REACT
Planning
Control – Example
General
• Designed for demand-controlled ventilation in rooms
with variable loads.
• Intended for comfort ventilation.
• Humid, cold or aggressive environments should be
avoided.
• Environmental and/or air temperatures should be
within 0 - 50 °C.
• Can be installed in both supply and extraxt air systems.
• Pressure-independent but requires a minimum air flow
equivalent to the open damper pressure drop to function properly.
• Factory calibrated with a nominal air flow (Qnom )
• When carrying out design work, the minimum air flow
required by REACT has to be taken in to consideration.
Control
• Controlled by heat, carbon dioxide or occupancy.
• The factory setting is always 0-100% = 0 l/s – Qnom.
• Can be forced controlled to:
– maximum and minimum air flow.
– fully open or fully closed damper
• When used for slave control, slave and master units
must be of the same dimension.
• Can be used as a constant flow damper.
(Qmax = 0 and Qmin = desired constant flow)
• Delivered with 0 - 10V set value and actual value signal.
• Adjustable to 2 - 10V set value and actual value signal.
• REACT can be analogically connected to Building
Management Systems (BMS)
• Possible to obtain with Modbus control
• Possibility to obtain REACT with spring return actuator.
Electrical data
NOTE: To obtain the correct functionality of the control
and regulating equipment it is of great importance that all
interconnected regulating equipment has the same polarity.
Feed voltage
Below, a couple of examples are shown of how REACT can
work in a demand-controlled ventilation system. When
regulation via a CO2 sensor is chosen, the room thermostat is
excluded as DETECT Q has an integrated temperature sensor
that combines its output with the value from the CO2 sensor.
The greatest signal from DETECT Q is sent to REACT to
regulate the air flow. With the help of the presence detector
DETECT O, the 0-10 V signal can be susopended so that the
REACT unit regulates down to a minimum air flow when a
room is unoccupied. DETECT O can also be connected so
that REACT shuts down completely.
Slave control - Example
A REACT unit can be slave controlled from another REACT
or from REACT CU. Slave control can also be achieved by
parallel connection, i.e. by connecting the room
thermostat signal to both the extract and supply air units.
Parallel connection is recommended because the control
signals are sent to both units at the same time and air
flow can be freely set within the working range of REACT.
Slave control is limited as the slave unit cannot have a
greater air flow than the master unit and because lower
flows can only be obtained as a percentage of the master
unit air flow. In systems with REACT CU as sensor unit,
the slave control principle is always applicable.

Sound power level
• Graphs show the total sound power (LWtotdB), as a function of the velocity and pressure drop across the damper.
• By correcting LWtot with the correction factors from the
tables, the sound power levels for respective octave
bands will be obtained(LW = LWtot + KOK ).

Measurement accuracy – all versions
• At Qmin a measurement pressure of 1 Pa is obtained with
a measurement accuracy of ± 5-20%
• A minimum measuring pressure of 5 Pa is recommended
which corresponds to about 1.7 m / s in the duct with an
accuracy of ± 5-10%.
• At duct speeds between 2.5-9 m/s, ± 5% measurement
accuracy of flow is achieved.
• For rectangular dampers recommended minimum air
flow Q = 5 Pa
• Maximum air flow is Qnom. On request, Qnom can be
increased to obtain increased Qmax. The consequence of
an increased Qnom is less accuracy in the lower flow area.
• NOTE: Increased Qnom gives higher duct speeds and thereby
generates higher sound levels.

Air flows and measures – rectangular version
Sound data – rectangular version
B = Width, H = Height
Sound power level
• Graph shows the total sound power (LWtotdB), as a function of the velocity and pressure drop across the damper.
• By correcting LWtot with the correction factors from
each table below, sound power levels for respective
octave bands will be obtained(LW = LWtot + KOK + Kk).

Air flow – Pressure drop – Sound level
• Data applies for sound generated in ducts.
• Minimum flow applies at 1.5-2 m/s in the duct, minimum 5 Pa measurement pressure.
• Calculate the face velocity across the damper and read
the sound data and pressure drop at an appropriate
damper position.
• 100% corresponds to fully open damper.
