How to Change Batteries in a Honeywell Thermostat Step by Step
Changing a thermostat device’s batteries isn’t a tough task to do. However, due to the importance of the device in many homes, you might want to be very careful in completing such a chore.
So to help you with that, we’ll break down the steps in how to change thermostat battery, especially for Honeywell models.
1. Determine the model of the thermostat you own
The very first thing that you have to know is which thermostat model you own. This is extremely important to do as Honeywell’s thermostats are designed and configured in different ways.
In some models, the battery compartment is easy to remove from the main unit. In others, you’ll need to take out the entire unit from its mount before you can access the batteries.
2. Check the product manual
If you’re the one who bought and installed the Honeywell thermostat in your home, then you can refer to the product manual instead to start learning about its battery-replacement process.
(For example check this manual).
These product inclusions will contain the official information about the Honeywell product that you own, so you can be sure that you’ll be able to swap out the batteries of your unit without a hitch.
However, if you don’t have the manual on hand, you can just look it up online.
Lots of websites store and display the manuals of various products and there are also countless video tutorials available, so you might get lucky and find the one you have at home.
If you still end up with nothing, then check if your unit is either a sliding or non-sliding variety.
Non-sliding Honeywell thermostats have removable battery compartments while sliding ones require whole unit removal to access their battery compartments.
Once you have this information, you can proceed to the next step.
3. Turn off your thermostat
If your battery still has some juice left, turn off the device before you start handling it.
This way, you won’t disrupt its mechanisms and will help you make sure that it gets to save its settings properly, if possible.
Most Honeywell models will get their clock settings reset when the batteries are changed but the general settings you’ve selected should be intact.
4. Follow these steps on how to change the battery in Honeywell thermostat based on their compartment design
For non-sliding wall thermostats:
- Locate the battery compartment. It’s often not marked but it shouldn’t be hard to find. Its tab is typically located on one side, at the top or bottom of the device and normally has a ridged area to provide users some traction when removing the part.
- Once you find the ridged area, you will either need to press on it or press and slide out or swing out the tab to take out the battery compartment from the main unit. Be careful with this, as some battery compartments are attached to the main body of the device.
- Remove the old batteries and replace them with fresh ones accordingly.
- Place the battery compartment back into its slot then power up the device to check if you’ve installed the batteries properly. Select your chosen settings and you’re good to go.
- Dispose of the old batteries properly.
For sliding wall thermostats:
- Look for the locking mechanisms of the wall plate and the faceplate of the device so you’ll know which direction to slide the device towards.
- Once you found it, grab hold of the unit and push or pull according to the configuration of the device.
- Slide the faceplate out of the backplate carefully.
- Turn it over to access the battery compartment. If the battery compartment is covered, remove it then take out the batteries. Replace them with new ones.
- Turn the thermostat’s faceplate over again then slide it back to place carefully. Snap it into place with care to avoid any locks from breaking.
- Power the device on then select your desired settings.
This is usually how to change the battery in old Honeywell thermostats, so you might want to take a closer look at these steps if you’ve only inherited your thermostat from the previous owners of your house or apartment.
Important Reminders When Changing Thermostat Batteries
To make sure that you know how to replace the battery on Honeywell thermostats properly, keep these tips in mind as well:
- Do not yank the removable parts forcefully if they’re stuck in place. There’s a very good chance that wires and other stuff could be in the way, so for your home’s safety, refrain from using a lot of force when taking out faceplates or removable battery compartments.
- As much as possible, try to locate the official manual of your thermostat if you don’t have a physical copy of it. This way, you’ll get official information and instructions which can then minimize the odds of you mishandling your device.
Changing Honeywell Thermostat Battery FAQs
How do I know if my thermostat needs a new battery?
Most Honeywell thermostats will display a “Low Batt” warning or a snowflake icon when the battery is running low. This typically occurs once a year, but you might still have around two months to replace the battery after the first warning appears.
What type of batteries do Honeywell thermostats use?
Honeywell thermostats commonly require AA or AAA batteries. It’s a good idea to check your specific model’s battery compartment to confirm the size and number of batteries needed.
Do I need to reset my thermostat after changing the batteries?
After replacing the batteries, some models might require a reset. This can often be done by turning the thermostat off at the breaker, removing and reinserting the batteries, and then turning the power back on. Check if your model has a reset option in the control panel menu.
What if my thermostat shows a low battery warning even after I’ve replaced the batteries?
This could be due to the batteries not being installed correctly or the battery contacts needing cleaning. If the issue persists, try using a fresh set of batteries and ensure that they are correctly installed. If problems continue, a reset or a check for loose connections might be necessary.
What should I do if my thermostat isn’t working after changing the batteries?
If your thermostat isn’t working after a battery change, ensure the batteries are correctly installed and the display is active. If there’s still an issue, you might need to check for loose connections or consider a professional inspection, especially if the thermostat is under warranty.
How often should I change my Honeywell thermostat batteries?
It’s recommended to change the batteries in your Honeywell thermostat annually, or when the low battery indicator appears. This helps avoid any interruptions in thermostat function, which could affect your HVAC system’s efficiency and your home’s comfort especially when you need it!
Conclusion
Changing the battery in your Honeywell thermostat is a quick and easy task that you can do on your own without needing professional help.
