If using two control circuits, the control circuit with the higher modulation can be
selected to affect the power component of the device.
This function can be used for refrigeration systems with combined refrigerant circuit
and floating brine pressure control circuits, for example.
Example:
•
Control circuit 1 is used for the refrigerant circuit. A pressure sensor is connected to
determine the actual value. The setpoint and control range are set in bar.
•
Control circuit 2 is used for the brine pressurised circuit. A temperature sensor is
connected to determine the actual value. The setpoint and control range are set in
C° / K.
•
Depending on which control circuit produces the higher modulation (depending on
the measured and set values), the pressure control or temperature control is used
as a specification for the power component.
Selection amplifier = OFF (factory setting)
No comparison of the two control circuits.
Selection amplifier = ON
