Possible Condi-
tion
Probable cause for fault situation Resolution
set humidity level
has not been
reached
• The unit’s steam generation output limita-
tion is impeding full output
• Check steam generation output
limitation parameter “P1”.
• Nominal unit output is not sufficient. • Check output data, air flow, also
check secondary air flow
• Phase or heater element failure. • Check breakers and heater ele-
ments.
XX • Thermo sensor has been activated.
(only for Humidifer type HeaterLine)
• Disconnect power supply. Push
down on the release pin with
bent needle-nose pliers.
• Long steam hose length in cold and drafty
rooms can lead to increased formation of
condensate.
• Install the unit in another loca-
tion to reduce the required hose
length.
• Incorrect installation of the steam mani-
fold can produce condensate build-up in
the air duct.
• Check placement in the system
and installation.
• Incorrect control signal adjustment leads
to faulty and possibly excessive ouput.
• Check control signal and pa-
rameter “E3”.
• Water quality requires water concentra-
tion for full output
XX
Too much humid-
ity
• Too high a steam generation output limi-
tation can cause poor control and even
produce formation of condensate in
ducts.
• Check steam generation output
limitation.
• Incorrect control signal adjustment pro-
duces excessive output.
• Check control signal and pa-
rameter “E3”.
XX
Water is collect-
ing on the base
plate
• Cylinder improperly assembled after
maintenance:
-O-Ring has been damaged, has not
been replaced, or has not been inserted
- Flange ( slot / spring) is damaged
- Flange has not been sealed properly
- Mineral deposits in the flange.
• Clean cylinder and install prop-
erly.
• The cylinder is incorrectly placed on the
base.
• Lay a moistened new o-ring in
the base and then insert the cyl-
inder.
• The water cannot drain away during
flushing.
• Make sure drain is unobstruct-
ed.
