CSC-20: New product family of decentralised CO2 controls
The flexible connection concept with separate connections for supply and exhaust air elements ensures that both of the applications described above can be fully met. Besides 230 V actuators, 0...10 V EC motors as well as multi-stage fans can also be controlled in an automated, needs-based way.
More information about the topic of possible applications CO2 can be obtained in our following blog posts:

The CSC-20 YUGO has an integrated CO2 sensor with a measuring range of up to 10,000 ppm and is therefore suitable for applications in mechanical and plant engineering as well as for building services engineering. Appropriate limit and switching values for the respective application can be configured via the display and the operating keys of the CO2 control. But automatic ventilation is not the only operating mode - the integrated timer function also allows for individual ventilation cycles. For more information on the operating modes, please read the next sections.

Fields of application of CO2 controls and switches
|
Wherever people spend long periods of time indoors, the CO2 level increases. |
|
Houses and buildings
|
Industry and commerce
|
Operating modes and supported actuators
| Automatic mode with hysteresis |
When the set CO2 limit value is reached, the actuators are triggered automatically. If the CO2 concentration has dropped to a safe or healthy level below the limit value, the actuators are automatically switched off again. |
| Manual mode | Enables the actuators to be switched on independently from the currently measured CO2 concentration. |
| Pause mode | Interrupts the automatic mode and switches off the actuators. |
| Configuration mode | While the device will be configured, the actuators remain switched off. |
| Error mode | In case of a sensor error, the device switches to the error mode. Then, the actuators remain or are switched off. |
A total of 6 actuator configurations, corresponding to the possible circuits, can be selected via the configuration menu. Depending on the selected actuator, it is possible to set appropriate CO2 limit values.
| Programme no. | Actuators used for supply and exhaust air* |
| 1 | One-step fan (230 V) |
| 2 | Two-step fan (230 V) |
| 3 | Electric window opener or actuator / flap drive / flap actuator |
| 4 | One-step fan and window opener |
| 5 | 0…10 V speed-controlled fan |
| 6 | 0…10 V speed-controlled fan and window opener |
*At least one actuator must be connected; electrical circuit according to the wiring diagrams
