The Helios KWL 45 BEU is a dedicated operating element designed to manage the control of multiple Helios ventilation units. When used in conjunction with a suitable switched-mode power supply, it allows for the connection and coordinated operation of up to 6 device units.
For installations requiring control of more than 6 units, the system can be expanded with the addition of a KWL 45 SNU, increasing the capacity to a maximum of 8 devices per control module. This ensures flexibility in system design for larger residential or light commercial applications.
The KWL 45 BEU meets the safety and performance standards outlined in DIN EN 60335 – 1, making it a reliable and compliant component for Helios heat recovery ventilation systems.
