activation of functions while wiping the glass front.

2.2 Access Level
To prevent unauthorized or accidental changes to the sytem, the device has a
“locked” state. Typical use-case is public areas where it is not desired for any pass-
erby to change setpoint or control lights.
The device enters locked state on a timeout (no buttons tapped for a while).
Different installations may require different scenarios for locking or unlocking the
device. Therefore, the device can be configured to operate in 4 different access lev-
els. The allowed states and their sequence for each configuration are as follows:
• Default access level : Sleep << >>Operational
•Simple access level : Sleep << >> Display Only <<- key combination -
>>Operational
• Secure access level : Sleep << >> Display Only <<- enter passkey ->>Operational
•No Access Level : Sleep << >> Display Only
2.3 Activating The Screen
The device may switch to sleep or dark state, if no action is taken in a defined time
span. In this state screen appears to be black-out. Tap any key on the keypad to
activate the screen.
