Page 7: System Overview: Pure Controller
Integrated indicator lights mean that the switch acts simultaneously as a visual feedback / display for the user. The Pure controller can be used either as a base control unit or with additional sensors connected. When used as a base control unit, there is a choice of operating modes for the ventilation unit and the air flow can be set at 3 predefined levels. -
Page 8: Construction
Pure controller without connected sensor technology If no sensor is connected, the operating mode and intensity of the air flow can be set on the Pure controller. The heat recovery and ventilation operating modes can be changed by moving the left-hand rocker switch back and forth 2 times. - Page 9 SYSTEM OVERVIEW: PURE CONTROLLER Pure controller with connected sensor technology If sensors are connected to the Pure controller, the range of the controller's functions increases and this also allows demand-based ventilation alongside manual ventilation. The sensor used must have a potential-free relay contact as its output.

INSTALLATION Distributing fan cables We recommend the star-shaped connection of fans to the Pure controller. The distribution of wires to the fan in this case takes place within the prepared mounting box using 5-pole terminal blocks. Alternatively, the fans can be connected in sequence. In this case, no distribution takes place. The fan BUS is attached directly to the terminal on the control module. -
