Nibe FIGHTER 310P, Installation And Maintenance Instruction, Page: 23 / 36

When the switch is set to “ ” the compressor and
electronic controls of the heat pump are off.
The fan is operational and the immersion heater is
controlled by a separate thermostat.
The numerical display is off. The automatic heating
control system is not operational, so manual shunt
operation is required. This is done by turning the
adjuster screw to manual mode and then turning the
shunt lever to the required position.
The display can remain unlit when returning to normal
mode. This is due to the boiler temperature being
above the heat pump's normal working area. The dis-
play comes on when the boiler temperature drops
once again to normal.
