During engineering, the devices on the floor level network are defined as data points in
the FLN master's process image:

The following point types are available to image the FLN devices to the FLN master.
They contain the following information:
Point types Information
TEC rooms
@TCR
TEC rooms (@TCR) comprise 1 to max. 10 TEC controllers (TEC1,
TEC2, etc.) according to their arrangement in the building. TEC
rooms contain information such as:
– The most important actual values of the room.
– Defaults from the higher group.
– FLN addresses of the allocated TEC, etc..
Comment: Master-slave principle if more than 1 controller in room.
TEC groups
@TCG
TEC groups (@TCG) comprise 1 to max. 20 TEC rooms according
to the climatic/technical zones or occupancy profiles. TEC groups
contain information such as:
– Operating mode (Comfort, Comfort Reduced, Economy, Standby)
and setpoints.
– Setpoint correction according to outside air temperature.
– Minimum, maximum, median values for room temperatures, etc..
Energy demand
@TED
The energy demand points (@TEC) in the FLN master gather the
energy demand of individual TECs and forward the demand.
– Up to 30 TECs featuring the same type of energy (e.g. hot water,
chilled air, etc.) are grouped in one TED.
– Calculation of minimum, median, and maximum value by TED.
Link points
@AO / @AI
I/O points not used by the TEC application can, for example, be
used for blinds or main light switches, and be integrated as link
points (@AOx or @AIx).
RWI points
@RWI
RWI points each image an AEROGYR device (@RWIx) and contain
information such as the operating mode, setpoints, actual values,
fault messages, manipulated variables, etc..
Via the integrated data points, the FLN master executes the central control and
coordination tasks for the FLN devices as programmed:
• Coordination of TEC and RWI with respect to scheduler programs, operating modes,
and setpoints.
• Coordination of central air and energy handling, and of the supervision and
protection functions.
• Special functions for room management: Night ventilation, smoke extraction, etc..
• Demand-controlled ventilation: Room air quality, pressure control (VAV).
