Technical Description
User Friendliness
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 return air, 5 damper
actuators) and cooling and heating (cooling and heating
circuit, valve actuators)
• 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).
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.

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 occupancy sensor (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
water flow and air flow respectively to a minimum, in
order to save energy.
Timed Airing
When occupancy is detected occupancy sensor (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.
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.
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 (wider dead band), 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 3.6 F, 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.

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.
• 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 50°F.
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.
Energy Saving Control
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.
• The min. flow is set to the desired airflow when there
is no occupant present in the room. The setting range
is between 0 cfm 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.
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.
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.

CONDUCTOR
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.
Air first/then water
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.
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.

CONDUCTOR
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.

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 50º F) if the anti-frost
