Adjustment in hot mode
The regulators can work in hot (heat pump) mode if parameter CF13 is configured correctly.
The diagram below represents the proportional adjustment in hot mode. The integral component is not represented (Rl04 = 0).
For ON-OFF adjustment, the cut-off delta must be set to 0 and there will be only one adjustment step, as shown on the diagram below.
7.3.3
Oil refresh
If the compressor is running at a frequency lower that the CP09 parameter for a period longer than the CP10 parameter, it is activated
at the maximum frequency. The compressor will remain at the maximum power until it reaches the set-point.
