Warnings
Plain text message
FILTER WECHSELN (change filter)
The differential pressure switches switch
via the air filters when the max.
permissible pressure drop is exceeded.
HEIZUNG ZU KALT (heating too cold)
After 30 min under full load the RHZ
temperature must reach a value of at
least 60 °C, in controlled operation the
value is not prompted.
WENIG REGEN.-LUFT (little amount of
regeneration air)
Differential pressure switch monitors the
pressure loss via regeneration heating
and regeneration sector at the rotor and
releases the heating when a minimum
value is reached.
Faults
Plain text message
VENTI. PROZ.LUFT (fan process air)
Fault message from EC motor
VENTI. REGEN.LUFT (fan regeneration
air)
Fault message from EC motor
ROTOR-ANTRIEB (rotor drive)
Rotor rotation control/inductive proximity
switch is evaluated
THERMOSTATE (thermostats)
Safety temperature limiters (STB) are
prompted.
If an additional heating is used, the STB
is prompted, too.
If the fault cannot be rectified, please contact one of our
subsidiaries or our headquarters.
