Light-emitting diodes (LED) on front panel
There are four LED’s on the front panel which will light up
when the relays are operated.
All LED’s will flash if there is an error in the regulation. In this
situation you can upload the error code on the display and
cancel the alarm by pushing the top button briefly.
Display
The values will be shown with three digits, and with a setting
you can determine whether the temperature are to be shown
in bar or in psig.
Operation Menu survey
The buttons
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.
