REF 819756/819757
The type C 2-speed remote controller is a safety device for controlling air flow regulation
at low and high speed depending on the position of the sash.
A speed sensor is used to determine the flow rate. Audible and visual alarm is set off in
case of insufficient speed or too high sash height and other malfunctions. The controller
engages the second gear by means of a contactor placed in the path of the sash.
The remote HMI is used to control the fume cupboard ventilation and to carry out the
following adjustments on site.
This controller complies with EN 14175 and RoHS Standards.
