The ideal solution for ventilation of the premises requiring permanent temperature control, i.e. greenhouses. 

With the temperature sensor integrated inside the fan air duct

The fan front panel has the following control knobs:

* speed control knob for setting the motor speed

* thermostat control knob for setting the temperature set point;

The fan with the electronic temperature and speed control module provides automatic control of the motor speed (air capacity) depending on air temperature in the air duct or in the room.

Set the desired air temperature (thermostat set point) by turning the thermostat control knob. Set the required minimum impeller speed (air flow) by turning the speed control knob. The motor switches to maximum speed (maximum air flow) as the temperature reaches and exceeds the set temperature set point.

The motor switches to the preset lower speed as the temperature drops down below the temperature set point. To avoid frequent motor speed switches when the air temperature in the duct is equal to the set temperature point, the speed switch delay is activated.
