Locate the Aprilaire Thermostat Model Number

Before you reset your Aprilaire thermostat, you’ll need to find its model number. This number is essential because it tells you the exact thermostat version you’re working with, ensuring you follow the correct reset steps.

Start by checking the thermostat’s front panel or display screen; some models show the model number right there. If you don’t see it, gently remove the thermostat from its wall mount. Look on the back of the device or inside the battery compartment for a sticker or label.

The model number usually starts with “Aprilaire” followed by digits, like “Aprilaire 8620.” Once you’ve found this number, jot it down or take a photo.

With the model number in hand, you’re ready to proceed confidently with resetting your device.

Turn Off the Thermostat and HVAC System

Now that you’ve identified your Aprilaire thermostat model number, the next step is to turn off both the thermostat and your HVAC system.

Start by pressing the power button on your thermostat to switch it off. If your model doesn’t have a power button, set the system mode to “Off” or “Fan Only” to make sure it’s inactive.

Next, locate your HVAC system’s main power switch—often found near the furnace or air handler—and turn it off to cut power completely. This prevents any electrical issues while you reset the thermostat.

Turning off both devices is essential for a safe reset and helps avoid damaging the system. After powering down, wait a few minutes before proceeding with the next steps in the reset process.

Remove the Thermostat From the Wall Plate

How do you safely remove your Aprilaire thermostat from its wall plate? First, make sure the thermostat and HVAC system are powered off to prevent any electrical issues.

Locate the base plate holding the thermostat to the wall. Most Aprilaire thermostats simply snap onto this plate.

Gently grasp the thermostat body with both hands and pull it straight away from the wall. Avoid twisting or forcing it, as this could damage the connectors.

If you feel resistance, check for any screws securing the unit and remove them carefully with a screwdriver.

Once detached, set the thermostat down on a soft surface to protect its screen and buttons.

Now, your thermostat is free from the wall plate, ready for the next reset step.

Press and Hold the Reset Button

With the thermostat safely removed from its wall plate, you can access the reset button located either on the back or side of the unit. Look closely for a small, recessed button—often labeled “Reset.” You might need a pointed object like a paperclip or pen tip to press it.

Press and hold this button firmly for about 5 to 10 seconds. Keep holding until you feel a slight click or see the display respond, indicating the reset process has started. Don’t release the button too soon, as this can interrupt the reset.

Holding the button correctly guarantees the thermostat clears any errors or settings stored in its memory, preparing it for a fresh start. Once done, you can proceed to the next step confidently.

Wait for the Display to Clear or Change

After you press and hold the reset button, watch the thermostat’s display closely. You’ll notice the screen either clears completely or shows a change in the icons or numbers. This change signals the reset process is underway.

Don’t release the button too soon; keep holding it until the display responds as expected. If the screen remains unchanged after several seconds, you might need to try pressing the reset button again.

Once the display clears or updates, it confirms the thermostat’s settings have been reset to default. This step guarantees the system is ready for fresh programming or troubleshooting.

Be patient during this process, as rushing it could interrupt the reset and cause errors in your thermostat’s operation.

Reattach the Thermostat to the Wall Plate

Once the thermostat’s display confirms the reset, you can go ahead and reattach it to the wall plate. First, align the thermostat with the mounting brackets on the wall plate carefully. Make sure the connectors line up correctly to avoid damaging the pins.

Gently press the thermostat against the wall plate until you hear a click or feel it snap securely into place. Avoid forcing it, as the components should fit snugly with minimal pressure.

Once attached, give the thermostat a slight tug to ensure it’s firmly locked in. Proper reattachment is vital for the thermostat to function correctly and maintain a steady connection with your HVAC system.

Now that it’s securely mounted, you’re ready for the next step in setting up your Aprilaire thermostat.

Power On and Reconfigure Your Settings

Before you power on your Aprilaire thermostat, double-check that it’s securely attached to the wall plate to make certain proper connectivity. Once confirmed, press the power button to turn the unit back on. The display should light up, indicating the thermostat is operational.

Next, navigate through the menu to reconfigure your settings. Set your preferred temperature, system mode (heat, cool, auto), and fan settings according to your comfort needs. If your model includes scheduling options, input your daily or weekly temperature preferences.

Don’t forget to check the date and time settings to ensure your programmed schedules run correctly. After adjusting all settings, save your configuration and exit the menu.

Your thermostat is now reset, powered on, and ready to efficiently control your indoor climate.
