HarmonEE
■ System integration
– TXI1.OPEN module for integration into
DESIGO PX
– Implemented P1 protocol for Apogee
from Siemens
– Third-party systems can easily commu-
nicate with the SED2 via USS-Talk or N2
■ LM communication
– The module conforms to the LM
regulations with regard to Variable
Speed Drive Prole Number 6010
– Standard Network Variable Types
(SNVTs) are used for communication
– Configuration, control and monitoring
via the LonTalk® network
– 48 SNTVs are preconfigured
– Direct integration into control systems
– Snap-on facility for straightforward
installation and easy integration
■ TXI1.OPEN module
– General control: On/off and preselected
setpoint (in frequency, % PID or pres-
sure); both with checkback signal
– SED2 data points: Output frequency
(Hz), output current (A), cumulated
energy (kWh), and output (kW)
– Errors: Display and acknowledgement
■ PROFIBUS module
– For a complete PROFIBUS connection
with ≤12MBaud
– With an operator panel (AOP/BOP)
snapped on the PROFIBUS module,
remote communication and operation
can be combined with SED2
– Snap-on facility for straightforward
and easy installation
■ HarmonEE
– Calculator software tool for harmonics
generated by the variable speed drive
■ EasyComm commissioning and
engineering software
– Integrated commissioning assistant
to parameterize easy to complex appli-
cations without parameter know-how
– Clear and easy user guidance to reduce
errors, effort and costs

Application examples
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 and fire 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.
