5.2 Control mode 2, CO
2
control
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:
EGT
Room sensors
EGQ
Duct sensor
The transmitter range cannot exceed 9900 ppm at 10 V DC output.
The output can be min./max. limited. The minimum value can be set between
0…99%, and the maximum value between 1…100%. If the min./max. parameters
are accidentally set to overlap one another, the max. function will be disabled
and the output will alternate between the min. value and 100%.
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.
This input must always be wired since it controls the starting and stopping of
normal control.
Wiring example: CO2-control using damper or frequency converter
