Ventilation
The secondary folder Ventilation control – Settings is the same for both CO
2
equivalente and TVOC
concentration.
It
includes the following parameters:

Communication object dimension;

Min. change of value to send [%];

Cyclic sending interval;

Value < threshold 1;

Threshold 1 < value < threshold 2;

Threshold 2 < value < threshold 3;

Threshold 3 < value;

CO
2
- Hysteresis (for continuous speed);

Min. CO
2
[ppm] value (for continuous speed);

Max. CO
2
[ppm] value (for continuous speed);

CO
2
Min. ventilation speed [%] output (for continuous speed);

CO
2
Max. ventilation speed [%] output (for continuous speed);

CO
2
ventilation lock;

Disable ventilation from bus;

Time scheduled ventilation.
The following condition has to be true:
o
Internal sensors

CO
2
sensor = enabled;
o
CO
2
control

Thresholds

CO
2
ventilation = enabled.
Or:
o
Internal sensors

TVOC sensor = enabled;
o
TVOC control

TVOC Thresholds

TVOC ventilation = enabled.
Or both the above conditions.
