HS.95: Capacity control (CR) and start
unloading (SU)
The HS.95 compressors are equipped with an infinite
capacity control (slide control). The compressor module
controls the solenoid valves. Interconnected electronic
controls allow operators to selectively activate certain
additional part-load points as needed (depending on
the application limits). For detailed explanations of ca-
pacity control activation, see Technical Information
ST-150.
Information
For start unloading, the compressor module
sets the capacity slider to the minimum dis-
placement. A period of approx. 5 min must be
provided for this in the system controller.
