Button functions
The unit has 4 directly operable buttons. The two upper buttons 1 and 2 are freely programmable
as single-button or two-button functions. The two lower buttons 3 and 4 are used internally for
temperature shifting and cannot be configured otherwise.
If the temperature controller is set for "independent setpoints", the parameter "Function buttons
3/4 (-/+)" additionally provides the option of shifting the setpoints via "2Byte temperature setting".
Details, see chapter
By activating the
cleaning function
, it is possible to clean the glass surface without triggering any
functions. If at least 3 buttons are pressed simultaneously for more than 2 seconds, the 4 status
LEDs flash black and white evenly for 10 seconds. Now the buttons have no function. After the time
has elapsed, the unit returns to normal operation.

object is displayed in each case. The lock object locks the operation of the button(s) when a logical
"1" is received and releases it again when a logical "0" is received.
