5. Anti-frost protection during winter
This protection can only be activated if the heat pump is in STAND-BY mode.
5.1 First anti-frost protection
If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and
when the water temperature lies between 2 and 4 °C and the air temperature is lower than
0 °C, the filter pump will be automatically turned on to prevent the water from freezing in the
piping. This protection is deactivated when the temperature rises again.
5.2 Second anti-frost protection
If the water temperature drops even more, that is, below 2 °C (during long frost periods), the heat
pump will also start running to heat the water until its temperature approximates 3 °C. When this
temperature is reached, the heat pump will stop, but anti-frost protection will remain active until
conditions change.
6. 3-fase protection
If the phases are connected in the wrong order due to electrical miswiring, this protection
will interrupt
the power supply to prevent mechanical deformation. There will be an EE 4 error code on
the display.
