At this oil temperature, measured in the oil manifold, the solenoid valve in the liquid line closes to the
injection valve (only mounted on compressors cooled by liquid injection).
F2:
LIQUID INJECTION ON
At this oil temperature the solenoid valve opens for supply of liquid refrigerant for the injection valve
(only mounted on compressors cooled by liquid injection).

SETUP
Here, if brine temperature regulation is to be used, the brine temperature in degrees Celsius for which
the compressor is to adapt capacity must be given. Can only be used with the operating forms
"MASTER" and
"REMOTE WITH OWN SETPOINT" (= REMOT5)
F4: T-BRINE
START
In operation where the compressor regulates in accordance with the setpoint for brine temperature, a
start signal is given to the compressor when the temperature of the brine is the number of degrees given
at this setpoint higher than the brine setpoint value (setp. E/F5).
F3: T-BRINE
STOP
With brine regulation, the compressor stops when the brine temperature at this setpoint is the number of
degrees given at this setpoint lower than the brine setpoint value (setp. E/F5).
F2:
BRINE REGULATION YES/NO
If the form of operation is "MASTER" or "REMOT5" and resistance input R IN 4 is OFF, and if the
answer for this setpoint is given as YES, regulation will be performed in accordance with the brine
temperature.
The brine temperature is measured on analog input 5 (A IN 5) where -50 to +50°C corresponds to 4-20
mA.
