models: These let you set one program for weekdays, one for Saturday and a separate program for Sunday.
- One-week models: These let you set one program that runs all week.
Many new thermostats come with various other features that are designed for convenience and energy efficiency. While features such as backlit displays and voice-activated programming are not absolutely necessary, you should get the features that are important to you. Other handy features for a new programmable thermostat include: hold or vacation settings, furnace filter indicator and remote programming.
