Nibe F1145 series User Manual

The table displays the total phase current for the immer-
sion heater at start up. If an immersion heater has
already been started and is not used for its full capacity
the values in the table can be changed because the
control initially uses this immersion heater.
Switching to maximum electrical output
If more than the maximum output (7 kW) for the immer-
sion heater connected on delivery is needed, the heat
pump can be switched to maximum 9 kW.
Move the white cable from terminal block X7:23 to ter-
minal block X3:13 (the seal on the terminal block must
be broken) on the immersion heater card (AA1).

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 activ-
ated.
• The compressor is off and heating is managed by the
immersion heater.
• Hot water is not produced.
• The load monitor is not connected.
NOTE
The switch (SF1) must not be moved to "" or
" " until F1145 has been filled with water.
Components in the product can be damaged.
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.
