Installation CONTROL R room application
Installation in false ceilings
CONTROL Room can be installed in an optional position
in temperate spaces. CONTROL Room has digital flow
measurement that is position independent. In ducts that
must be regularly cleaned, FSR clamps should be used for
connecting the CONTROL Room components to the duct
system. CONTROL Room should always be installed with
lengths of straight duct as shown in Figure 1-2.
If CONTROL Zone is installed above a false ceiling or inside a
shaft, the product must be accessible via an inspection hatch.
Figure 1. A length of straight duct equivalent to 4 times the duct
diameter is required upstream of the unit for disturbances other
than those illustrated (such as a space bend, mixing box, etc.).
Figure 2. Requirement for lengths of straight duct in a rectangular design ahead of the unit, A > 2 x B.

Installation with sound attenuators
When CONTROL Room is installed with sound attenuators
equipped with baffle elements, it must be installed with a
straight section of ducting between the units. This applies
to circular ducts as well as rectangular ducts and on both
the inlet and outlet sides. See Figure 3.
Figure 3. Installing with a clamp (2), if a sound absorber (4)
with centre baffle is used, it should be installed with a length of
straight duct (3) that is 2xØD of the CONTROL Room (1).
Connections
Figure 4. Installation space requirements.
Electrical data
Connect the CONTROL Room to 24 V AC supply voltage and protect the circuit with a max. 6 A fuse. Wire
all other connections to ModBus and other components
according to wiring instructions as shown in figure 5.
The controller is equipped with jack-like screw terminals,
which substantially simplify installation.
Supply voltage
Connecting SLAVE Room
Wire the slave damper that is mounted in the extract air
system to the CONTROL Room controller with two separate cables: a 3-wire cable for the damper motor control
system and a LINK Modbus RJ12 cable that you can wire
to an optional contact in the controller or directly in the
pressure sensor on the supply air damper. See the wiring
diagram, Fig. 5. The 10-metre long LINK Modbus cable is
included at delivery.
Built-in relay (11)
Requirements on wire cross-sectional areas
Supply voltage with 24V AC to (1), at max. 6 A is necessary ≥ 1.0 mm2. The conductors from any peripheral
components connected must have a wire cross-sectional
area of at least 0.5 mm².

Connection for Modbus communication
CONTROL Room has two connections for Modbus communication. The connections are used in different ways,
depending on whether or not the CONTROL Room is configured for the BMS system. For more information about
network installation in the WISE system, see the separate
WISE Network manual which can be downloaded at
www.swegon.com.
Mb 1: Used only in the BMS mode.
Mb 2: Communication loop to zone dampers or Routers in
the WISE system. The connection is Modbus Slave.
Terminations
CONTROL R has built-in termination resistors that can be
activated depending on where in the system the product
is located. The termination plug should be pulled out using
small pliers and should be mounted in the correct position.
Mb 1: Used only in the BMS mode. If CONTROL R is last
in the Modbus loop; activate the termination to position
1, and otherwise to position 3.
Mb 2: CONTROL R is always a slave and should be terminated in position 1 or 3 depending on where on the
Modbus loop the product is mounted.
