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 exhaust fan according to the temperature and humidity settings you have set.

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