Code Message Information
Warning Fault Possible causes Remedy
––– E22 Max. Filling Time The Condair RS is monitoring the lling process with different levels which have
to be reached within a preset time during lling. If a certain level is not reached
within the preset time the fault message "Max. Filling Time" is triggered.
Note: the inlet valve remains open. .
Water feed blocked, shut-off valve in
the water supply line closed, lter valve
closed or blocked).
Water pressure too low.
Check water feed (lter, pipes, etc.),
check/open shut-off valve, Check water
pressure.
Inlet valve blocked or defective. Check strainer inside the inlet valve,
clean if necessary. Replace valve.
Excessive back pressure in the steam
line (duct pressure too high, steam line
too long or kinked), causing water loss
via lling cup.
Check duct pressure, inspect steam
installation. If applicable install pressure
compensation kit (available as option).
water system leaky. Check/seal water system.
––– E26 ** Contactor Jammed There is voltage on the power board, even though the main contactor is not activated!
Main contactor jammed. Check the main contactor and replace
it if necessary.
W28 E28 Small maintenance The maintenance interval for the "Small maintenance" has elapsed. If the "Small
maintenance" is not performed and the maintenance message is not reset within
one week after the maintenance message has been triggered a fault message
is triggered!
Note: The Condair RS remains operable. The maintenance message is shown
until the maintenance counter is reset.
"Small maintenance" due. Perform "Small maintenance" and reset
maintenance counter.
W29 E29 Extended mainte-
nance
The maintenance interval for the "Extended maintenance" has elapsed. If the
"Extended maintenance" is not performed and the maintenance message is not
reset within one week after the maintenance message has been triggered a fault
message is triggered!
Note: The Condair RS remains operable. The maintenance message is shown
until the maintenance counter is reset.
"Extended maintenance" due. Perform "Extended maintenance" and
reset maintenance counter.
––– E32 Demand Snsr Demand signal invalid, humidication is stopped!
Humidity sensor or external controller
not or not correctly connected.
Check/correctly connect humidity sen-
sor/external controller.
Sensor/controller wrong congured (e.g.
mA signal instead of V signal set).
Correctly congure sensor/controller via
the conguration menu.
Sensor/controller defective. Replace sensor/controller.
––– E33 Limit.Snsr Signal of the external limiter controller invalid, humidication is stopped!
Limiter controller not or not correctly
connected.
Check/correctly connect limiter con-
troller.
Limiter controller wrong congured (e.g.
mA signal instead of V signal set).
Correctly congure limiter controller via
the conguration menu.
Limiter controller defective. Replace limiter controller.
W34 E34 Max. Drain Time The level in the steam cylinder has not dropped to the preset level within
the preset time. The Condair RS carries out a level test. This procedure is
repeated three times if maximum drain time is exceeded again, then a fault
message is triggered and humidication is stopped!
Drain pump not or not correctly con-
nected.
Check/correctly connect drain pump.
Drain hose inside the unit kinked or
blocked.
Check/Cclean drain hose inside the unit,
replace if necessary.
water drain obstructed (external drain
line or funnel blocked.
Clean external drain line and funnel.
Hoses to level unit blocked. Clean or replace hoses.
