Siemens Climatix Series Short Manual

2.2.2 Supply air/extract air fan control
Fans can be directly controlled, pressure-controlled, flow controlled or controlled as
master-slave. Common or separate outputs are used depending on the
configuration.
Fans may include an alarm and/or active feedback contact.
Up to 3 setpoints per fan can be defaulted for controlled fans and achieving the
setpoints can be monitored.
You can influence the fan stage (speed) by room temperature, air quality, humidity,
outside air temperature or supply air temperature.
Operating hours are recorded separately. A message can be triggered upon reaching
a certain number of operating hours for the supply air fan.
