•Each step always consists of a Dry sequence and a Cooldown
sequence.
•You will notice that each step has default settings. This feature is very helpful as most of the newly created programs
will not require changes to be made to the suggested values.
Programming the Dryer sequence :
•First set the target temperature.
•Then set the Dry time or Humidity (only applies to machines
fitted with a humidity sensor).
Programming the Cooldown sequence :
•After programming the Dry sequence, next program the Cooldown sequence.
•Set the parameter to stop the Cooldown sequence : Time or
Temperature
•As you will notice it’s also possible to skip a sequence between two other sequences by programming a time value =
0. )
The Anti-Wrinkle sequence :
•To avoid Wrinkling, its recommended that the linen is reversed each 2 to 10 minutes once the drying cycle has finished and the machine is not unloaded. A beep signal warns the
operator that the cycle has been finished.

At the drying process with humidity control, the air humidity is
measured by an absolute air humidity sensor. The graph shows
the absolute air humidity in function of time. When a drying cycle is started, the air humidity will go up quickly as the heating
system starts up, then the air humidity will decrease bit by bit.
The dryer computer humidity sensor measures this value and calculates the corresponding residual humidity of the linen. The residual humidity is the remaining amount of water in wet linen
compared with it's dry equivalent. When the linen is taken out a
washing machine:
•A high extraction speed results in about 50 % residual humidity
•A low extraction speed results in about 70 % residual humidity
At the drying cycle (humidity control) the display shows :
•H - - : The residual humidity is above 30 % (the linen is wet)
30 Part No. D1621ENR3
Page 31
•H XX : The residual humidity value is below 30% (the linen
gets dry)
Above 30% residual humdity, the linen is so wet that there is no
accurate measurement. For this reason there is not shown a value
on the display, just two dashes. It can take 10 to 40 minutes, depending the amount of load and how wet the linen is, before the
Residual Humidity Value is shown on the display.
The default programmed value for residual humidity of linen is
5%.
IMPORTANT: While the dryer is running, do not open
and close the door, it disturbs the humidity control
measurement.
WARNING
CERTAIN FABRICS CAN GET DAMAGED WHEN
DRYED UNTIL A RESIDUAL HUMIDITY OF 0%.
(BONE DRY). CERTAIN FABRICS GET ELECTROSTATIC CHARGED FOR A RESIDUAL HUMIDITY BELOW 5% (WHICH SHOULD BE AVOIDED).

C178
Troubleshooting problems with Humidity Control:
Operation with a small load of laundry
The humidity control system is not designed for operation without any load, or with a very small load. It is advisable to set the
maximum dry time after which the drying operation will be terminated
•(Refer to chapter Programming the drying part).
Check dust filter cap
When humidity control does not work, check if the dust filter cap
is missing. The dust filter cap is a white cover that must not be
removed from the sensor device. The dust filter cap allows air to
pass.
If a memory error occurs, then something is wrong with the EEPROM.
Try to reload the Programs. Check for source of electrical
“noise“.
Failure 170-199: Sofware Errors
Software errors must never occur, if a software error message occurs, inform the manufacturer.
Humidity Control - Troubleshooting
The analogue value humidity sensor can be watched while drying
the linen. This can be helpful for diagnostic purposes.
While dryer is running, programming switch in Program mode,
press Status Button and Humidity Button and the analogue value
humidity sensor is shown.
Check door lock system
When the dryer door is not completely closed, air from the room
is sucked in the dryer. This causes a wrong air humidity measurement. Make sure the dryer can only run when the door is in the
closed (locked) position. (When door is still 10 mm open, it
should not be possible to start a dryer program.)
Check heating and airflow
The air humidity measurement can only function when there is
sufficient water evaporation from the linen. Evaporation can only
happen when the, air and indirectly the linen is sufficiently heated. If the dryer has to run with reduced heating power, the airflow
must be sufficiently reduced so there is still evaporation.
Example:
•There is in sufficient Electrical Current available at the building.
•The dryer works with only 50% of it's electrical heating power.
•The airflow must be sufficiently reduced so there is still
enough evaporation inside the dryer to allow optimal humidity control.
At a normal drying process, the outlet air temperature reaches the
programmed target value when the linen gets dry. For a correct
drying process: when humidity control stops the dryer, the dryer
must have reached, before the end of the drying cycle, the programmed target temperature value. If this is not the case, probably there will not have occured sufficient evaporation at the drying process because of reduced heating power. And the air humidity measurement will not have been accurate to allow optimal
humidity control.
Linen must be sorted
A mixture of linen in the dryer can not result in an equal drying
result. It is a good practice that the same kind of linen is sorted
and dryed together, (Coton, Synthetic). In case of Humidity Control, a mixture of all kinds of linen will not give a good overall
drying result.
Thin - Thick Fabrics
Thick fabrics, like jeans or trousers, need a long drying time.
Dryer program will stop when fabrics are mostly dry, but inside
pockets will still feel damp. In case of thin fabrics, where the linen is sewed together there may be damp spots. Humidity Control
stops the dryer when the linen is dry, based on the measured air
humidity.
Troubleshooting
Correct Load in Drum
Some fabrics need more space in dryer than others. It is important
to choose the right size of dryer to obtain a good airflow.
•If there is more linen in the drum, the airflow will be restricted and the linen will not be dried evenly.
PROFESSIONAL REPAIRS IN ELECTRO INSTALLATION CAN BE CARRIED OUT ONLY BY SERVICE ORGANIZATION WITH PERMISSION GIVEN BY PRODUCER / SUPPLIER.
