S5 Start/Stop
Start a program by pressing the button and stop by pressing it for 3 seconds.
S6 Time delayed start
The start of a program can be delayed for 1-12 hours. Push the button so many
times that you want the start to be delayed. By thirteenth press, the delay will be
zero. D3 and D4 indicate the chosen amount of hours.
Test program
Through pressing S1.1 5 times and S1.2 for 5 times, you get into a test program.
A press on
S1.2 will lit

S4 The buzzer is activated
”
S1.4 starts the motor,heater, high effect, heater low effect, and
outlet pump .
There will be a heating up till 50° C . After that the heater, low effect, is turned off.
The heating-up continues to 60°C and then all components are shut off.
During the heating-up the moisture in the machine is indicated by D1 and D2
(normally 3-13). D3 and D4 indicate the temperature.
Fault signals:
The following codes are indicated by D3 and D4.
F1
Overfilling in the condensate water container
F2
Maximal drying time, 3 hours
F3
Thermistor fault
F4
Fluff in the fluff filter or in the condenser (indicated after end of program)
F5
Fault in the moisture sensor
Reasons for faults
Open-circuited or short-circuited thermistor
This will interrupt the program and produce a flashing F3 on the display. An open circuit
can be caused by a broken connection or a faulty thermistor. The resistance of a
helthy thermistor is between 60 kohm and 40 kohm at 20-30°C.
Thermistor not in thermal contact with the fan casing
The heating element will be energised as long as the thermistor does not sense the air
temperature called for by the program, resulting in excessive air temperature.
