PROFIBUS module
Demand-controlled fans
Energy-efficient realization of customer-
specific demands: Air quality sensors, control-
lers as well as the know-how from Siemens
guarantee an on-demand operation of your
ventilation system. The fans are controlled
exactly to the actual demand of fresh air.
Thus, cost and energy savings of up to 60%
are possible.
Demand-controlled pumps
Pumps can only be operated efficiently if
the control strategy of the pump and the
hydraulic network are accurately harmo-
nized. In addition, an optimum layout of the
pump and the right placing of the pressure
detector are decisive for operation at optimal
cost. Siemens possesses broad application
know-how and provides you with the right
controllers to reduce your operating costs
and energy consumption.
Optimum interaction of ventilation system andre control panel
Without additional control logics, the SED2
support two operating modes. In the comfort
mode, the supply air and extract air fans are
controlled exactly according to the actual
demand. Thus, a high level of comfort is
guaranteed at lowest energy consumption.
If a fire control panel signals a fire, the SED2
change their operating mode to the fire emer-
gency mode. This operating mode ensures that
rooms for example are specifically controlled
by means of overpressure to make sure escape
routes are kept free of smoke.
