Press the system button once and when you see the system and done displayed over the right and left buttons hold them both down for five seconds and that will take you to the setup menu, dont change anything in here just keep hitting the next button till you see the number 670 on the display, once you get to 670 just hit the up or down arrow until the number 0 is displayed next to the 670 your options are 0,1,2,3. after changing it to zero just hit done, you are now unlocked!

Honeywell Commercial PRO TB7220U Touchscreen Programmable Thermostat wont come off screen lock and we wanna turn on air conditioning... how do you shut off screen lock?


That one is fun. Touch the system cycle button. then touch the two spaces on both sides of the center button at the bottom hold them down at the same time. After 5-10 seconds the screen should flash and show numbers int the center of the screen touch the screen til the numbers 670 appear. then change the numbers beside it to 0. then click done. now you should be able to adjust temperature as needed
