6.6 Setting mode service level (X00)

(only for the qualified service engineer)
To prevent accidental, unauthorised access by non-qualified persons the control sys-
tem requires an input code to gain access to the second level of boiler control.
- Press the 'm' - and 's'-keys simultaneously and hold. The 'code'-display now
shows a letter c with a random number in the t-display.
- While holding both keys pressed, set the t-display to 12, using the [+] or [-]-
keys and press the 'e'-key.
- The display will flash twice confirming acceptance of the access code.
- Release the keys and c12 will dissappear from the display. You are now in the
service mode
WARNING: changing factory defaults without reference to the tables contained in this
manual may result in incorrect operation.
- To delete the service code press the 'reset'-key once
- If no keys are pressed over a 15 minute period the service code will delete auto-
matically
