My thermostat does not show “Sched” or “Hold” buttons. Why?

If the thermostat is set for operation as a non programmable unit then it will not show Sched or Hold in the display. To check how the thermostat has been set up, please refer to the owner’s manual under Advanced Functions and refer to feature 0160.

My thermostat shows humidity however I am unable to change it?

If the VisionPRO Thermostat does not allow you to change the humidity settings, then it is not setup for dehumidification or humidification control. In this case Honeywell recommends speaking to the installing contractor of the thermostat.

Why isn’t my thermostat connecting to my Wi-Fi router even though it is

very close to the thermostat?

Please check a few steps first, in order to make sure that your router can be “seen” by your thermostat:

Your router is powered and broadcasting the Wi-Fi signal in the 2.4GHz range.
Your thermostat is not in a place with poor signal from the router. For example, most homes have “dead spots” where Wi-Fi signals are unreliable.
Your thermostat “sees” and connects to the home network, not a guest network. If you must connect to your guest network, you will need to unblock port 443 in the guest network firewall.

Why is my thermostat’s Wi-Fi not working?

If your thermostat’s Wi-Fi isn’t working, the solution depends on what you’re experiencing.

What are you experiencing?

NEW THERMOSTAT, NEW INSTALLATION – This is for people who recently bought a new thermostat and are installing it for the first time. Continue to the New Thermostat, New Installation section.
OLD THERMOSTAT, NEW INSTALLATION – This is for people who have an existing thermostat but are moving it to a new location. Continue to the Old Thermostat, New Installation section.
LOST WI-FI ON APP/ THERMOSTAT – This is for people who have an existing thermostat that was working but has lost connection. Continue to the Lost Wi-Fi on App/Thermostat section.

New Thermostat, New Installation

1. Which app does your thermostat work with?

HONEYWELL HOME APP – Compatible thermostats include T-Series and Round Smart Thermostats. Continue to the Honeywell Home subsection.
TOTAL CONNECT COMFORT APP – Compatible thermostats include Wi-Fi FocusPRO, VisionPRO, Prestige and Wi-Fi programmable thermostats. Continue to the TCC subsection.

THERMOSTAT REGISTRATION – See the Registration Issues FAQ.

App-Thermostat Pairing Issues

3. Make sure your app is up to date, and your mobile phone is within 3-5 feet of your thermostat.

4. Make sure thermostat is broadcasting to your app.

In your app, you should see “Lyric XXXXXX” as an option to connect to.

5. Go to your phone’s settings and forget other networks. (This ensures the phone does not automatically “jump” back to a known wi-fi network, which can disrupt the connection process)

6. Is your app pairing with your thermostat now?

YES – Congratulations! You’ve fixed your Wi-Fi issue!
NO – Contact Support at 1-800-633-3991 or find a pro-installer in your area.

Thermostat-Network Pairing Issues

7. Turn off your mobile phone’s cellular/mobile data. (This ensures that the connection and registration app data goes to Honeywell / Resideo via the same route as thermostat data)

8. Turn on your mobile phone’s Wi-Fi.

Connect your phone to the same network that you’re connecting your thermostat to. (Typically, your home wi-fi network. If you are attempting to connect /register the thermostat via a mobile hotspot, your mobile phone and thermostat should connect to the same hotspot network)

9. Make sure the device you are connecting is on the same Wi-Fi network as the mobile device.

“Forget” all other networks, and turn off mobile data.
OR
Turn on “Airplane Mode” and then turn on Wi-Fi and connect to the same Wi-Fi network the thermostat will be connected to.

10. Make sure the network is a standard home network and does not require logging in from a web page, such as a guest network or business network.

11. Make sure you’re connecting to a 2.4 gigahertz (GHz) network with its own network name. (Only the T9/T10 thermostats, C2 Camera, and Smart Home Security base station are compatible with 5GHz networks at this time)

This specifically speaks to “Dual Band” routers which support both 2.4 GHz and 5 GHz networks.
Many of these routers will allow you to configure separate Networks to connect to on your phone or computer.
These networks must be named discretely (HomeWiFi – 2.4 and HomeWiFi – 5) in order for Honeywell Home products to connect.

12. Make sure you’re connecting directly to a router, and not a router accessory.

Examples of router accessories include repeaters and signal boosters.

13. Make sure your router hasn’t reached its max number of devices.

Routers typically can only handle a specific number of devices. Refer to your router support or Internet Service Provider for assistance.

14. Make sure your router is using Dynamic Host Configuration Protocol (DHCP).

When a router is using DHCP, it automatically assigns internet protocol (IP) addresses to each device. Honeywell connected devices work best with DHCP.

15. Make sure your router isn’t using any advanced security settings such as after-market firewalls, or connected to any network device, such as a switch or gateway which may have its own security.

Make sure Wi-Fi network is using one of the following security protocols. Other security protocols are not recommended. • OPEN • WEP PSK • WPA TKIP PSK • WPA2 AES PSK • WPA2 MIXED PSK.

16. Reset your thermostat.

Power cycle the device for 30 seconds or perform a hard reset by pressing and holding the reset button for 30 seconds. This clears short term memory. Power cycle the router for 30 seconds. This clears short term memory and resets router tasks.
