Controls
The controller software is designed to handle Four (4) different applications.
Each application has its own set of parameters (input value range, set points, p-band, min and max
speeds, etc.) and control function. The application is preselected at factory but can be changed like the
other parameters using the CTRL-DSP.
When the device is enabled, the fan speeds are controlled by the value of the 0-10VDC CONTROL INPUT
SIGNAL, depending on the application: (e.g. CO
2
sensor, pressure control, BMS or manual)
APPLICATIONS
0-10V control
Control input signal 0-10VDC determines the fans speed 0-100% of configured max. speed.
High input signal gives high fan speed.
CO
2
control
The room’s CO
2
content (Control input signal 0-10VDC mapped to CO
2
sensor range) is controlled by a P
controller (P band). High CO
2
rate gives high fan speed.
Pressure control
Duct air pressure (Control input signal 0-10VDC mapped to pressure sensor range) is controlled by a PID
controller (Proportional, Integrating and Derivating).
High pressure value gives low fan speed
Manual fan speed control
The fan speed is set manually using the CTRL-DSP’s UP and DOWN buttons (resolution 1%).
Fixed speed
With the unit Enabled and Fixed Speed input open, fans will run at fixed speed, settable in parameter P06
