A step-up transformer that allows you to drive fans without the low-frequency sound at low speed.

The six stages of control help to better control the output fan according to the temperature settings you have set.

Two buttons allow setting temperature and temperature hysteresis.
Through the built-in jumper - J1 (in the box) you can choose whether, when the desired temperature is reached, the fan continues to work at minimum speed or stops. When J1 is closed - ventilation continues to work at minimum speed. When open - stops the fan completely.

It is equipped with a 4m cable with a temperature and humidity sensor, an output fan contact and a waterproof case.
