Air intake sets with electric heater are used to provide fresh air from outside to the building without the risk of cooling the room down. The special heating module used turns itself on when the temperature outside falls under 8±4 [ºC]. During the whole time of working the present power consumption is adjusted according to the actual temperature outside - so the power consumption can be minimalised. when the temperature rises above 8±4 [ºC] thermostat will turn the heating module off. 
Max power: 280 [W], Voltage: 230 [V] 50 [Hz] AC, Efficiency: 40 [m³ /h]
