Warning/Caution!
Risk of crushing
Application area
The product is a pressure regulating damper designed for
comfort ventilation indoors. The product is used to regulate the
supply air or exhaust air pressure in ventilation ducts.
The product may not be used for anything other than its
intended use.
General
Read through the entire instructions for use before you
install/use the product and save the instructions for future
reference. It is not permissible to make changes or modify
this product other than those specified in this document.
The packaging contains the following
items:
1 x REACT P-X
1 x Instructions for use
Protective equipment
Always use appropriate personal protective equipment
for the work in question, in the form of gloves, respirators
and protective glasses during handling, installation,
cleaning and service/maintenance.
Electrical safety
Permitted voltage, see “Electrical data”. It is not permissible
to insert foreign objects into the product’s contactor
connections or the electronics's ventilation openings; risk
for short circuiting.
24 V isolation transformer to be connected should comply with
the provisions of IEC 61558-1.
Cable sizing must be carried out for cabling between the product
and the power supply source.
Disconnect the power supply when working on products that
are not required to run in production.
Always follow the local/national rules for who shall be permitted
to carry out this type of electrical installation.
Other risk
When the product is voltage fed, the damper will be
either open or close and there can be a certain risk
for pinch injuries, for example, on the fingers if these
are placed between the damper blade and ventilation
duct when the damper blade rotates. The product’s
actuator is equipped with a release button that permits
manual control of the damper blade, always ensure this
is activated before working on the internal parts of the
damper.
If the product is equipped with a spring return actuator there is
no release button, manual control is performed using the sup-
plied hex key where the damper blade is cranked to the required
position and then locked. Do not forget to disable the lock after
working on it.
Handling
• Always use appropriate transport and lifting devices when the
product is to be handled to reduce ergonomic loads.
• The product must be handled with care.
Installation
• Moist, cold and aggressive environments must be avoided.
• Avoid installing the product near a heat source.
• Assemble the product according to applicable industry
regulations.
• Install the product so that it is not accessible by unauthorized
persons, for example above a suspended ceiling.
• Install the product for easy access during service/maintenance.
• Supplement the duct system with a cleaning hatch in the
vicinity of the product to facilitate cleaning.
• If the product is mounted above a fixed ceiling, the inspection
hatch must be located so that the product is accessible for
inspection.
• If the product is mounted so that it is possible to gain access
to the inside of the product, it must be supplemented with
appropriate protection, for example, a ventilation unit.
• If the product is mounted in cold areas, the whole product
must be insulated on the outside against condensation.
• For installation, the accessory FSR is recommended.
• The product can be installed position-independent.
• It is recommended to mount the product so that the
product’s display is visible.
• The product must be laid down prior to installation so that it
cannot fall over.
• Check to make sure that the product does not have any
visible defects.
• Check that the product is properly secured after it has been
installed.
• Use the product’s eyes to secure the cables with cable ties.
• Check that all cables are properly secured in place after
installation.
• Check that the actuator/controller is properly mounted in
place.

Installation – all designs
• The product’s pressure measurement requires spacing
as per the installation figures.
• In unfavourable conditions before or with disruption,
the product’s tolerances cannot be guaranteed.
• Instructions for Use are supplied with the product on
delivery, but can also be downloaded from www.
swegon.com.
Installation – circular version
• Installation is position dependent.
• Can be installed horizontally or vertically.

Function Description
Addr
Enables you to set the actuator's Modbus address, by turning the "edit wheel". It
is possible to set the address from 1 till 247. If you turn the value selector to end
stop "+", the display will show a "2". This makes it possible to select the second
level. If you select the second level, this is indicated in the display by a small
circle.
The following functions are available at the second level:
Pres/Unit Return to previous level
Pmin Not used.
Pmax Not used.
Test Not used.
Mode Shows the angle of the rotation (0…255 digital 0....100%)
Addr. Used for selecting communication settings for Modbus. See table below.

Cleaning
Ideally, the product should be cleaned in connection with
the cleaning of the rest of the ventilation system.
Cleaning of electrical components
• If needed, use a dry cloth to clean the components.
• Never use water, detergent and cleaning solvent or a
vacuum cleaner.
External cleaning
• If necessary use tepid water and a well-wrung cloth.
• Never use detergent and cleaning solvent or a vacuum
cleaner.
Internal cleaning
• When cleaning the ventilation system, the product
must be dismantled if there are no cleaning hatches
close to the product.
• Cleaning equipment such as whisks and the like must
not be fed through the product.
• If necessary remove dust and other particles that can
be present in the product.
• Never use detergent and cleaning solvent or a vacuum
cleaner.
Service/maintenance
• The product does not require any maintenance, except
for any cleaning when necessary.
• In connection with a service, mandatory ventilation
inspection or cleaning of the ventilation system, check
that the general condition of the product appears to be
good. Pay particular attention to the suspension, cables
and that they sit firmly in place.
• It is not permissible to open or repair electrical
components.
• If you suspect that the product or a component is
defective, please contact Swegon.
• A defective product or component must be replaced by
an original spare part from Swegon.
Materials and surface treatment
All sheet-metal parts are galvanized sheet steel (Z275).
Disposal
Waste must be handled according to local regulations.
Product warranty
The product warranty or service agreement will not be
valid/will not be extended if: (1) the product is repaired,
modified or changed, unless such repair, modification
or change has been approved by Swegon AB; or (2) the
serial number on the product has been made illegible or
is missing.
Trouble shooting
The product does not communicate over Modbus
• Make sure that the product is energized.
• Check the product's Modbus connection.
• Check the product's communication settings.
• Check that the product has the right and unique
Modbus address.
The product shows the incorrect/no air pressure
• Make sure that the product is energized.
• Check that the product’s set size corresponds with the
physical size.
• Make sure that the product is installed according to the
recommended distance to disruptions, see “Installation”.
• Check that there is an air flow.
• Make sure that the product is correctly oriented in
terms of air direction. The air flow must follow the
instructions on the product.
• Check that the measuring tube is mounted correctly,
plus for supply air function or minus for extract air
function.
• Check that the measuring tubes are undamaged and
not creased.
• Check the pressure in the measuring tube. Check the
pressure in the measuring nipple.
The product does not regulate the air pressure
• Make sure that the product is energized.
• Check that the damper motor has not become
detached from the damper spindle.
• Check that the damper motor works by pressing in
the motor’s release button, turn the damper spindle,
release the release knob and then see whether the
damper motor starts to move.
• Check that the product is connected correctly.
• Check that the product is not force controlled.
