3) Fan control when s
computer via Modb
This controller allows controlling both device and 0..10VDC fan. In service menu, select desired speed control
method (F.01). If control based on preset speeds is selected, then select them in menu items F.03, F.04, F.05,
F.06.
4) Pressure contro
computer via Modbu
Desired pressure can be maintained by connecting 0..10VDC fan and 0..10VDC pressure converter directly to
the controller. Control and pressure sensor parameters can be changed in controller. When controller is used as
Modbus slave device, it allows controlling all parameters and monitoring of pressure sensor readings.
For pressure based control, select the following parameters in the service menu:
• F.14 - 1
• F.15 and F.16 -based on pressure converter parameters
• F.11, F.12 and F.13 - (PID control ratios). If pressure is maintained incorrectly, these parameters can be
adjusted.
•• F.07 - F.10 - nurodome fi ksuotus greičius Pa.
5) CO2 control
This controller allows controlling level of carbon dioxide (CO2) in a room. Connect 0..10VDC CO2 sensor di-
rectly to the controller and confi gure the controller. In service mode, in item F.14 set 2, and F.15 and F.16 should
be set based on the sensor specifi cation.
After CO2 sensor is connected and required parameters are set in the service menu, select desired CO2
level (P.05) and allowed difference from the set (P.05) limit in the user menu. If allowed difference is exceeded,
controller will automatically start fans at maximum (4) speed and "CO2" will be shown in digital display. After set
CO2 level (P.05) is reached, controller will return to previous mode.
