Medium pressure maintenance by opening the HP valve

If no pressure maintenance valve is available, the HP valve can be opened when medium pressure is dropping.
The HP valve can be opened with the minimum opening degree

Min contr val.

(menu 3-2-2-2

) when the high

pressure is greater than 40 bar and the medium pressure has fallen to 1.0 bar below the MP setpoint. If the
medium pressure falls lower than 1.5 bar below the MP setpoint, the HP valve can be opened continuously for
further dropping medium pressure. Using this function, the HP valve can be opened up to 30% of the maximum
opening degree. However, the opening degree can be higher due to the HP regulation. This function is
deactivated when ECO operation is running.

5.8 ECO operation

Introduction

A configuration of a refrigeration pack system that controls the "ECO compressors" for regulation of the medium
pressure is designated as ECO operation. The ECO compressors can be controlled in two ways:

• Variant A:

Control by a VS 3015 C

Control by a VS 3015 C and a separate pack controller
