Three Speed Switch
A fixed position switch which allows the user to control the speed of airflow for when the building is occuppied, not occupied or when a boost is necessary. The flow rates can be adjusted (preset at installation) depending on the size of the property and the ventilation requirements. The red LED warning light illuminates when filters need replacing, this same LED will flash to indicate a fault on the machine.

Wireless Switch
This is a four position wireless control, allowing the same three speeds as the wired switch above but in addition it has a timer mode allowing timed operations. It is possible to have more than one transmitter going to the same receiver giving the user control from several rooms.

Optional Controls

With this board you can connect and manage various accessories including humidity sensors, co² sensors and smoke detectors all of which will affect the regulation of air flow inside the heat exchanger. Using these optional components you can create a full demand controlled ventilation system.
