Sales arguments 1 Integrated room-primary application: Siemens offers an integrated application solution for small and medi-
um-size school buildings which also includes the primary HVAC control part – a fully integrated and tested
solution with products from a single source.
2 Energy savings through individual room temperature control: Due to individual room control, up to 30%
heating energy can be saved.
3 Energy savings through time programs: Time programs for each room automatically reduce the room
temperature during the night, on weekends and during holiday periods.
4 Energy savings thanks to window contact: Room heating is automatically stopped if the window is left
open. So, the actuator will not open to warm up outside air.
5 Energy savings through presence survey: A presence detector ensures that the lights are automatically
switched off if nobody is in the room. Turning off the lights will never be forgotten when people are leaving.
Thanks to the presence detector, up to 20% lighting energy can be saved.
In addition, when no presence is detected, the room temperature will automatically be lowered by 1 to 2 K.
Each degree of temperature reduction can save up to 6% heating energy.
6 Energy savings through lighting control: Lighting control helps ensure that only as much artificial light as
necessary is used. Together with the natural light,
the users will get optimal lighting conditions and another 10
to 20% lighting energy can be saved.
7 Energy savings through weather monitoring:
A weather station protects the blinds from storm damage and
ensures that the blinds are down to protect the room from excessive solar irradiance in the summer. In cold
winter nights, the blinds are automatically lowered to improve the building’s thermal i
nsulation.
8 Energy savings through automatic data exchange: Synco living allows the straightforward integration of
Synco 700 controllers via KNX bus and therefore automatic data exchange between room and HVAC primary
plant. With automatic data exchange, the HVAC primary controllers provide only as much heat (or cooling
energy) as demanded by the room controllers. This means that valuable energy can be saved.
9 Remote monitoring and control: Occupancy, lighting, the blinds and temperatures of each room can be
monitored and adjusted on a touch panel or Web browser from a central location or when on the move. An
energy efficiency indicator informs the operator when settings are outside predefined limits. So, wrong or
temporarily changed settings will never be forgotten and the building is kept under control at all times.
10 Reduced installation effort: Wireless KNX RF communication between the Synco living devices including
KNX TP1 bus reduces the installation effort and ensures a high level of flexibility. This technology is ideal for
renovation projects or building types where rooms need to be easily reallocated.
