ons
Problem Possible cause for faulty situation Counter measure
Set humidity level
not reached • Output limitation parameter setting im-
peds full power output • Check 1-1 parameter setting
•
Nominal unit output insufficient
•
Check unit technical data, air-
flow and secondary airflow
•
Phase failure or defective heater ele-
ment(s)
•
Check circuit breakers and
heater element(s)
•
Thermo switch has triggered
•
Switch off power supply. Push-
back unblocking pin on thermo
switch with needle-nose pliers
or a screwdriver
• Lengthy steam hose layout crossing cold
and drafty rooms may lead to increased
condensate formation • Change unit installation location
allowing for shorter steam hose.
Insulate steam hose
• Improper steam manifold installation may
cause condensate formation within air
duct • Check steam manifold position
within total system and installa-
tion correctness
• Control signal not properly selected or
software setting mismatch • Check control signal and „1-2“
parameter setting
• Excessive pressure in duct system
caused by e.g. water bags or partly
blocked steam pipes (max. overpressure
is 1200 Pa) • Eleminate particular cause(s)
Excessive humi-
dity
•
A steam output limitation setting that is
too high may result in poor control perfor-
mance and even condensate formation in
ducts
•
Check „1-1“ parameter setting
• Control signal not properly selected or
software setting mismatch • Check control signal and „1-2“
parameter setting
Water collects on
bottom plate • Cylinder improperly reassembled follow-
ing maintenance:
- O-ring not replaced, defective or not in
place
- Flange (tongue and groove) damaged
- Flange improperly composed
-
Mineral deposits in flange area
• Clean cylinder and assemble /
install properly
• Cylinder improperly inserted in cylinder
base • Using moistened new O-ring, in-
sert steam cylinder properly into
cylinder base
•
Water cannot drain freely when pumped
from cylinder
•
Make sure drain is unobstructed
