10.15 Setting the parameters with the display menu
The functions of the controller are embedded in de electronics. The values and settings that are being used for
these controlling functions can be changed by programming these values. This can be done by a skilled and
trained service engineer with the help of a computer, the correct software and an interface cable. The values and
settings that are used for these controlling functions are called parameters. A selection of these parameters can
be programmed on the unit itself, without the use of a computer. These settings can easily be done at the control
panel of the water heater.
The following table gives a list of these 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 needs 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 above one can see 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 a reference of all relevant parameters which are shown in
the table above and can be set on the unit.
IMPORTANT:
Do not change the parameters P2LC, P2LD, P2ML, P2MM and P5BI ; they are present in the controller for diffe-
rent purposes than DHW control. Changing these parameters may affect water heater operation negatively !
