Last year we locked the screen on our commercial Carrier Debonair 220 themostat. Now we don't remember the key sequence to unlock it and it's cold. Can anyone help us?

Carrier does not use that model number. Check here

Carrier: HVAC Equipment > Thermostats (Residential)

There is such thing as a DEBONAIR 220... that's the one we have here at work.
I'm also trying to figure out how to unlock it.

I found the unlock pattern to unlock/ lock the controls... My job told me that this panels have been locked over 2years... smh... sad
But these instructions do work... Good Lucky

Instructions

1
Locate the "MODE" and arrow ("Up" and "Down") buttons on your Carrier thermostat control.

2
Press and hold down "MODE."

3
Press both the "Up" and "Down" arrow buttons simultaneously.

4
Wait a second. The "Locked" icon disappears from the screen. You can now use your Carrier thermostat as normal.
