Integral capacity The illustration below shows the integral capacity in function of the compressor running time.
Mode 0 Intelligent control mode
When the DIP switches are in mode 0, “intelligent freeze-up prevention control” determines the
freeze-up activation. The outdoor unit can determine the freeze-up activation.
Mode 1 Disabled intelligent control mode
The table below contains the freeze-up conditions, these are the same as for the Sky Air G- and
K-series.
Mode 2 Added countermeasure to avoid ice/water blow out during freeze-up cycle.
Mode 2 enables the possibility to start a freeze-up activation decision by the outdoor unit, but with
more severe conditions than in mode 0.
Mode 3 Mode 3 is used in case mode 2 is insufficient as countermeasure.
