Applications
Here is an overview of the controller’s usage options.
A setting will congure input and outputs so that the controller’s
operation interface is directed at the selected application.
Application 1-5
These uses are applied to standard appliances or cold storage
rooms with one valve, one evaporator and one refrigeration
section.
The sensors are used according to standard principles.
The output functions change depending on the selected
application.
Application 6
This use is for refrigeration appliances with one valve, two
evaporators and two refrigeration sections.
Here the temperature and alarm monitoring are always controlled
using the S4 sensor.
The two S3 temperatures are used to display the reading for each
cooling section.
There are two defrost sensors – one for each evaporator.
Application 7
This use is for refrigeration appliances with one valve, one
evaporator and two refrigeration sections.
Here temperature is always controlled using the S4 temperature.
The two S3 temperatures are used for alarm monitoring and
display readings for each refrigeration section. There are separate
alarm delays. There are two product sensors S6, one for each
cooling section.
General data
• Supply = 230 V a.c.
• Sensor inputs = 6 no.
• Compressor / solenoid valve output = 1 no.
• Number of relay outputs = 5 no.
• Pt 1000 ohm sensors on all outputs (all air sensors can however
be changed to PTC 1000 ohm)
• Two versions with dierent sensor connections:
- Screw terminals
- AMP plug
Digital input
There are three digital inputs available with many usage options
for all settings. The two inputs are connection inputs and the third
is a 230 V input.
Extra modules
A module can be mounted in the control. It can be for one of the
following functions:
Data communication with MOD bus
Data communication with LON RS 485
Battery module with extra power reserve.
