▶
Inform your competent person so that
he can top up the brine fluid.
F.723 Building circuit: Pressure too low
If the filling pressure falls below the min-
imum pressure, the heat pump will be
switched off automatically.
–
Min. heating circuit pressure:
≥
0.05 MPa (
≥
0.50 bar)
–
Min. heating circuit operating pressure:
≥
0.07 MPa (
≥
0.70 bar)
▶
Inform your competent person so that
he can top up the heating water.
F.1120 Heating rod: Phase failure
The product has an internal circuit breaker
which switches off the heat pump in the
event of short circuits or the failure of
one (product with 230 V power supply) or
several (product with 400 V power supply)
current-carrying phases. This may be
caused by a defect in the internal auxiliary
electric heater, for example.
If the auxiliary electric heater is defective,
the Anti-legionella function is not guaran-
teed.
▶
Inform your competent person so that
they can rectify the fault and reset the
internal circuit breaker.
