Thermostats

Learn about furnace thermostats

Furnace thermostats are an important part of your furnace. They allow you to measure the temperature level in your home and adjust the indoor climate as needed. Sometimes, you need to perform maintenance or adjust your thermostat so that it more accurately measures and adjusts the room temperature. Learn how to choose a thermostat that's right for you so that you won't have to worry about this essential part of your furnace.

Types of Thermostats

If you're looking to replace your thermostat, you can choose from these different types:

• Programmable thermostat. This type of thermostat allows you to enter temperatures and have them adjust automatically at a specified time. For example, if you want the heat to be lower at night, you can program your thermostat to automatically turn it down so that you don't have to remember to do it.
• Low-voltage thermostat. These are the most common types made by thermostat companies. For example, a Honeywell thermostat is low voltage and runs off of a transformer. The exact voltage you'll need depends on your furnace.
• Digital thermostat. These thermostats read and display temperature digitally. They sometimes also have a barometer built in.

Learning About Thermostat Installation

If you've got a new thermostat, here are some tips to teach you how to install it yourself:

• Remove your old thermostat. To do this, you must shut off your furnace's power supply, remove the thermostat to expose the wires, and disconnect the wires. Then, remove the plate from the wall.
• Pull the old wires through the new mounting plate and screw it onto the wall. Follow the manufacturer's instructions to screw it in properly.
• Connect the thermostat wires, using your owner's manual. Be very careful. If you're not sure how to do this, contact an HVAC contractor or the thermostat company.
• Attach your new thermostat securely.
• Set your heating thermostat to your desired settings.

If you are looking for a new thermostat, contact your furnace manufacturer. They may be able to recommend the best type of thermostat for your furnace, and point you to OEM parts so that you don't run into problems down the road.
