6.2.1 Speed setting
The speed is set using the potentiometer built into the unit or otherwise using the REB ECOWATT
®
or
CVF remote control.
By default
, the unit is set to its maximum speed, in bold in the table below. The
potentiometer built into the unit is used to modify the turbine’s speed to set the air volume.
