Operation; Temperature Setting; Menu Survey - Danfoss EKC 414A1 Instructions For Use Manual

Operation

Operation of the controller can take place via data communication
or from a separate display.
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 push-
ing. 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.
Or briefly:
Gives access to the menu (or cutout an alarm)
Gives access to changes
Saves a change

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 al-
lowed to change the temperature reference when the display an-
swers back by flashing.
Forced control
In addition to the normal way of operating 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
• Push the upper button
- Read the defrost stop temperature
• Push the lower button
- Manual start or stop of defrost
• Push the lower button for four seconds
Examples put in another way:
Set the temperature
1. Push the two buttons simultaneously
2. Push one of the buttons and select the new value
3. Push both buttons again to conclude the setting
Set a menu
1. Push the upper button until a parameter is shown
2. Push one of the buttons and find the parameter you want to
change
3. Push both buttons simultaneously until the parameter value is
shown
4. Push one of the buttons and select the new value
5. Push both buttons again to conclude the setting
