Introduction
Application
Complete refrigeration appliance control for SemiPlugin
refrigeration appliances.
- Where condensation heat is removed using brine
- Flammable refrigerants supported
- The total amount of refrigerant can be distributed across more
circuits
- Variable speed compressor control
Advantages
• Energy optimisation of the whole refrigeration appliance
• One controller for several different refrigeration appliances
• Integrated display at the front of the controller
• Built-in data communication
• Built-in clock function with power reserve
Principle
The temperature in the appliance is registered by one or two
temperature sensors which are located in the air flow before the
evaporator (S3) or after the evaporator (S4) respectively. A setting
for thermostat, alarm thermostat and display reading determines
the influence the two sensor values should have for each
individual function.
In addition product sensor S6, which can be optionally placed in
the appliance, can be used to register the temperature near the
required product in a certain place within the appliance.
The temperature of the evaporator is registered with the S5 sensor
which can be used as a defrosting sensor.
In addition to the output for the compressors, the controller has 5
relay outputs for dedicated applications.
Functions
• Day/night thermostat
• Product sensor S6 with separate alarm limits
• Switch between thermostat settings via digital input
• Start of defrost via schedule, digital input or network
• Natural or electric defrost
• Stop of defrost on time and/or temperature
• Coordination of defrost across several controls
• Pulsing of fans when thermostat is satisfied
• Case cleaning function for documentation of HACCP procedure
• Rail heat control via day/night load or dew point
• Door function
• Control of two compressors or one variable speed compressor
• Control of night blinds and light
• Factory calibration that will guarantee a better measuring
accuracy than stated in the standard EN ISO 23953-2 without
subsequent calibration (Pt 1000 ohm sensor)
• Integrated MODBUS communication with the option of
mounting a LonWorks or DANBUSS
