Single-phase axial or centrifugal fans operation with speed control

Speed selection is carried out in both the cooling as well as the heating cycles.

- In “pump absent” mode, the flow switch alarm is deacti- - To see pump operating hours, see DIRECT cC parameter. vated.

- The water pump will start 20 seconds before compressor (c7) starts.

- When the compressor turns off, the pump will continue op- erating for 20 minutes more (c8).
