Menu functions

Menu code Parameter description
cFg Configuration
Main switch
r12
With this setting refrigeration can be started, stopped or a manual override of the outputs can be allowed.
Stopped refrigeration will give a "OFF" signal on the display.
-1=service (manual control of outputs allowed)
0=OFF
1=ON
Predefined applications
o61
Predefined applications is to give the user an easy and fast way to configure the controller refer to a specific
application based on storage temperature, defrost type and defrost method.
Users can set appropriate application that meets their requirements under this menu (please refer predefined
applications table under section 2.4 for more details). Predefined application is protected by main switch.
Sensor type selection
o06
This parameter is for defining type of temperature sensors connected to the controller.
User can configure NTC 5 K, NTC 10 K, PTC and PT1000 sensors in this controller.
All the mounted sensors (Sair, S5 and Sc) must be of same type.
DO4 configuration
o36
This parameter is to configure 4
Lig=light
ALA=alarm
r-- Reference
Temperature setpoint
r00
This parameter defines the desired cabinet temperature at which compressor cuts out.
The set value can be locked or limited to a range with the settings in "r02" and "r03".
Differential
r01
This defines the difference between the cut-out and the cut-in of compressor relay.
Compressor relay will cut-in when the cabinet temperature reaches the set point+differetial.
In case of heating application, heater will cut-in when the temperature reaches the set point-differential.
Minimum set point limitation
r02
The minimum allowable setpoint value can be configured here to avoid setting too low values by
accident/mistake.
Maximum set point limitation
r03
The maximum allowable setpoint value can be configured here to avoid setting too high values by
accident/mistake.
Display offset
r04
Correction value in display temperature. If the temperature at the products and the temperature received by
the controller are not identical, an offset adjustment of the display temperature can be carried out under this
menu code.
Display temperature unit
r05
Set here if the controller is to show temperature values in °C or in °F. Switching from one to the other will cause
all temperature settings to be automatically updated to respective unit.
Calibration of Sair
r09
Offset for air temperature calibration.
Compensation possibility due to long sensor cable.
Main switch
r12
With this setting refrigeration can be started, stopped or a manual override of the outputs can be allowed.
Stopped refrigeration will give a "OFF" signal on the display.
-1=service (manual control of outputs allowed)
0=OFF
1=ON
Night setback value
r13
The thermostat's reference will be the setpoint plus this value when the controller changes over to night
operation. (Select a negative value if there is to be cold accumulation).
Activation can take place via digital input.
Thermostat reference displacement offset temperature
r40
The thermostat reference and the alarm values are shifted the following number of degrees when the
reference displacement is activated. Activation can take place via digital input.
