Fault message
In an error situation the LED's on the front will flash and the alarm relay
will be activated. If you push the top button in this situation you can see
the alarm report in the display.
There are two kinds of error reports - it can either be an alarm occurring
during the daily operation, or there may be a defect in the installation.
A-alarms will not become visible until the set time delay has expired.
E-alarms, on the other hand, will become visible the moment the error
occurs.
(An A alarm will not be visible as long as there is an active E alarm).
Here are the messages that may appear:

Operating status
The controller goes through some regulating situ-
ations where it is just waiting for the next point
of the regulation. To make these "why is nothing
happening" situations visible, you can see an op-
erating status on the display. Push briefly (1s) the
upper button. If there is a status code, it will be
shown on the display. The individual status codes
have the following meanings:
Normal regulation
Waiting for end of the coordinated defrost
When the compressor is operating it must run for
at least x minutes.
When the compressor is stopped, it must remain
stopped for at least x minutes.
The evaporator drips off and waits for the time to
run out
Refrigeration stopped by main switch. Either with
r12 or a DI-input
Refrigeration stopped by thermostat
Defrost sequence. Defrost in progress
Defrost sequence. Fan delay — water attaches to
the evaporator
Refrigeration stopped due to open ON input or
stopped regulation
Door is open. DI input is open
Melt function in progress. Refrigeration is inter-
rupted
Modulating thermostat control
Emergency cooling due to sensor error *)
Manual control of outputs
Case cleaning
Delay on outputs during start-up
Case shut down
Other displays:
The defrost temperature cannot be displayed.
There is stop based on time
Defrost in progress / First cooling after defrost
Password required. Set password
Regulation is stopped via main switch
*) Emergency cooling will take effect when there is lack of signal from a
defined S3 or S4 sensor. The regulation will continue with a registered
average cutin frequency. There are two registered values – one for day
operation and one for night operation.
