[Must Be 4 Digits]
The System Manager has two levels of user access.
Level 1 users are limited to viewing or changing Zone
Temperatures and their Heating and Cooling Setpoints and to
viewing Unit ID numbers for those in alarm conditions.
Level 2 users have complete system access. Any status or
setpoint field can be read or reset from the Auto-Zone system.
These two levels of passcodes are programmable by any Level
2 user. The default Level 1 passcode is 1111, and the default
Level 2 passcode is 2222.
The actual digits in your passcodes are never displayed. An "X"
is used as a place holder for each digit entered. Passcodes must
always be four digits in length, so the useable range of numbers
is 1000 to 9999.
