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 cor-
rect 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 is-
sued in this manual. “More advanced” parameters need to be programmed by a skilled and trained service engi-
neer with access to level 2.
When
‘Modify = no’, the parameter can only be programmed at level 2

: ‘Controlling options and settings’, page 78 ff.
IMPORTANT:
Do not change the parameters P2LC, P2LD, P2ML, P2MM and P5BI; they are present in the control-
ler for different purposes than CH control. Changing these parameters may affect boiler operation negatively
