75NIBE F1330
Miscellaneous
Actions with operating disturbances
Low room temperature
Cause: Compressor and electric element do not heat up.
Action: Check and replace the any blown circuit and main
fuses.
Cause: The compressor does not start because of a too
low value set on the heating curve.
Action: Check and possibly increase the Heating curve off-
set (knob on the front panel) or Curve slope (see
section Room temperature.
Cause: The compressor is not running due to tripped in-
ternal overheating protection.
Action: Automatic resetting after cooling for a few hours.
Cause: Possible earth circuit-breaker tripped.
Action: Reset the earth circuit-breaker, if the earth circuit-
breaker trips repeatedly, call an electrician.
High room temperature
Cause: Incorrect setting of Curve slope and/or Offset
heating curve.
Action: Adjust the setting. Also see section Room temper-
ature.
Low hot water temperature or no hot water
Cause: Large amount of hot water drawn off.
Action: Wait until the water heater reheats.
Cause: Compressor and/or immersion heater does not
heat up.
Action: Check and replace the any blown circuit and main
fuses.
Cause: Too low start temperature on the CPU-unit (34).
Action: Adjust the hot water setting, see the section
Description of functions - Basic functions > Hot
water production.
Cause: Possible earth circuit-breaker tripped.
Action: Reset the earth-fault breaker. If the earth-fault
breaker trips repeatedly - call an electrician.
Actions with operating disturbances
In the event of malfunction or operating disturbances first
check the points below:
As F1330 can be connected to a large
number of external units even these should
be checked.
NOTE!
Standby mode
When the switch (8) is turned to the ” ” position, the
outputs for the external heating medium pumps (VBP3 and
VBP4), internal heating medium pump (VBP-A) and the
additional heat outputs (ETS-3/OP) and, when Expansion
card 11 is connected, additional heat output ETS-6 are
activated.
All control from the heat pump ceases, which means that
when the oil boiler is connected, the shunt (SV-P) must be
controlled manually.
When connecting an external electrical additional heater,
a thermostat must be connected to the control circuit. This
thermostat must be set to approximately 10 °C above the
maximal flow temperature (menu 2.4) to not have an ef-
fect in normal operation. However, in standby mode the
thermostat’s cut-out value can be lowered if necessary.
Note that hot water is not produced in standby mode.
