Introduction
Application
Complete refrigeration appliance control with great exibility to
adapt to all types of refrigeration appliances and cold storage
rooms.
Advantages
• Energy optimisation of the whole refrigeration appliance
• One controller for several dierent refrigeration appliances
• Integrated display at the front of the controller
• Quick set-up with predened settings
• 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 ow before the
evaporator (S3) or after the evaporator (S4) respectively. A setting
for thermostat, alarm thermostat and display reading determines
the inuence the two sensor values should have for each indi-
vidual 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 outlet to the electronic injection valve of the
type AKV, the controller has 5 relay outputs which are dened by
the use selected – the individual usage options are described in
detail on page 12.
Functions
• Day/night thermostat with ON/OFF or modulating principle
• Product sensor S6 with separate alarm limits
• Switch between thermostat settings via digital input
• Adaptive control of superheat
• Adaptive defrosting based on evaporator performance
• Start of defrost via schedule, digital input or network
• Natural, electric or hot gas defrost
• Stop of defrost on time and/or temperature
• Coordination of defrosting among several controls
• Pulsing of fans when thermostat is satised
• Case cleaning function for documentation of HACCP procedure
• Rail heat control via day/night load or dew point
• Door function
• Control of two compressors
• Control of night blinds
• Light control
• Heat thermostat
• Factory calibration that will guarantee a better measuring accu-
racy than stated in the standard EN 441-13 without subsequent
calibration (Pt 1000 ohm sensor)
• Integrated MODBUS communication with the option of mount-
ing a LonWorks / DANBUSS communication card
