How to Set Up Honeywell Home T6 Pro Smart Thermostat
Troubleshooting
If the thermostat screen is blank:
• Check the circuit breaker or fuse that’s connected to your heating or cooling system and turn it on if it’s switched off.
• Make sure the power switch at the heating or cooling system is on.
• Make sure the furnace door is closed securely.
If the screen is difficult to read:
• Increase screen brightness (see page 22 for instructions). If the heating or cooling system isn’t responding:
• Touch Mode on the thermostat home screen and set the system to Heat. Make sure the temperature set point (the smaller of the two numbers) is higher than the indoor temperature (the large number in the center of the screen).
• Touch Mode on the thermostat home screen and set the system to Cool. Make sure the temperature set point (the smaller of the two numbers) is lower than the indoor temperature (the large number in the center of the screen).
• Check the circuit breaker or fuse that’s connected to your heating or cooling
system and turn it on if it’s switched off.
• Make sure the power switch at the heating or cooling system is on.
• Make sure the furnace door is closed securely.
• After making these changes, wait 5 minutes for the system to respond.
If the temperature setting doesn’t change:
• Make sure the heating and cooling set points are within the operating range.
– Heat: 40 ºF to 90 ºF (4.5 ºC to 32.0 ºC)
– Cool: 50 ºF to 99 ºF (10.0 ºC to 37.0 ºC)
If Cool On or Heat On is flashing:
• The compressor protection feature is engaged. Wait a few minutes for the system to safely restart to avoid damaging the compressor. See page 9 for more information.
FAQ
WiFi connection questions
Q: Will the thermostat still work if the WiFi connection is lost?
A: Yes, you can still manually adjust the temperature at the thermostat. However, some features such as location-based temperature control (geofence technology) can only be managed through the Resideo App and will not function without a WiFi connection. The thermostat will automatically reconnect to WiFi once the network is restored.
Q: Why is the thermostat not finding my WiFi network?
A: The T6 Pro Smart thermostat operates in the 2.4GHz range. Smartphones operate in both the 2.4 and 5.0 GHz ranges, so your smartphone may “see” your WiFi network when your thermostat does not. Most WiFi routers will broadcast two networks: 2.4 GHz and 5.0 GHz. If you have an option, make sure your smartphone is connected to the 2.4 GHz network.
Q: Is there a way to extend the strength of my WiFi signal?
A: The range (distance) of your WiFi signal is determined by your router. Try moving your router closer to the location of the thermostat, or use a router with a stronger signal range.
Q: There’s an alert that says “WiFi Signal Lost” – what should I do?
A: Wait 5 minutes for the thermostat to reconnect or select an alternate network (if you have one) in the Resideo App configuration menu. If the thermostat isn’t able to reconnect, you’ll need to troubleshoot the router to determine the cause.
Q: Why is there an offline symbol (WiFi icon with a strikethrough) in the upper-right corner of the thermostat screen?
A: The thermostat has lost its connection to the WiFi network. First, make sure your WiFi router is plugged in and broadcasting a signal. If it is, try resetting the router (consult the router’s manual for instructions). When the WiFi network has been restored, the thermostat will automatically reconnect.
Home account and app questions
Q: Why haven’t I received an account activation email?
A: If you haven’t received an activation email after 5 minutes, check your Spam folder and look for an email from Connected-Home@alarmnet.com. If you don’t see it, tap Resend to have the activation email resent. If you still don’t receive it, please contact the Technical Support team at 1-800-633-3991.
Q: Can I set up my thermostat with multiple users?
A: Yes. To add users, log into the Resideo App and tap the menu icon in the upper-left corner. Select Add Users, tap add user and type in the email addresses of the people you’d like to invite. If they already have a Home account set up, the thermostat and its location will automatically be added to their account. If they don’t have an account, they’ll receive an email prompting them to download the Resideo App and create a new account.
Q: Can I set up location-based temperature control with multiple users?
A: Yes. Location-based temperature control (geofence technology) will activate based on the last person who leaves and the first person to return. Each user will need to create their own Home account with a login ID and password. Two users should not share the same account. Each user will then need to enable location-based temperature control. See page 13 for instructions.
