3-phases - COP constant pressure control
During operation at constant pressure, the controller regulates the speed of the roof fan to obtain the set
pressure. If the display is present on the roof fan, it will show you the pressure in Pa. The pressure set
point can be adjusted by the potentiometer in the controller, by a CVF ON/OFF + variation remote con-
trol, by an external 0-10V output or by Modbus BMS.
