Operating point
Select fan type
CPR-2
Controller
The CPR-2 controller controls the fan rotation speed, stabilizing the pressure difference between the ventilation duct and the reference pressure.
Application
The CPR-2 controller controls the fan rotation speed, stabilizing the pressure difference between the ventilation duct and the reference pressure.
The CPR-2 has an implemented self-tuning PI controller with a control quality deterioration detection module and automatic restarting of tuning. The controller selects the settings so as to ensure optimal operation of the fan, at the same time ensuring maximum comfort of using the system.
