during start-up, while the hysteres line flashes. The
next screen appears to set the hysteresis for
temperature :
Hysteres

3. Press repeatedly until the desired hysteresis value
(1°C – 5 °C) appears on the screen and remove the
precision screwdriver from the hole. After a few
seconds, the setting is automatically saved and the
next screen appears to set the hysteresis for relative
humidity:'

4. Press repeatedly until the desired hysteresis value
(1% – 5%) appears on the screen and remove the
precision screwdriver from the hole.
After a few seconds, the setting is automatically
saved and you will enter the screen Time Delay
(section 4.5).

4.5 Setting the time delay

With time delay you set how long the controller has to
wait before switching between day and night mode. To
do this, follow the steps in section 4.4 and the following
screen is displayed:
Delay
2M
Press repeatedly until the desired time delay (0, 2, 5, 10,
20 or 30 minutes) appears on the screen and remove the
precision screwdriver from the hole. After a few seconds,
the setting is automatically saved and the main screen
appears.

4.6 Idle speed

If the measured temperature in the room is equal to the
set temperature, the fan runs at idle speed. This fan
speed lies in the exact middle of the set minimum fan
speed and the maximum fan speed (100%). If the
temperature deviates within the range of the set
hysteresis, the fan speed will adjust in proportion to the
idle speed.

Example
The set minimum fan speed is 40%.
The maximum fan speed is 100%.
The set temperature is 27 °C.
The set hysteresis is 2 °C.
In this case, the idle speed is 70% (100% - 40% = 60%
range, divided by 2 gives the distance to the exact
middle: 30%). The idle speed lies in the exact middle of
40% and 100%, therefore at 70% (100% minus 30%).
If the measured temperature is equal to the set
temperature of 27 °C, the fan runs at idle speed, so at
70%.
The temperature can fall or rise within the set hysteresis
range of -/+ 2 °C. The fan speed will then decrease or
increase by 15% per degree. After all, the range is 60%,
divided by a range of 4 (- 2 °C and + 2 °C). So if the
temperature drops by one degree to 26 °C, the fan
speed will decrease by 15% in proportion to the idle
speed, and therefore decrease to 55% (70% minus 15%).
If the measured value is 28 °C, the fan speed increases
by 15% in proportion to the idle speed. The fan speed
becomes 85%. If the measured value rises to 29 °C, the
speed increases again by 15% to the maximum fan
speed.

4.7 Reset minimum/maximum values

You can delete the stored measured minimum and
maximum temperature and humidity values in two ways.
Firstly, by turning the knob "Temp Set". By turning this
knob fully closed and open two times within 3 seconds,
the measured minimum and maximum values are
deleted:
turn to 15 °C
•
turn to 35 °C
•
turn to 15 °C
