The following table gives a list of parameters that can be programmed by the display. All parameters that are shown in the display can be
changed. NOTICE: Only the password for level 1 is issued in this manual. When other "more advanced" parameters need to be programmed,
it can only be done by a skilled and trained service engineer, who has access to level 2.
In the parameter table shown below are all the parameters that can be set on the unit without the use of a laptop/computer.
In the following chapter "Controlling options and settings" the controlling options for hot water and cascading are explained. In the explanation
of these options there is reference to all relevant parameters which are shown in the table below and can be set on the unit.

IMPORTANT:
Do not change the parameters P2LC, P2LD, P2ML, P2MM and P5BI; they are used within the controller for
purposes other than DHW control. Changing these parameters may affect water heater operation negatively!
