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

The function of the room unit is to measure the temperature in the room,
communicate with the controller and to serve as a tool for adjusting the
climate in the room.
The internal communication between the controller and the room unit is
wireless, which makes it easier to find an appropriate spot in the room
where the room unit can be installed.
If requested, the room unit can be wire-connected with a RJ12 cable to the
controller.

Operating Mode
Applications
These instructions deal with two different applications: W1 and W3. W
indicates that both the applications are applicable to waterborne climate
systems.
A waterborne system provides the room with waterborne heating and
cooling. The air-based systems which can be controlled in the W3 by means
of connected damper actuators are only used to satisfy the demands on
air quality, while the temperature of the supply air and extract air is kept
constant.
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 switch and condensation sensor.
W1
Technical Description
W1 is a standard solution for offi ces, mainly designed for partitioned offi
ces, but which also can be used in large rooms, as with open-plan offi ces.
The application is suitable for so called CAV systems (Constant Air Volume),
which means that the airfl ow in the room is constant and that no damper
actuators are needed. Only two outputs are used, one for actuators that
control cooling and one for actuators that control heating. There is provision
for connecting a condensation sensor, a temperature sensor and an
presence detection sensor.

Technical Description
W3
The W3-application can be used either for offi ces or for hotel rooms. It is
well-suited for systems with variable airfl ow (VAV) with both supply air and
extract air. Four outputs are used to control heating, cooling, supply and
extract air. The damper motors are adjusted depending on the generated
airfl ow and duct pressure in both the supply and extract air ducts.
Three inputs are used; for condensation sensors, window switches and
presence detectors. The principle is to use minimal, normal or high airfl ow,
depending on occupancy and sensor status.

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.
Technical Description
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 W1/W3:
• 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 which should be
wired to the cooling output terminal. This actuator then controls both the
heating water and the cooling water, which are transported in the same
pipe.
In winter, when heating is required, the valve opens if the water in the pipe
is warmer than the temperature setpoint. If the water is colder, the valve
does not open.
In summer, when cooling is required, the valve opens if the water in the pipe
is colder than the temperature setpoint.
In order to be able to use this function, you are required to mount an
external temperature sensor onto the water pipe through which supply
water circulates continuously. Wire the sensor according to the general
wiring diagram shown in the section entitled: Installation
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.
