Page 6: Designations
6. Designations HP (High Pressure): High pressure downstream of the compressor. LP (Low Pressure): Low pressure upstream of the compressor (suction-side). HPS (High Pressure Switch): Adjustable HP value to switch off the compressor and to issue an alarm signal. Hdt (High Pressure Delay Timer): Adjustable delay for the HPS in order to avoid unstable system behaviour. -

9. Operation Pressure indicator mode: In this mode, the LP and HP pressures are displayed in the set unit. Temperature indicator mode: button is used to switch between pressure display mode and temperature display mode. The display switches to temperature display mode automatically after 20 seconds. Setting mode: Activate setting mode by pressing and holding down the button. -
