Components and function description
Here we describe the function and
specification of the most important
components. Certain components are found
only in more highly specified machines or in
particular markets. See the Troubleshooting
chapter for fault and information codes.

CU (Control Unit)
The CU (Control Unit) functions as both a
control panel and a logic component. The
control panel is equipped with knobs/buttons
for selecting programmes, Start/Stop buttons
and a display. It is an integrated part of the
CU and cannot be replaced separately. The
logic component manages functions needed
for drying programmes and diagnosis. The
CU has an internal power supply for the logic
component. In the event of a fault, the CU
can diagnose a number of components and
functions, and a total of 4 fault codes can be
displayed. To facilitate troubleshooting there
is a component testing function in which the
outputs are activated according to a special
sequence.

Power supply
Mains voltage, built-in internal voltage
converter for the logic component.

Thermistors
The thermistors are of the NTC type (Negative
Temperature Coefficient), which means their
resistance decreases as temperature increases.

Thermistor 1 is in the air duct on the front frame,
after the internal impeller. If there is an interruption
in the thermistor circuit or if it short circuits, the
drying programme stops and the display shows
“Thermistor fault”.
Purpose: Measures the temperature of the air that
has passed the load and controls the drying process
and the heating element.

Thermistor 2 is on condenser dryers located after the
condenser and on heat pump dryers located on the
evaportator pipe by the comperssor.
Purpose: Measures the temperature of the
dehumidified air, the value of which is used as a
parameter in the drying process.
