Light-emitting diodes (LED) on front panel
The LED’s on the front panel will light up when the relevant relay
is activated.

The light-emitting diodes will flash when there is an alarm.
In this situation you can download the error code to the display
and cancel/accept for the alarm by giving the top button a brief
push.
The buttons
When you want to change a setting, the upper and the lower
buttons will give you a higher or lower value depending on the
button you are pushing. But before you change the value, you
must have access to the menu. You obtain this by pushing the
upper button for a couple of seconds - you will then enter the col-
umn with parameter codes. Find the parameter code you want to
change and push the middle button until value for the parameter
is shown. When you have changed the value, save the new value
by once more pushing the middle button.
