I became locked out of my honeywell th8110r1008 thermostat while trying to set the password, how can i unlock/reset it

Here's an actual solution:



Try using the Date Code above the QR on the back of the panel. If it doesn't work, you add 1234 to the date code. There is no setting a custom password, so It will only ever be these two options.
