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.
႑
The compressor is off and heating is managed by the
immersion heater.
႑
Hot water is not produced.
႑
The load monitor is not connected.
NOTE
Switch (SF1) must not be moved to " "or" "
until F1245 has been filled with water. Other-
wise the temperature limiter, thermostat, com-
pressor and the immersion heater can be dam-
aged.
Power in emergency mode
The immersion heater’s output in emergency mode is set
with the dipswitch (S2) on the immersion heater circuit
board (AA1) according to the table below. Factory setting
is 6 kW.
