Let's try resetting a Honeywell Thermostat
Power off the thermostat and remove the batteries. Put the batteries in the wrong way, with negative to positive and positive to negative. Wait ten seconds and put them back in the correct way. Your thermostat will be reset to factory settings.

Once you see the number 5
You would need to change it to "1" using the "-" button
Then press Select.
Then following the same instruction you would need to change it to "2"
Then press Select.
Repeat this process to enter the second through fourth digits of the number.
So eventually it will be 12345 on the screen
Then you would need to press Select again.
