Using this remote controller and CO

transmitter it is possible to reduce inside carbon dioxide level.
This controller allows controlling both device and 0..10 VDC 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.
NOTE: The air quality converters and remote controller (when fan is controlled) must be powered
from a separate power source. It is not supplied with the remote.

Desired pressure can be maintained by connecting 0..10 VDC fan and 0..10 VDC pressure convert-
er directly to the controller. Control and pressure sensor parameters can be changed in controller.
When controller is used as Modbus slave device (air handling unit is not controlled by this principle),
it allows controlling all parameters and monitoring of pressure sensor readings.
For pressure based control, select the following parameters in the service menu:
F.01 - 2
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.0 - F.10 - seting of xed speeds (supports di󰀨erent pressure level in Pa)
F.43 -1 - 0..10VDC output activated.
