CONDUCTOR
Technical Description
Our new CONDUCTOR in-house developed room control equipment is a natural result of our efforts to provide
the user with a healthy indoor climate. Different rooms
have different requirements, and this has motivated us
to develop various applications. These applications are
principally developed for the climate control of waterborne
climate systems in offices, hotels, hospitals and conference
rooms.
This is more clearly described under the different applications: W1 (office with constant airflow), W3 (Hotel with
occupancy-controlled airflow), W4.1 (Hotel/office with
occupancy-controlled airflow) and W4.2 (conference room
with air quality-controlled airflow and temperature control).
Another important building services engineering advantage
is that internal communication between room unit (RU) and
controller unit (RE) normally is wireless. This makes visible
cabling between air conditioning unit (normally one or
several comfort modules, chilled beams or periphery climate
units) unnecessary. All cable connections are hidden above
the false ceiling and all wiring is done with detachable
standard connections, i.e. screw wiring terminals.
The room thermostat has a pure design and is equipped
with a digital display that clearly shows the room setpoint
and other usual indicating symbols.
All settings can be keyed directly in the room thermostat;
however it is also possible to read the current room temperature for example. The user can change the room temperature setpoint simply by pressing buttons and the result is
immediately visible in the display.
The CONDUCTOR always offers an underlying advantage
in that you can connect it up to ModBus RTU. It will also
be possible to operate it connected up to other Swegon
ModBus units. For further particulars, get in touch with
your nearest Swegon representative.
Flexibility
• T he user can easily configure the controller functions
and parameters by means of the room thermostat.
• Wireless communication offers flexibility when deciding where to place the room thermostat.
• You can connect up to twelve pairs of actuators
(twelve for cooling + twelve for heating) to each
controller, or up to four complete units per controller
for controlling both the airflow (supply air and central
extract air, 5 damper actuators) and cooling and heating (cooling and heating circuit, valve actuators)
Reliability and Minimal Maintenance
• Input for condensation sensor that immediately cuts
off the cooling water in the event of condensate precipitation
• Regular exercising of the valves prevents the valve spindles from becoming jammed
• The controller is designed for minimizing the risk of
faulty wiring; it features quick contacts with screw
wiring terminals
• Low heat generation in incorporated components
Operation
Regulation
The controller provides proportional and integral (PI) control. The I section senses both the size and the duration
of the control deviation and adjusts the actuator opening
time accordingly. This type of control is called pulse-width
modulation (PWM). Compared with on/off control, for
instance, PWM control offers more uniform room temperature which enhances room comfort. It is possible to
adjust from PWM control to 0-10V control.
Valve actuators and valves
The actuator is of NC type (Normally-closed) but is
equipped with a so-called ”first open” function which
means that the actuator is open when it is installed. This
facilitates pressure testing and venting the water system.
The ”First open” function of the actuator is automatically disabled after approx. 6 minutes while energized. A
clicking noise will be heard after which the actuator will
change over to the NC mode and the normal regulation
function will begin.
The valves are exercised every second 24-hour period. On
these occasions, all the actuators wired to the controller
are opened fully for 3 minutes, which prevents the valve
spindles from jamming.
Data Communication
The controller has a built-in communication port that enables connection to an RS 485 network with ModBus for
supervising and override control via a main system, such
as a computer.
User Friendliness
• S imple and clear room thermostat design with digital
display that also shows cooling or heating load readings
• The actuator’s "first open" function simplifies pressure
testing and venting the water system
• The actuators indicate the position of the valve by
means of a clearly visible cylinder body (up – open
position, down – closed position.

CONDUCTOR
Technical Description
CONDUCTOR W3 – Hotels or hospitals with
occupancy-controlled airflow in fixed steps.
The CONDUCTOR W3 is an application specially designed
for controlling the indoor climate in hotel rooms and hospitals. Since the room environment should be peaceful,
quiet and offer the highest degree of comfort possible,
uniform temperature and a healthy indoor climate are significant necessities, regardless of the outdoor temperature
and season. Individual variations in room level are also
significant necessities. During certain times of the year,
high humidity may also involve risk of condensation.
CONDUCTOR W3 has what it takes to be the optimal
control and regulation equipment for hotel rooms as well
as for hospitals. CONDUCTOR W3 makes control of the
supply airflow, extract airflow and temperature possible,
in order to provide the best possible comfort in the room.
Takes prevailing circumstances into account
• The controller input for the presence detector (or a key
card reader) makes it possible to adjust the airflow and
temperature on the basis of occupancy in the room.
• In response to signals indicating an open window, the
controller regulates the valves and damper to reduce
the heating water flow and air flow respectively to a
minimum, in order to save energy.
Timed Airing
When occupancy is detected (presence detector or key
card reader) the controller sets the air dampers to the
high airflow setting to air out the room. After 5 min. the
controller returns to the auto mode and an operating condition according to the status of the sensors, see Table 2.
The user can easily change or deactivate the airing period
from the room thermostat, or from a building supervising
system.
Manual control
Whenever the CONDUCTOR W3 registers occupancy in
the room (in response to signals from a presence detector
or a key card reader) the user can regulate the airflow and
temperature by entering settings in the room thermostat.
Automatic Control
When the user leaves the room or withdraws the key
card from the card reader, the controller automatically
decreases the supply air and the extract air to a low rate
of airflow and the system returns to the auto mode. The
valve actuators for the cooling and heating water circuits
respectively are controlled in this position in response to
the status of the other sensors in the room, but with a
greater permissible differential, so-called energy saving
mode. See Table 2 for possible operating conditions.
Flow boost in the event of rapid changes in
temperature
When the difference between the present value of the
temperature and the setpoint exceeds 2 K, the controller sets the air dampers to the high airflow setting to
increase heating or cooling capacity. When the difference
has dropped to a level below the preset default value, the
air dampers return to the normal flow setting.
The temperature difference can be set to another value
via the room thermostat. The user can completely disable
the flow boost function, if required.
Operating Mode
The various operating conditions of the controller are
shown in Table 2. The various operating conditions are
based on occupant presence in the room and the status
of the window contact and condensation sensor. According to each operating condition, the controller controls
the airflow, cooling and heating until the user manually
sets the airflow or temperature. The airing function or
flow boosting function in progress (see below) are exceptions from the operating conditions specified in Table 2.
Data Communication
The control unit has a built-in communication port that
enables connection to an RS 485 network with ModBus for
supervising and override control via a building supervision
system..
When the controller is set to the auto mode, the airflow is
determined on the basis of the status of the sensors. See
Table 2. The user can also manually control the airflow
in three steps. The controller controls the supply air and
extract air damper motors by means of three voltage
levels that open the pivotal dampers to different settings.
If the system is set for a high rate of airflow, the controller
increases the flow of fresh supply air, not just the flow of
recirculated air as in many other room climate systems.
The output signals from the controller to the supply
air and extract air dampers respectively are individually
adjustable. To achieve balance in the room when the
duct pressures in the supply air and extract air ducts are
not the same, the user can easily adjust the flows via the
room thermostat.

CONDUCTOR
Technical Description
CONDUCTOR W4 – Situation-adapted,
demand control of air, cooling energy and
heating for maximum energy saving.
CONDUCTOR W4 is an optimized application for controlling waterborne cooling and heating in combination with
supply air.
The W4.2 is able to control two supply air dampers and
one extract air damper and is mainly intended for use in
conference rooms.
Since the number of occupants in conference rooms is
relatively low while the number of people present at the
meetings varies from meeting to meeting, a situationadaptable indoor climate system is required for creating
a healthy room climate and at the same time minimizing
the use of energy.
The W4.1 is able to control one supply air damper and
one extract air damper and is mainly designed for use in
hotels and offices.
Since needs differ from case to case, CONDUCTOR W4
offers optional cooling step sequences. The user has the
option of first using air to cool the room and then adding
waterborne cooling if the need arises. The user can also
opt to let chilled water cool the air first and then increase
the airflow if the need arises.
Adapting to the Situation
• The presence detector continuously checks whether
someone is in the room and adjusts the airflow between the preset min. flow and the occupancy flow.
• The CO2sensor continuously measures the air quality in
the room. When the room is occupied, the controller
variably adjusts the airflow between the preset occupancy flow and the max. permissible flow in order
to supply a sufficiently high airflow for the current
number of occupants.
• The pressure sensor measures the static air pressure on
the supply and extract air sides. The pressure reading is
used both for balancing the supply and extract air and
for controlling the damper blade positions.
• The condensation sensor located on the chilled water
supply pipe senses any actual condensation precipitation. If any condensation has formed on surfaces, all
the cooling valve actuators wired to the controller are
closed in order to stop the precipitation of condensate.
As this occurs, the controller increases the flow of supply air in order to compensate the loss of capacity until
condensation precipitation has ceased and waterborne
cooling can be resumed.
• Window contacts can be wired to the system for sensing whether a window is open or closed. If a window
should prove to be open, the controller adapts the system so that cooling, heating and ventilation is switched
off in order to avoid unnecessary energy losses. If
someone leaves a window open during a cold winter night, for instance, the system has a built-in frost
protection function that causes the heating to start up
if the room temperature drops below 10°C.

Energy Saving Control
CONDUCTOR W4 can be optimized for the relevant
room by configuring desired airflows while the system is
operating in the min. airflow, occupancy flow and max.
airflow mode. These settings are based on the climate
and energy usage of the room.
• The min. flow is set to the desired airflow when there
is no occupant present in the room. The setting range
is between 0 1/s and at most the value required as the
normal airflow rate when the premises are occupied.
As standard, this value is set to 20% of the occupancy
airflow.
• Set the occupancy airflow to the initial position desirable when an occupant is detected. This flow should be
set to suffice for relatively few persons. As an example, airflow sufficient for 2 persons can be selected in
a room for 10 persons.
• Set the max. permissible airflow to the design airflow
required when the room is full.
The control principle for Application W4 is that if no one
is present, only a small volume of supply air is discharged
so that the air will feel fresh when someone first enters
the room. When the system detects occupancy, the
airflow is increased to the preset occupancy airflow rate.
The CO2 sensor continuously measures the air quality. If
the CO2level remains below the preset max. permissible
value (800 ppm as standard) the airflow will be kept
constant at the occupancy flow setting. If the occupancy
flow is not sufficient for keeping the CO2level below
the max. permissible value, the airflow will be variably
increased and will adjust to the flow that is sufficient for
ensuring the required air quality. Since a conference room
most often is not occupied to capacity, there is seldom
any need for the system to reach the max. permissible
airflow. This control principle makes it possible to save
energy both when the premises are occupied and when
they are unoccupied.
Optional Sequences
Since needs differ from case to case, CONDUCTOR
W4 has been developed with optional cooling step
sequences.
Water first/then air
When the room is occupied, the room temperature is
first regulated mainly by means of waterborne cooling.
If waterborne cooling is not enough, the air volume is
variably increased until the room air reaches the required
room temperature. The air volume is regulated at the
same time according to the CO2 level. If the CO2 level
should exceed the preset max. permissible value, the
controller will increase the airflow regardless of whether
this is needed for regulating the room temperature for
the purpose of ensuring proper air quality. If the required
room temperature is achieved, the waterborne cooling
circuit is closed until a new need for cooling arises.
2015-05-27
www.swegon.com
CONDUCTOR
Air first/then water
When the room is occupied, the room temperature is
first regulated mainly by increasing the airflow. The
airflow is variably increased until the room air reaches
the required room temperature. If the max. permissible
airflow is reached and the room temperature still does not
reach the required level, the waterborne cooling system is
started up in order to increase the cooling capacity. When
the required room temperature is reached, the waterborne cooling system is switched off and the temperature
is again solely controlled by the supply air. The air volume
is regulated at the same time according to the CO2 level.
If the CO2 level should exceed the preset max. permissible
value, the controller will increase the airflow regardless of
whether this is needed for regulating the room temperature for the purpose of ensuring proper air quality.
Manual Control
Although the CONDUCTOR W4 is an intelligent and to
a great extent automatic room control equipment, it is
possible to manually control the room climate. This can be
done by means of the room thermostat which wirelessly
(or via a wired connection) communicates with the controller. The clear display in combination with a clear and
user friendly key pad enables the user to easily change the
room temperature and airflow.
Adaptable commissioning
CONDUCTOR W4 does not require commissioning other
than the setting of a few parameters entered from the
hand-held micro terminal. The adaptive commissioning
feature is made possible by the pressure sensor which is
part of the system. By measuring the static pressure at
appropriate reference points the controller is continuously updated with readings of the current pressure in
the comfort modules and the duct pressure downstream
of the extract air register. Only the transmission of current pressure drop constants via the room thermostat
to the controller is required in order to find out which
airflow is being distributed to the room. The controller
computes which pressure represents the right airflow and
accordingly adjusts the damper blade angle settings until
the correct pressure and thus the airflow to the room is
achieved.
Simplified commissioning is an obvious advantage, but
there are also other benefits. One important benefit is
that possible pressure variations in the duct system will
not affect the preset airflows since the damper blade
angle settings are independent and are only controlled in
response to the values transmitted by the pressure sensors.
Data Communication
The control unit has a built-in communication port that
enables connection to an RS 485 network with Modbus
RTU for supervision and override control via a building
supervision system.

The various operating modes of the controller are shown
in Table 3. The operating modes are based on the status
on the presence sensor, window contact, condensation
sensor and CO2 sensor. According to each operating
mode, the controller controls the airflow, cooling and
heating functions until the user manually sets the temperature and/or the airflow. The controller decreases the airflow when there is no occupant in the room and switches
the temperature control function to the economy mode.
The neutral zone or the dead band in the normal mode,
economy mode and holiday mode can be set by entering
cut-in temperatures for cooling and heating. The setpoint
is set to a lower value (normally 10º C) if the anti-frost
protection function is enabled. When a room is not in
use for a longer period of time, it is possible via a main
control system to continue RE in the Holiday mode.
This is an energy saving operating mode in which the
desired airflow and cut-in temperatures for cooling and
heating can be selected for just this period.
