How Do I Manually Reset My Aprilaire Thermostat?

If you need to manually reset your Aprilaire thermostat, the first step is to locate the Reset button. This can usually be found on the back of your Aprilaire thermostat and should have a red Reset label printed near it. Once you’ve located this button, press and hold it for at least 5 seconds until all four lights on your unit begin flashing in sequence.

At this time, release the Reset button and wait for all lights to stop flashing before attempting any other functions such as setting temperatures or programming schedules. If done correctly, your system will now be reset to its factory settings with no prior changes retained. Additionally, if you experience any issues during the reset process or afterwards it’s recommended that you contact a qualified HVAC technician for further assistance in order to ensure proper operation of your unit going forward.

How Can I Troubleshoot My Thermostat?

Troubleshooting your thermostat can be a confusing process, especially if you’re not familiar with the basics of how it works. Fortunately, there are some simple steps that you can take to make sure that your thermostat is working properly. The first step is to check the power source for your thermostat.

Make sure that the battery has enough juice and that there isn’t any debris blocking its connection to the wall outlet or power strip. If these things check out, then it’s time to move on to more specific troubleshooting steps. Check all wiring connections between components in order to make sure they are secure and up-to-date; this includes checking for corrosion or damage as well as loose terminals and wires which could be causing intermittent electrical signals from reaching their destination devices.

Finally, test your thermostat by setting it at different temperatures and making sure that the furnace or air conditioner responds appropriately each time.

How Do I Get My Aprilaire Thermostat off Hold?

If you’re trying to get your Aprilaire thermostat off HOLD, it’s important to understand the basics of how this setting works. When in the “Hold” position, your thermostat will maintain a constant temperature regardless of any changes in outside air temperatures or weather. This can be useful for saving energy if you know that you won’t be home for an extended period of time and don’t want to waste energy cooling down an empty house.

However, if you do need to change the temperature again, getting it off HOLD is easy. All you need to do is locate the “hold” button on your Aprilaire thermostat and press it once. You should then see the current indoor temperature displayed instead of “HOLD”.

If not, try pressing hold again until the desired result appears. Now that your Aprilaire thermostat is no longer held at a constant temperature setting,you can adjust it as needed just like usual!
