Appliance faults Remedy
Flow noises ▶ Set the pump rate or pump parameter field correctly and match it to the maximum
output.
▶ Vent the hybrid manager ( chapter 6.2.11, page 38).
Heat-up takes too long ▶ Set the pump rate or pump parameter field correctly and match it to the maximum
output.

FAQ Steps to be taken
The external unit does not work at all. External unit cannot be returned into
operation after an idle period.
Wait at least 3 minutes before trying to restart.
The external unit is protected by an automatic safety device. For 3
minutes after the compressor stops it cannot be restarted.
The external unit develops too much
noise.
Noise like escaping gas can be heard. This is not a fault. This noise can be heard when the refrigerant enters
the system.
A cracking sound can be heard. This is not a fault. This noise can be heard when the components in
the external unit contract or expand as a result of temperature
changes.
A humming sound can be heard. This is not a fault. This noise can be heard when the external unit
starts.
A ticking noise can be heard. This is not a fault. This noise can be heard when the fan regulates the
air volume to achieve the optimum operating mode.
Noise like water can be heard. This is not a fault. This noise can be heard when the refrigerant flows
into the external unit.
Water or humidity escapes from the external unit. It is quite normal that condensate forms at certain parts. The
condensate should be caught and drained off by a condensate drain
or condensate pan.
