II.3.8 SETTING AND MODIFICATION OF
PARAMETERS WITH CONTROL PANEL
The parameter map is resident in the touch control panel or on-board
control panel: when this is connected to the base card, overwriting from
the control panel to the base card takes place.
For the setting and modification of the parameters it is therefore
necessary to have a control panel (a KPLT touch wall panel can be
used or the on-board display provided on the KCF / B kit).
The procedure is as follows:
Press the Fan and On / Off
button on the control panel
simultaneously for 5 seconds.
The indication InS appears on
the display.
Press the On / Off button.
Use the UP / DOWN keys to
enter the password (15) and
confirm with the On / Off key.
The indication "P00"
(parameter number Pxx)
appears on the display.
Using the UP / DOWN key
scroll through the parameters
until you reach the desired
parameter whose value you
wish to change.
Press the On / Off button.
The parameter value can be
changed with the UP / DOWN
keys. Confirm with the On / Off
button.
To exit programming, wait 15 seconds or press the Fan button.
