CONDUCTOR is a control system for the individual control of room
temperature and airflow, especially adapted for partitioned offices and
hotel rooms. It can operate independently or in combination with a central
system.
Controller and Room Unit (thermostat)
The main components in the CONDUCTOR W4 control system are a
controller and a room unit (thermostat).

Technical Description
The controller is equipped with inputs for connection of a condensation
sensor, carbon dioxide sensor, window switch, presence detector and
outputs for the connection of actuators for valves and air dampers.
Up to twelve pairs of actuators (twelve for cooling + twelve for heating) can
be wired to each controller. Or you can connect 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).
The controller provides proportional and integral (PI) control. Through
so-called PWM control (pulse width modulation), the I section senses both
the size and the duration of the control deviation and adjusts the actuator
opening time accordingly. It is possible to switch over from PWM control to
0-10 V control, if needed.
The user can easily configure the controller functions and parameters by
means of the room unit (thermostat).
The controller has a built-in communication port that enables connection to
an RS 485 network with ModBus RTU for supervising and override control
via a main control system.
Product Identification Label
The product identification label affixed to the front of the controller,
indicates rated data, the controller ID-number, which you will need when
you install the CONDUCTOR.

The sequence involves the following: If occupancy is registered in the room
and if the temperature is at a certain level, the system starts a cooling
process that cools down the room by increasing the airflow.
If the temperature rises more and the increased airflow is not sufficient for
maintaining the required temperature, the cooling process is supplemented
with cooling by circulating chilled water in the water pipes.
If the level of carbon dioxide in the room exceeds a certain level, the air
system is activated in order to reduce the level and keep it constant.

Operating Mode
Depending on the status of connected sensors, the controller adjusts the
outputs from any of several possible operating conditions.
The various operating conditions described here are based on occupancy
in the room and the status of the window contact, condensation sensor,
carbon dioxide sensor and the current pressure.

Technical Description
Operating Modes
There are a variety of functions built into the CONDUCTOR:
• MAN, manual mode.
• AUTO, automatic mode.
• ECON, energy-saving mode.
• Stand-by mode.
• EMERG, emergency mode.
MAN, Manual operating mode.
Whenever the CONDUCTOR registers occupancy in the room in response
to signals from a presence detector, the user can regulate the temperature
and airflow rate by entering settings in the room unit. When the user enters
a new desired setting, the controller switches over to the manual operating
mode (MAN).
AUTO, Automatic operating mode.
When the CONDUCTOR no longer registers occupancy in the room, the
controller automatically decreases the supply air flow to the low airflow
setting and the system automatically returns to the AUTO mode.
The controller also switches automatically to the AUTO mode after a
predefined number of minutes after the most recent change, manually
entered on the room unit.
When the controller is set to the automatic mode, the valve actuators for
chilled water and hot water respectively and the supply air damper and
extract air damper respectively are adjusted in response to occupancy in the
room and the level of carbon dioxide as well as the status of the window
contact and the condensation sensor.
The automatic control system controls the airflow, cooling and heating until
the user manually enters a new airflow or temperature setting.
ECON, energy-saving mode.
When the energy-saving function is enabled, the system switches
automatically to the ECON energy-saving mode, when no occupancy has
been registered for a predefined number of minutes. The system returns to
the AUTO mode when occupancy is registered again.
In the energy-save mode, the valve actuator is controlled for chilled water
and hot water respectively according to the status on other sensors in the
room, but with a greater permissible difference between actual value and
setpoint than in the AUTO mode.
2 : 13
Technical Description
Stand-by mode.
When the control system registers a signal indicating that a window is open,
the controller switches over to the standby mode. When the window is
closed, the controller switches to the AUTO operating mode.
While the controller is in the Stand-by mode, the room temperature is
maintained above the predefined level for the Frost protection function.
EMERG, emergency mode.
In the event of a fire alarm, the air damper in the extract air duct is opened
or closed, depending on the setting entered in the control system. The
cooling and heating functions are shut off while the system is in the EMERG
mode. The supply air is normally shut off.
The EMERG mode can only be managed in control systems that are
connected to a main control system via ModBus RTU.
Functions
There are a variety of functions built into the CONDUCTOR W4:
• Exercising of valves
• First open
• Frost protection
• Change over
• Night cool
• Time-set setpoint restoration
Exercising of valves
The function involves regularly exercising the water valves by utilising
automated functions in order to prevent them from becoming sluggish or
jamming. During the exercising period, all the valves that are wired to the
controller are opened for a maximum of 6 minutes and are then closed.
The valves for the cooling system are exercised first. Then the valves for the
heating system are exercised.
First open
The function means that the water valves are open when the system is
installed, which makes it easier to fill, pressure test and vent the water
system.
The function will be automatically disabled after the actuator has been
energized for approx. 6 minutes. A clicking noise will be heard when the
valves and the dampers change over to the NC mode (=normally closed)
and the normal control function is enabled.
2 : 14
Technical Description
Frost protection
The function involves the following: Heating operation is started at a
predefined room temperature in order to counteract the risk of damage that
otherwise can arise due to freezing.
Change over
The function involves the use of only one valve actuator. This valve actuator
then controls both the heating water and the cooling water, which are
transported in the same pipe.
In the wintertime, when heating is required, the valve opens if the water in
the pipe is hotter than the temperature setpoint. If the water is colder, the
valve is not opened.
In the summer, when cooling is required, the valve opens if the water in the
pipe is colder than the temperature setpoint.
An external temperature sensor must be mounted on the water pipe with
continuous inlet water circulation in order to be able to use the function.
Night cool
The function involves using cold air from outdoors for cooling the room at
night to the predefined level.
The function can only be managed in control systems that are connected to
a main control system via ModBus RTU.
Time-set setpoint restoration
The function involves adjusting the room temperature to the predefined
level when the controller switches to the AUTO operating mode.
The controller also switches automatically to the AUTO mode after a
predefined number of minutes after the most recent change, manually
entered on the room unit.
2 : 15
Technical Description
C-Factor and Offset
C-Factor
The controller calculates how the air dampers should open and close in
order to achieve the required airflow.
A so-called C-factor, which is a value for resistance, is used in the
calculation. Utilizing the C-factor and the pressure in each air duct, the
controller calculates the flow in the air duct.
Offset
A balanced pressure, a positive pressure or a negative pressure can be
created in order to provide satisfactory ventilation in the room. Using a socalled Offset value, the controller carries out a calculation in order to achieve
the required pressure in the room.
Pressure = SA1 + SA2 + Offset
The value 0 for Offset gives rise to a balanced pressure. A negative value for
Offset gives rise to a positive pressure whereas a positive value gives rise to
a negative pressure.
• Balanced pressure = Just as much supply air as extract air.
• Negative pressure = More extract air than supply air.
• Negative pressure = Less extract air than supply air.

Trouble shooting
An alarm is initiated when an error arises in the control system. There are
two types of alarms:
• General alarms.
• Application alarms.
Trouble shooting of the control system should always begin with
investigating whether any alarm has been initiated and if so which.
Certain alarms are automatically reset (Auto) after the cause of the error has
been remedied, while other alarms have to be manually (Man) reset.
If the control system is connected to a ModBus system, the alarms can be
read within the 10100 – 10139 range.
