2. Liquid ejectors

Operating mode: Control of the accumulator fill level (parameter "Acc. Level Ctrl" set to YES)

The liquid ejector stages are switched on and off with the delay time (parameter "Delay FIEj.") if the refrigerant 
level exceeds or falls below the corresponding accumulator level switch. After the penultimate accumulator 
level switch has been exceeded, the remaining liquid ejector stages are switched on after the waiting time has 
elapsed (parameter "Waiting time LE ON").

Number of liquid ejectors: 3
number of accumulator sensors: n (max.4)

Operating mode: High pressure control (parameter "Acc. Level Ctrl" set to NO)

The liquid ejectors are switched together with the gas ejectors to control the high pressure. The prioritisation of 

which ejector type is switched first is based on ambient temperature (threshold 22 °C). The switching behaviour 

corresponds to the gas ejector modes described above with the number of ejectors increased by the liquid 
ejectors.
