Sometimes my wifi Honeywell thermostat gets a day behind for an unknown reason. Here's how to set it back.
- Select System
- Press and Hold Fan
- Should see 0120 with setting 20 blinking
- Press next to 0130, this is the year
- Press next to 0140, this is the month
- Press next to 0150, this is the day
- Press Done.

Thanks, kris!!!!! Was ready to replace. Awesome info.
If you happen to have the RTH-6500, the solution is different. You have to log on to your Honeywell account online and update your Settings for the thermostat. Specifically, the Location. Change the time zone to something different, Submit the change and then change back to your proper time zone and Submit the change. Don't forget to check the Daylight Savings Time box if applicable. I also did the same thing with my Zip Code.
That did the trick for me.
Important Note: It was incredibly frustrating finding the right Settings menu. I selected My Account –> Add Location, then immediately Hit the Cancel button. This will bring up your configured thermostat and location. On the right side you will see a Settings Icon. Click that and make the changes as noted above.
Tim –
You are awesome. I wish I searched here earlier. I had this problem with T-stat at office. Spend a LONG time with HW support. never resolved. Finally just bought different thermostat. But then the same thing happened at home (same T-stat, same app). This time I came across this blog. I tried your tip: change location settings then change back. Now it works fine again.
Thanks again for taking the effort to post and help the rest of us!
