How To Set Your Programmable Thermostat

A programmable thermostat makes it easier to keep your home comfortable while using less energy. Instead of changing the temperature throughout the day, you can set a schedule that matches your routine. Learning how to set a programmable thermostat is simple, and once it’s programmed, your heating and cooling system can do most of the work for you.

Whether you’re at work, asleep, or relaxing at home, the right thermostat schedule can help keep your Erie home comfortable all year.

How To Set a Programmable Thermostat

Most programmable thermostats work in a similar way, even if the buttons or screen look different. Before you start, think about when people are usually home, away, or sleeping. Then create a schedule that fits your day.

Step 1: Set the Date, Time, and Mode

Before you start programming, check that the thermostat is set to the correct mode for the season:

  • Heat during the winter
  • Cool during the summer
  • Auto if your thermostat can switch between heating and cooling on its own

Next, confirm that the day and time are correct. Your programmed schedule depends on this information to run at the right times.

Step 2: Program Your Schedule

Most thermostats let you choose different temperatures for different times of the day, such as:

  • Wake up
  • Leave home
  • Return home
  • Bedtime

Set the temperature so your home is comfortable when you’re there and adjusts while everyone is away. If your weekends are different from your weekdays, many thermostats let you create separate schedules.

Step 3: Save Your Settings

Save your schedule and double-check that the times and temperatures are correct.

After a few days, see how your home feels. If it’s too warm or too cool at certain times, make small changes until you’re happy with the schedule.

Best Summer Thermostat Settings for Erie Homes

The best recommended thermostat settings during the summer depend on your comfort, but these are a good place to start:

  • Around 78 degrees when you’re home
  • Around 85 degrees when you’re away
  • A little warmer while you’re sleeping if you’re comfortable

Try not to lower the temperature too much when you get home. Your air conditioner won’t cool the house faster, and it may run longer than needed.

Using ceiling fans and closing blinds during the hottest part of the day can also help keep your home cooler.

Best Winter Thermostat Settings for Erie Homes

During the winter, these settings work well for many Erie homeowners:

  • Around 68 degrees when you’re home
  • A few degrees lower while you’re sleeping
  • Lower again when everyone is away

Don’t turn your heat completely off when you leave. Letting your home get too cold means your furnace has to work harder to warm it back up. If you’re going away for several days, keep the thermostat high enough to help prevent frozen pipes.

Avoid Common Programming Mistakes

Even the best programmable thermostat won’t work well if it’s not programmed correctly.

Some common mistakes include:

  • Changing the schedule every day instead of letting it run.
  • Setting the temperature much higher or lower, hoping the house will heat or cool faster.
  • Forgetting to update the schedule after a new job or school routine.
  • Leaving the thermostat on “Hold” without realizing it.
  • Making large temperature changes throughout the day.

If your thermostat isn’t following the schedule or your system isn’t working the way it should, thermostat troubleshooting can help find the problem. A technician can check the thermostat, wiring, and HVAC system to ensure everything is working together.

Benefits Of Smart Thermostats

A programmable thermostat is a great choice, but a smart thermostat offers even more features.

Many smart thermostats let you:

  • Change the temperature from your phone.
  • Learn your daily routine.
  • Adjust settings automatically.
  • Show energy reports.
  • Send maintenance reminders.
  • Connect with other smart home devices.

If your thermostat is old or you’re replacing your heating and cooling system, smart thermostat installation and replacement can make your home easier to manage while improving comfort.
