Alarm functions
If there is a
fire alarm
from a smoke detector, ventilation is activated and cannot be
influenced either by the automatic controls or manually.
Ventilation settings
Ventilation according to
temperature, humidity and CO
2
is checked every second.
For exhaust units, the power is increased as the values above the setpoint increase.
However, the power is not reduced until the new required ventilation intensity is 20%
lower than the current intensity (delay/hysteresis). The set minimum and maximum
ventilation intensity is maintained.
For supply air units, the ventilation flap is opened as soon as one of the values is above
setpoint. However, it is not closed again until the new required ventilation intensity is
20% lower than the current intensity (delay/hysteresis).
Set automatic mode
Sensor selection:
Shows the indoor sensor, which is evaluated for the controls. Touch the field and select
a sensor.
Default setting: No sensor.
If no sensor is selected, the indoor temperature and humidity are not taken into ac-
count for the controls.
Indoor temperature (ventilation):
Shows the indoor temperature from which ventilation is active. The setting is only ac-
tive if an indoor sensor is selected. Touch the field to adjust the indoor temperature.
Select
OFF
if the ventilation should not depend on the indoor temperature.
Change to
ON
to set the desired temperature. The ventilation starts as soon as the tem-
perature exceeds the set value. The ventilation is stopped if the temperature sinks by
more than 2.0°C below the pre-set value (hysteresis).
Humidity:
Shows the humidity from which ventilation is active. The setting is only active if an in-
door sensor is selected. Touch the field to adjust the humidity.
Select
OFF
if the ventilation should not depend on the humidity.
Change to
ON
to set the desired humidity. The ventilation starts as soon as the humid-
ity exceeds the set value. The ventilation is stopped if the humidity sinks by more than
3.0% under the pre-set value (hysteresis).
