Ventilation control unit LZ1 2.5 A 24 V DC (660027)

Aumüller LZ1 2,5 A ventilation control unit 24 V DC (660027)

The Aumüller ventilation control unit LZ1 2,5 A is used for power supply and control of 24 V DC window actuators for daily natural ventilation. With one actuator line and a maximum output current of 2.5 A, this compact control unit is particularly suitable for individual windows or smaller groups of windows.

Operation is carried out via a ventilation push-button line with three priority levels. In addition, a 24 V DC output with 500 mA is available, for example for supplying a rain sensor.

Via a DIP switch, the input with the lowest priority can optionally be set to latching mode or dead-man operation. The inputs of several LZ1 and/or LZ6 ventilation control units can be connected in parallel, making it possible to implement more extensive ventilation solutions as well.
