The INT800LD compact greenhouse ventilation control unit is a proportional controller that automatically controls the ventilation flaps with two separate circuits depending on the set value deviation of the indoor temperature.
Several opening limits can be set at the ventilation controller (rain, storm, minimum and maximum opening angle). The set value can be increased or decreased before sunset. Automatic storm protection is possible in combination with a vane anemometer. An INT800 WED weather station can distinguish between windward and leeward. Position feedback is not required.
