The output signal will increase when the CO
2
-value rises above the setpoint value.
The CO
2
-sensor must have a 0...10 V DC output for example:
CO2RT, CO2RT-D
Room sensors
CO2DT
Duct sensor
The transmitter range cannot exceed 5000 ppm at 10 V DC output.
DI1, Start signal
Normal control will only be activated when this input is activated, closed. When the start
signal is deactivated the controller will set the output to 0.
Note: This input must always be wired since it controls the starting and stopping of normal
