7. RESIDUAL HUMIDITY CONTROL (Optional)
Humidity control is a system, which automatically adjusts the length of the drying cycle to
the of fabric and load, thus guaranteeing optimum levels of operation in terms of time and energy
consumption.
The humidity probe monitors the relative humidity value and when it reaches the
setting defined by the user, the microprocessor stops the drying cycle and switches to Cool-
down, to gradually cool the clothes.
The preset microprocessor programmes have relative humidity values set as default,
see table in chapter 6.
To change the relative humidity values indicated in the preset programmes, press
"SELECT" and increase or decrease using the keypad arrows. If you want to change the preset
values in a programme, edit the humidity value in the required programme as indicated in
chapter 6.
The relative humidity levels at which the clothes are considered to be dry range between
15 – 35% RH depending on various parameters. We recommend that the user establishes the
most appropriate level for their required use.
7.1. Intelligent dry
Humidity control includes the standard intelligent dry system that consists of looking for
the drum rotation speed to make the dryer extract at each moment of the drying cycle the
maximum amount of water achieving in this way the drying time and therefore achieving a
better performance.
When the humidity control option is selected, the Intel Dry option is automatically
activated.
When Intel Dry is active, the time between each rotation reversal (rotation cycle) is fixed
and cannot be changed. This value corresponds to the minimum time needed to carry out the
speed adaptation process which takes 75 seconds.
The speed adaptation process consists of an exploration phase and a positioning phase.
During the exploration phase, the microprocessor will try 7 different speeds that will go
from lower to higher. For each speed the microprocessor will memorise the humidity detected in
the air extracted.
Immediately after, the positioning phase starts where the microprocessor has memorised
the speed where the humidity value has been the highest. The dryer's drum will rotate at that
speed until the next speed adaptation process starts.
The speed adaptation processes will be repeated in the following way during the
drying cycle:
No speed adaptation process will take place during the first rotation cycle, but it will take place
during the second cycle. During the third and fourth no, during the fifth yes, during the sixth
and seventh no, during the eighth yes, and so on.
