Rail heat control
0=not used, 1=pulse control with timer function (o41 and o42), 2=pulse control
with dew point function
Dew point value where the rail heat is minimum
Dew point value where the rail heat is 100% on
Lowest permitted rail heat effect in %
Time delay from "open door" refrigeration is started
Definition of readings on lower button:
1=defrost stop sensor, 2=S6 sensor
Display of temperature
1= u56 Air temperature
2= u36 product temperature
Light and night blinds defined
0: Light is switch off and night blind is open when the main switch is off
1: Light and night blind is independent of main switch
Configuration of alarm relay
The alarm relay will be activated upon an alarm signal from the following groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input is activated for alarm
16 - Defrost alarms
32 - Miscellaneous
The groups that are to activate the alarm relay must be set by using a numerical
value which is the sum of the groups that must be activated.
(E.g. a value of 5 will activate all high temperature alarms and all sensor errors).
0 = Cancel relay function
Stop time for fan while night blind rolls down
Service
Temperature measured with S5 sensor
Status on DI1 input. on/1=closed
Actual defrost time (minutes)
Temperature measured with S3 sensor
Status on night operation (on or off ) 1=on
Temperature measured with S4 sensor
Thermostat temperature
Run time of thermostat (cooling time) in minutes
Temperature measured with S6 sensor
(product temperature)
Status on DI2 output. on/1=closed
Display air temperature. Weighted S3 + S4 (o17)
Measured temperature for alarm thermostat. Weighted S3 + S4 (A36)
Status on relay for compressor 1
Status on relay for fan
Status on relay for defrost
Status on relay for rail heat
Status on relay for alarm
Status on relay for light
Status on relay for compressor 2
Readout of the actual rail heat effect
1: Thermostat 1 operating, 2: Thermostat 2 operating
Status on high voltage input DI3
Readout of thermostats actual cut in value
Readout of thermostats actual cut out value
Readout of brine temperature S7
*) Can only be set when regulation is stopped (r12=0)
**) Can be controlled manually, but only when r12=-1
***) With access code 2 the access to these menus will be limited
Forced control
If you need to force-control an output, you should set r12 to -1 (manual
mode). You should then select the relevant relay function, e.g. u58. Go to the
function by pressing the middle button. Select On.

Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep upper and lower button depressed at the same time as you recon-
nect the supply voltage
Factory settings are indicated for standard units. Other code numbers
have customized settings.
