Help for a locked screen on a Honeywell TH8320 thermostat


My new Honeywell thermostat shows screen locked at all times. It was just installed Friday. After coming home from the weekend it is so hot and the screen display says "screen locked" the whole time. I have removed the face plate and taken out batteries and reinstalled. Now what? Please help

Go to the section Advanced Settings and this should walk you through unlocking the screen

This is from the 8320U/8321U manual that I have.

Good Luck

Keypad
Lockout
Installer Setup #0670
0 = Unlocked
1 = Partially Locked
2 = Fully locked

Unlocked: all functions are available.

Partially locked:only temperature up and down keys and
ability to enter and modify Installer Setup mode are available.

Fully locked: only ability to enter and modify Installer
Setup mode are available.
