Fault
A serious fault has occurred. The heat pump and all outputs are switched off too.
Defrost
In an air / water heat pump, the evaporator, on which ice can form, is defrosted. This function may have
been triggered by the button "manual defrost" or by the automatic defrost process.
Cooling mode
This condition indicates that the heat pump is cooling, i.e. the process is reversed and the system is
