10.16. Setting the parameters with the display menu
The functions of the controller are embedded in de electronics by means of parameters. The values and settings
hereof can be programmed by a skilled and trained service engineer with the help of a computer (laptop), the
correct software and an interface cable. A selection of these parameters can be programmed at the control panel
of the unit itself, without the use of a computer.
The following table gives a list of all parameters that can be programmed at the control panel without the use of a
laptop/computer. NOTICE: Only the password for level 1 is issued in this manual. “More advanced” parameters
need to be programmed by a skilled and trained service engineer with access to level 2.
When ‘Modify = no’, the parameter can only be programmed at level 2

For extensive explanation see Ch. 11: ‘Controlling options and settings’, page 70 ff.
IMPORTANT: Do not change the parameters P2LC, P2LD, P2ML, P2MM and P5BI; they are present in the con-
troller for different purposes than CH control. Changing these parameters may affect boiler operation negatively .
