Introduction
Application
• The controller is used for temperature control refrigeration
appliances in supermarkets
• With many predefined applications one unit will offer you many
options. Flexibility has been planned both for new installations
and for service in the refrigeration trade
Principle
The controller contains a temperature control where the signal
can be received from one or two temperature sensors.
The thermostat sensors are either placed in the cold air flow after
the evaporator, in the warm air flow just before the evaporator,
or both. A setting will determine how great an influence the two
signals are to have on the control.
A measurement of the defrost temperature can be obtained
directly through the use of an S5 sensor or indirectly through
the use of the S4 measurement. Four relays will cut the required
functions in and out – the application determines which. The
options are the following:
• Refrigeration (compressor or relay)
• Fan
• Defrost
• Rail heat
• Alarm
• Light
• Fans for hotgas defrost
• Refrigeration 2 (compressor 2 or relay 2)
The different applications are described on page 6.
Advantages
• Many applications in the same unit
• The controller has integrated refrigeration-technical functions,
so that it can replace a whole collection of thermostats and
timers
• Buttons and seal imbedded in the front
• Can control two compressors
• Easy to remount data communication
• Quick setup
• Two temperature references
• Digital inputs for various functions
• Clock function with super cap backup
• HACCP (Hazard Analysis and Critical Control Points)
- Temperature monitoring and registration of period with too
high temperature (see also page 19)
- Factory calibration that will guarantee a better measuring
accuracy than stated in the standard EN 441-13 without
subsequent calibration (Pt 1000 ohm sensor)
