Heat thermostat

The heat thermostat is typically used if the
temperature is to be controlled within narrower
limits, e.g. for cutting rooms, etc. The heating
thermostat can be set as a difference in relation to
the cutout limit for the refrigeration thermostat so
that simultaneous refrigeration and heating are
avoided.
Application 6
Two refrigeration sections – two defrost outputs
This application is for refrigeration appliances with
one valve, two evaporators and two refrigeration
sections. The temperature is controlled and is
always alarm monitored according to the S4
temperature.
The two S3 sensors send a signal to the display in
each section.
Application 7
Two refrigeration sections – individual alarm/
display via S3
This application is for refrigeration appliances with
one valve, one evaporator and two refrigeration
sections. The temperature is always controlled
according to the S4 temperature.
There are two S3 sensors. Alarm monitoring and
display readings take place individually via the
"S3" sensors in each refrigeration section.
There are separate alarm delays for each cooling
section.

• Rail heat
Application 9
Thermostat band-determined compressor
operation.
Runs in thermostat band 1 with sequential "two-
compressor" operation; first compressor 1, and
then compressor 2.
In thermostat band 2, compressor 2 can be de-
selected so that only compressor 1 is used.
There are separate thermostat differences and
defrost stop definitions for the two thermostat
bands.
