How to Reset a Honeywell Thermostat: Quick and Easy Guide

Whether you’re experiencing technical issues, changing batteries, or just wanting to get a clean start, understanding how to reset your Honeywell thermostat is essential for maintaining the efficiency of the heating and cooling system in your home.

Most Honeywell thermostats can be returned to factory settings by removing the batteries, putting them in backward for 10 seconds, then reinstalling the batteries properly. Resetting only the schedule, WiFi, or HomeKit functionality or factory resetting an AC-powered unit requires a method unique to the type of thermostat in your home.

Keep reading for the basic steps to resetting most Honeywell thermostats, a guide to the particulars for many of the brand’s top devices, and some common troubleshooting tips should any issues arise.

Resetting your Honeywell thermostat

When it comes to resetting a Honeywell thermostat, the company has kept things relatively straightforward and easy to follow – though, thankfully, difficult to do accidentally!

There are several reasons you may decide it’s time to return your thermostat to factory settings, including a malfunctioning thermometer, the thermostat not coming on after changing the batteries, or even the HVAC system simply isn’t doing its job and either not heating or cooling your home. Before you wipe out everything on your thermostat, take a moment and decide which kind of reset you need.

Depending on your Honeywell thermostat, you may be able to perform four kinds of resets:

• Schedule reset
• WiFi reset
• HomeKit reset
• Factory reset

Keep reading to find out which one is the best place to start when resetting your thermostat, and how to perform this operation on most Honeywell thermostats.

Honeywell thermostat not cooling? If resetting your thermostat doesn’t work, here are 8 other troubleshooting tips!

Schedule reset

Probably the most basic reset option is the schedule reset. This is especially useful if you’re experiencing errors with your thermostat or only want to change a day or two.

A schedule reset will reset your programmed schedule for any given day, returning the program to its factory settings. This won’t affect any other settings on your thermostat.

Depending on your thermostat model, you may need to perform the reset action for each day or programming period available.

WiFi reset

Just like you occasionally need to reset your phone’s connection to your home WiFi, you may need to perform a WiFi reset on your thermostat. Obviously, this will only be necessary (or possible) on WiFi-enabled devices.

This process will disconnect your thermostat from the current WiFi network, allowing you to reconnect it to a new network or reset the existing connection.

This can be helpful if the thermostat and the app are not synching up properly, or if you are installing a new WiFi network.

HomeKit reset

A HomeKit reset may occasionally need to be performed on Honeywell thermostats that are connected to the Apple HomeKit system.

Resetting a HomeKit connection can be done either from your iOS device or the thermostat itself. Either way, you’ll need to reconnect the thermostat as if it’s a new installation.

Make sure you have the manufacturer’s installation information available before you do a HomeKit reset or you may find yourself with a non-functional central heating and air system.

Factory reset

While most of the resets discussed pertain to specific Honeywell thermostats, all models will be able to perform a factory reset, although the specific methods will vary.

Performing a factory reset on a Honeywell thermostat will return it to its original factory settings, including wiping out the time, schedule, WiFi, and any other connections that have been made since installation.

A factory reset can be a very helpful troubleshooting step and can, in fact, save you from having to replace the entire thermostat, but it shouldn’t be your first choice unless you really enjoy programming your thermostat’s schedule.

A factory reset can be performed on many Honeywell thermostats by removing the batteries and replacing them backward. Let them sit for at least ten seconds, then take them out and put them back in properly.

Many of the newer Honeywell thermostats require direct power and don’t need batteries (although they may be installed as a backup), so this method won’t work. I’ve included a guide for performing resets on Honeywell’s most popular devices further down; find your specific model and follow the specific steps to reset your thermostat.

Can I do a reset on my Honeywell thermostat?

Most Honeywell thermostats can be reset by reversing the batteries for 10 seconds then returning them to their proper position; however, this doesn’t work for thermostats that aren’t battery-powered. It makes sense that you can’t do a WiFi reset on a thermostat that isn’t WiFi-enabled, but how do you know the best way to perform a reset on your specific model of thermostat?

The best way to know which reset you can perform (and how) on your Honeywell thermostat is to check the manufacturer’s directions.

In general, here are the types of resets that can be performed on the most popular Honeywell thermostats:

Model	Manual factory reset	Digital factory reset	Schedule reset	WiFi reset	Apple HomeKit rest
5-1-1	yes	no	no	no	no
7-day	yes	no	no	no	no
VisionPro 8000	yes (if not on common power)	yes	yes	yes	no
T5	no	yes	yes	yes	yes
T6	no	yes	yes	yes	yes
T9	yes (if not on common power)	yes	yes	yes	yes
T10	no	yes	yes	yes	yes

Resetting a Honeywell 5-1-1 thermostat or 7-Day Programmable Thermostat

The Honeywell 5-1-1 (RTH7460D1000) and 7-Day Programmable (RTH7560E1001) thermostats are staples of the Honeywell Home line. They are both fairly utilitarian, being programmable but not “smart” or WiFi-enabled.

This thermostat is easy to reset as it only has one option: the factory reset. While the manufacturer’s directions do not include instructions on how to do this, many Honeywell thermostats can be reset by following these directions:

• Remove the batteries.
• Put them back in backward, and leave it that way for 10 seconds.
• Remove the batteries and put them back in properly.

If this method doesn’t work, Honeywell recommends contacting their customer support line. Be sure to have your specific model number ready.

These directions apply to all thermostats in the RTH7400 and RTHT7500 series.

Resetting a Honeywell Pro 2000 Series Thermostat

The Honeywell Pro 2000 Series is a basic thermostat that is about half a step up from the 5-1-1 or 7-Day models. The primary distinction is that the Pro 2000 includes a setting for Emergency Heat, meaning it can use an auxiliary heating system when the primary heater isn’t functioning.

This thermostat is available in both horizontal and vertical configurations. The operating procedures are the same for both models.

As with the 5-1-1 and 7-Day thermostats, you’ll need to perform a factory reset on this model in order to reset the schedule. Remove the batteries, put them back in backward, and leave them for 10 seconds. After that, you can remove the batteries and put them back in properly.

The thermostat should be returned to its default settings, and the time and schedule will be cleared.

These directions apply to Honeywell thermostats in the Pro 2000 series, including the TH2110DH, TH2210DH, TH2110DV, and TH2210DV. I have the Honeywell RTH2300B1038 and the method is the same for it as well.

No other resets are necessary for this model.

Final thoughts on resetting a Honeywell thermostat

Honeywell is one of the leading providers of commercial and residential thermostats and has various models available.

All Honeywell thermostats are relatively easy to use, although various functionalities may need to be cleared occasionally if the schedule or the temperature sensor becomes inaccurate or if the WiFi or HomeKit connection becomes unstable.

If you still have the manufacturer’s directions, consult them for how to clear the settings on your thermostat. If you don’t, you’ll need to determine the model number by checking the back of your thermostat.
