10.16 Setting the parameters at the control panel
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 these last-mentioned parameters. 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

: ‘Controlling options and settings’, page 82 ff.
IMPORTANT:
Do not change the parameters P2LC, P2LD, P2ML, P2MM and P5BI; they serve different purposes
than CH control. Changing these parameters may affect boiler operation negatively
.
