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 configure the controller. In service mode, in item F.14 set 2, and F.15 and F.16 should
be set based on the sensor specification.
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.
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 controller.
