MODE A
Every unit manages its own compressors according to the
setpoint.
Every unit optimizes its refrigeration circuits.
Pumps always active, even with compressor stoped.
P0343 = 0
P0344 > 0 °C
setpoint1 > setpoint2 > setpoint3
or
setpoint1 < setpoint2 < setpoint3
MODE B
The master manages the single cooling.
The master optimizes individual refrigerant circuits.
Pumps always active, even with compressor stoped.
P0343 = 1
P0344 = 0 °C
setpoint1 = setpoint2 = setpoint3
plus: optimal H2O temperature control
MODE C
The master manages the single cooling.
The master optimizes individual refrigerant circuits.
Active pumps only with active compressors.
P0343 = 2
P0344 = 0 °C
setpoint1 = setpoint2 = setpoint3
plus: minimum pumps consumption need balanced system (t1 = t2 = t3)
