Parameter Description
11
- In “pump absent” mode, the flow switch alarm is deacti-
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).
- To see pump operating hours, see DIRECT cC parameter.
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.
