- Wi-Fi password
- Router information
Accessing the Reset Menu
To start fixing your Wi-Fi, follow these steps:
- Find the thermostat’s control panel
- Press and hold the Fan button and Up Arrow at the same time
- Hold for exactly 5 seconds
- Go to option 39 in the system menu
Performing the Factory Reset
To reset your network, you’ll need to make a specific change:
Step | Action | Expected Result |
---|---|---|
1 | Change option 39 to 0 | Initiates factory reset |
2 | Press Done | Confirms reset command |
3 | Wait 1-2 minutes | “WiFi Setup” appears on screen |
Reestablishing Connection
After the reset, you’ll need to set up your Wi-Fi again. Choose your home network, enter the password, and wait for it to connect. Be patient, as it might take a few moments to get a stable connection.
Router Compatibility and Network Requirements

Setting up a reliable home network for your Honeywell thermostat is important. Not all wifi networks are the same. Knowing the right network setup can greatly improve your smart home experience.
When setting up your home network for a Honeywell thermostat, focus on these key compatibility factors:
- Router support for Dynamic Host Configuration Protocol (DHCP)
- Security protocols like WPA2 AES PSK
- Optimal frequency band selection
I suggest using a dual-band router for both 2.4GHz and 5GHz networks. The 5GHz band is faster, but 2.4GHz is better for range and wall penetration. This is key for homes with more space.
For your thermostat to work well, you need:
- A stable internet connection with at least 1 Mbps speed
- A router with modern security settings
- A consistent wifi signal across your home
Before setting up, check your router’s specs. Make sure it meets Honeywell’s network standards. This will help avoid connection problems and keep your thermostat working great.
