149-CD-POT
149-CD-POT
The 149-CD-POT is a commissiong device designed to be used with our EC range of fans.
This device will be as standard with our box fan range from May 2018.
The device will allow the for the installer to set the maximum operating speed of the fan that it is
connected to.
The installer or commissioning engineer can adjust the fan speed using the potentiometer built onto the
149-CD-POT board. This potentionmeter can either be used for single speed adjustment or to set a
maximum speed for the fan to operate at when an external control source is used.
If external speed control is required, the jumper connection next to the potentionmeter on the board
would need to be removed, the installer can then connect to ST1 (using the diagram provided).
When an external speed control is fitted, the maximum speed setting available to the external control is
limited by the potentiometer setting of the commissioning device.
