desired minimum fan speed "Min Fan Speed" (10% –
100%) by turning the left knob.

4.2 Maximum fan speed

Turn the middle knob to set the desired maximum fan
speed "Max Fan Speed" (50% – 100%).

4.3 Temperature

Turn the right knob to set the desired room temperature
"Temp" (15 °C – 35 °C).

4.4 Hysteresis

During the start-up of the Clima Micro Plus Min/Max
Fan Speed you can set the hysteresis (1 °C - 5 °C). To do
this, complete the following steps:
1. Put the plug of the Clima Micro Plus Min/Max Fan
Speed into an electrical outlet. The next screens are
displayed:
TechGrow
Micro
Plus
2. Put a precision screwdriver (or paper clip) in the
small round hole on the back of the Clima Micro
Plus Min/Max Fan Speed and press carefully during
start-up. The next screen appears:
Hysteres
1c
3. Press repeatedly until the desired hysteresis value
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.

4.5 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 set maximum fan speed. 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 set 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
capacity.
Min Max Idle
30% 80% 55%
20% 90% 55%
40% 100% 70%
50% 80% 65%

4.6 Reset minimum/maximum values

You can delete the stored measured minimum and
maximum temperature 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:
