If the current sensors are connected, the heat pump
monitors the phase currents and allocates the electrical
steps automatically to the least loaded phase.
Emergency mode
When the heat pump is set to emergency mode (SF1 is
set to ) only the most necessary functions are activated.
The compressor is off and heating is managed by the
■
immersion heater.
Hot water is not produced.
■
The load monitor is not connected.
