The following settings only apply if "Defrost" was selected in point 3.
Defrost
Defrost
With this function the point can receive information about when a
defrost is in progress.
This information can be used by other points to ensure they do
not send temperature alarms during this period.
The following settings only apply if "Gas detector" was selected in
point 3.
Gas detector
Gas detector
This function monitors the concentration of refrigerant in the
room air. An alarm is generated if the set value is exceeded.
Two alarm limits can be set.
A "high" is when the critical limit is reached. This is when the alarm
is transmitted.
A slightly lower threshold will also generate an alarm, but this
alarm can be read as a "Leakage check".
This list of settings was
previously covered under
temperature. Please see the
explanation on pages 24-25.

The alarm function will be enabled if the defrost signal remains on
the input.
Scaling factor
The measurement from the gas detector is recorded as a %, i.e.
0-100.
A factor can be set here so that the display is shown in ppm.
Setting = full reading from the gas detector divided by 100.
For example, 30000ppm/100=300.
