Operation

Operation of the controller can take
place via data communication or from a
separate display. Operation via data
communication may be performed via
the AKM programme and a text that
can be seen in the earlier section
"Survey of functions". Operation from
EKA 162 is described below:

The buttons (EKA 162 only)
When you want to change a setting, the
two 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 column with
parameter codes. Find the parameter
code you want to change and push the
two buttons simultaneously. When you
have changed the value, save the new
value by once more pushing the two
buttons simultaneously.

Temperature setting

When it is the temperature setting you
wish to change, do not enter the menu.
Push both buttons simultaneously and
you will be allowed to change the
temperature reference when the display
answers back by flashing.

Forced control

In addition to the normal way of operat-
ing the controller you are now able to
perform a number of forced control
functions which you start, as follows:
- Cut out alarm relay / check alarm code
- Read the defrost stop temperature
- Manual start or stop of defrost
Or examples put in another way:
