• Also available with temperature measurement of the
exhaust air for erimix system
• Also available in an insulated design

DESIGN
KSA is available as standard in a circular design for sizes 100500. A rectangular model is built onto a flap damper and can
be provided on most markets in sizes up to 2000 mm x 1200
mm. The circular model is also available in an insulated design
to fit silencer CLA/CLB, see figure 1. Circular sizes have a shutoff damper for class 4 air tightness, rectangular in class 3 air
tightness, enclosure class conforming to IP30. KSA is supplied
as standard completely assembled and configured for its intended purpose as a slave controller or constant flow regulator. KSA has integrated summation of the air flow rate up to
5 master units, only applies with digital transfer of the air flow
rate. KSA is supplied with an integrated temperature sensor
when used in the erimix system with exhaust air temperature
control of the supply air.
Figure 1. KSA insulated design and sound attenuator CLA/
CLB.
MATERIALS AND SURFACE TREATMENT
All sheet metal parts are in galvanized sheet steel. All plastic
parts are completely PVC free and are generally made of ABSplastic.
ACCESSORIES
Operator panel KOP for reading data.
Mounting sleeve FSR to aid dismantling when cleaning the
duct system.
INSTALLATION
KSA can be installed in any position in climate-conditioned areas. The pressure sensor position should be arranged so that
its diaphragm is always in the vertical position when installed
horizontally; this is done by loosening the pressure sensor’s
securing screws and changing the position, see figure 3. KSA
is connected to the duct system using the mounting sleeve
FSR on ducts that must be cleaned. KSA should always be installed with straight sections. Electrical connection is carried
out as per the wiring diagram KSA.
Figure 2. KSA for rectangular ducts.
COMMISSIONING
KSA is configured at the factory and receives all data for air
flow via the network (alternatively analogue) from the master
unit (KZM or KRF).
MAINTENANCE
Dirty products may be cleaned by wiping or vacuum cleaning
only.
DECLARATIONS
The product is CE marked.
CE declaration and Environmental Product Declaration are
available from our website.
Standard: Conforms to LONMARK® Interoperability Guidelines and LONMARK® Functional Profile: VAV Controller.

PLANNING
A comprehensive planning guide that describes the overall
e.r.i.c. concept is given in the technical section.
KSA (1) is a slave controller for flow regulation in branch
ducts. Also see KZM (2) or KRF (2) which act as the master unit
to KSA.
The transfer of the air flow rate from the master unit can take
place either via LONTALK® or analogue via the flow sensor on
the master unit. The slave flow deviations are programmed on
the master unit with digital transfer, while with analogue
transfer it occurs on the slave controller.
Using digital transfer of the slave flow up to 5 master units can
be bound to the slave unit, which adds all the sub-flows and
regulates against the total flow.
KSA can also be used as a constant flow regulator, freestanding or connected to a LON-net, which provides the ability to
monitor and change data.

CONNECTION
KSA is connected to a supply voltage of 24 V AC and
LONTALK® as set out in the wiring diagram.
Wire cross-section requirements
Supply voltage (24 V AC) with max fuse 6 A requires ≥1.5
mm2. Signal wiring from connected units max 30 m requires
0.7 mm2. Connection to LONTALK® TP/FT-10 Free Topology
Channel should be made using twisted pair cable.

TECHNICAL DATA
Air flow capacity
The product’s air flow capacity is important in planning when
air flow measurement is included in the product, see
diagram. The normal working velocity range lies between
1.5-8 m/s in the duct. The upper control limit lies at approx.
13 m/s, but then gives significantly increased pressure losses
and sound problems.

Sound power level
The diagram for the different sizes shows the total sound
power (LWtotdB), as a function of the air flow and pressure
drop across the damper. By correcting LWtot with the correction factors from Table 1 the sound power levels are obtained
for respective octave bands (LW = LWtot + KOK).
Transmitted sound
The sound transmitted from KSA is calculated according to
the formula:
LWout = LWduct + Ktrans
Data refers to non-insulated KSA and is related to the duct
length that KSA makes up.

Lonmark objects and network variables
The standard object for KSA with regulator KCP is shown in
the figure below. Only a few of these network variables are
used for the application handled by KSA. Further information
about the use of variables can be found in the commissioning
instructions for the e.r.i.c. system and in the Technical Manual. All documents are available for download from our website. The regulator is LONMARK®-approved. “xif-files” are
available for download from our website.
