    It is part of the safety chain. The PZH is installed on the refrigerant collector for the chiller types cBoxX 40 – cBoxX 180 (see Figure 10: Position of the high pressure limiter (PZH)).

  • Page 32: High-Pressure Monitoring

    4.4.2. High-pressure monitoring If the high pressure in the refrigeration circuit of your machine increases to a maximum value, the compressors are switched off via the high-pressure limiter (see Chapter 4.4.1 High-pressure limiter). A manual reset is required. The high-pressure monitoring on the other hand reduces the compressor output before the PZH's switch-off value is reached.
