VZH Map Control (only for mother unit):
The brick controls the saturated evaporating and condensing temperature values and
check that the VZH compressor working zone is inside the compressor envelope. Based on the working zone, a new compressor
demand is generated with the target to keep the compressor working in a safety zone. A warning or alarm message is generated
when needed.

VZH Oil Manager (only for mother unit):
The brick controls the oil level in VZH compressors and takes the appropriate actions to
ensure the safe operation of the compressors. It tries first to push the oil trapped in the system back to compressor, increasing the
compressor speed for short periods (boost procedure) and finally it generates an alarm when necessary.
Figure 66. VZH Oil Manager
The compressor has an oil level switch, and the VZH oil manager is configured based on oil lever sensor, it means that only when the
switch detected low level, the oil boost sequence will start.
