IMPORTANT!
Notes concerning alarm systems
Breakdowns, malfunctions or faulty settings may cause substantial damage and financial losses when regulat-
ing and controlling the climate in a livestock house. It is therefore essential to install a separate, independent
alarm system that monitors the house climate concurrently with the climate and production controller. According
to EU-directive No. 98/58/EU, an alarm system must be installed in all mechanically ventilated houses.
We would like to draw your attention to the fact that the product liability clause of general terms and conditions
of sale and delivery specifies that an alarm system must be installed.
In case of an operating error or inappropriate use, ventilation systems can result in production
losses or cause loss of lives among livestock.
We recommend that ventilation systems should be mounted, operated and serviced only by
trained staff and that a separate emergency opening unit and an alarm system be installed as well
as maintained and tested at regular intervals, according to terms and conditions of sale and deliv-
ery.
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.

2 Work Routine
This technical manual deals with the installation of the controller and and is aimed primarily at the technicians
and electricians who will be mounting, installing and testing the controller.
According to current national and in Europe also EU regulations, the installation must be carried out by expert
personnel.
Note that electrical equipment may not be opened without removing the supply voltage, and only competent per-
sonnel may carry out servicing operations and troubleshooting.
The following checklist indicates the main points of the work flow regarding set up of the house controller.
Mounting
1. House controller.
2. Emergency opening, if applicable.
Installation
1. Connect cables according to the circuit diagrams for the emergency opening of the system.
2. Set voltage in the controller.
3. Connect mains voltage to the controller.
4. Select components in the house controller's menu Technical | Installation | Installation wizard by
reviewing all points in the Installation Installation wizard.
5. Connect the individual components by means of the controller's menu Technical | Installation |
Show connections and the circuit diagrams.
6. Customize the controller page views to show precisely those functions and values used in the individual
house.
7. Adjust the system.
8. Test the system.

3 Installation guide
3.1 Selecting Components
There are two ways to carry out installation of the controller.
At the initial installation: Use Installation wizard which will guide you through all the options of the functions.
At adaptation of the existing installation: Use the menu Technical | Manual installation which enables you
to go directly to the relevant function.
Select components in the installation menu of the controller.
( Technical | Installation | Start installation or Manual
installation).
It is not possible to select more components than there is avail-
able I/O for.
You must therefore be aware of whether the controller accepts
your wish to connect a component
If missing I/O, you can:
• install extra I/O modules (if these are available).
• uninstall components.
While functions are selected in the Installation and Show con-
nections setup menus, all alarms will be delayed. Thus, no
alarms will be generated until 2 minutes after the last change in
the installation menu.
This is indicated as info in the alarm menu for as long as the
delay is active.
This does not apply to alarms from CAN bus communication (I/
O modules).
3.2 Slave relays
Using slave relays, the power may be distributed on multiple relays. This is especially useful if the power load is
larger than the max. current of the relays.
For several functions it is possible to select a slave relay which will work in the same way as the master relays -
however, with a delay of up to 1 sec. When the controller is set to Manual, the slave relays will also follow the
master relays.
For heating - when the master is 0-10 V output, the slave relay relay will switch on when the heating is switched
on.
3.3 Setup of operation form

3.4 View week number
View week number View of week number at the top of all pages.
3.5 Select type of Unit of measurements
Unit of measurements The controller can display the units as both metric and US units.
3.6 Connecting Components
The majority of the connection terminals are universal. Different components can therefore be installed using
the individual terminals.
When you select a component from the menu Technical
| Installation | Manual installation the house controller allo-
cates I/O on the basis of a list. This means that the house con-
troller selects the first available I/O on the list, and that the com-
ponents are allocated I/O in the order they are selected.
The same I/O allocation in several controllers – i.e. when the in-
dividual components are connected to the same terminal num-
bers – is ensured by saving the set-up on a USB stick and en-
tering the set-up into several controllers.
3.6.1 Installation wizard
The installation wizard starts automatically when you switch the controller on for the first time. The wizard pro-
vides a structured walk-through of the installation of controller functions. We recommend using the wizard for in-
stallation.
Thus it supports that necessary selections and settings are made in connection with the controller setup.
Choose between:
•Technical | Installation wizard: A complete installation
walk-through.
•Technical | Manual installation: Installation or adaptation of
a specific function, for example, cooling. Here individual
changes can be saved.
Press the arrow buttons in the top right corner to move one step
forwards or backwards in the installation.
Press the X in the upper left corner to terminate the installation
before all steps are completed.
Press Cancel to finish without saving.
Press Confirm to save changes.
Also see section Work Routine for an overview of the complete
procedure for setting up the house controller.
DOL 434 LPV
Technical Manual 11
3.6.2 The menu Show Connection
When you have selected all the components in the installation menu, the house computer will show you where
to connect the individual components.
See the menu Show connection for where exactly to connect the individual components.
When a wiring diagram in the Circuit Diagrams and Cable Plans reads "See Show connection", it refers to this
menu.
3.6.3 Manual I/O allocation
If you want to decide the I/O-allocation for one or more components yourself, you can change it manually under
the menu item Manual I/O allocation.
Select the menu Technical | Installation | Manual I/O
allocation, and press the component to be changed.
Choose between the listed terminals. Please note if a terminal
is currently allocated to another function.
Press the required terminal.
If you use a terminal that is currently used by another function,
the house controller will change the I/O allocation for this func-
tion.
Check in the menu Show connections that the house controller
has moved the first allocated function to another terminal.
The controller will change the I/O allocation instantly.
If the I/O allocation can be changed, the house controller will
accept it.
If the I/O allocation cannot be changed, the house controller will
reject it, and the I/O allocation will remain unchanged.

12 Technical Manual
3.6.4 Shared equipment
Controllers in the same network (see Network settings [}37]) can share equipment such as outside tempera-
ture sensor and outside humidity sensor.
The controller where the equipment is physically connected is called the ‘Master’. The other controllers are
called ‘Clients’.
A climate or production controller may be the’ Master’ of connected equipment while it is also the ‘Client’ of
equipment connected to another controller.
If the connection between the controllers is lost, an alarm appears on both the ‘Master’ and the ‘Client’
controller.
Example of shared outside temperature sensor - setup in ‘Client’ controller
Select the menu Techical | Installation | Manual in-
stallation | Climate | Sensors | Temperature sensor
Activate Use shared outside temperature sensor.
Select the controller where the outside temperature sensor is
connected.
The name of the controller providing the outside temperature is
shown in the display.
3.7 Climate
3.7.1 Air inlets
The house controller includes different types of air intake:
Roof inlet Air inlet in the roof which regulates via a flap, a fan and a recirculation fan.
Side inlet E.g. wall inlets regulated by a winch motor.
A combination of the two types of air inlets allows the possibility to accommodate an increasing need for ventila-
tion by automatic adjustment of the ventilation mode.
DOL 434 LPV
Technical Manual 13
3.7.2 Air outlet
3.7.2.1 Standard settings for stepless fan
The house controller has a range of standard settings for a range of different fan types.
When you choose to load a standard setting, it is not necessary to carry out further settings for fan.
Select the menu Technical | Installation | Manual installation | Climate | Ventilation | Air outlet |
Side outlet | Stepless | Load stepless fan settings.
Select the required fan type.
The setup can be viewed and adjusted in the menu Technical |
Service | Stepless | Adjust stepless. See also the section Ad-
justment of stepless unit [}58].
3.7.2.2 Speed control
3.7.2.2.1 0-10 V speed control
When the fan is controlled by a 0-10 V speed control, voltages must be set corresponding to the fan stopped
and the fan running at full speed. This settings will depend on the type of fan speed controller used.
Select the menu Technical | Installation | Manual installation | Climate | Ventilation | Air outlet|
Select a type of outlet | Fan speed control
Stop fan Voltage at 0 % fan capacity.
Full speed Voltage at 100 % fan capacity.
Note that the factory setting for both menu items is 5.0 V. The house controller will send an alarm if the settings
are not adjusted.
3.7.2.3 Dynamic MultiStep
See section Setting of Exhaustion (MultiStep) for a general description of MultiStep.
Dynamic MultiStep makes it possible to reduce power consumption for the fans in the MultiStep system. This is
achieved by the fans' ability to run at two speeds (Low and High) and by letting them run as long as possible at
low speed.
When a low level of ventilation is needed ventilation is carried out as an ordinary MultiStep system, but the fan
output is limited so that it can only provide a percentage of the fan's maximum capacity.
All exhaust units that are set up to run only in the low area in the Dynamic MultiStep system must be able to run
at reduced capacity.
When a high degree of ventilation is required, the fan output varies steplessly from low to full speed and the
flaps are fully open.
DOL 434 LPV
14 Technical Manual
0-10 volt output
The 0-10 V output makes it possible to run at low speeds on the
fan, and from here to run the fan steplessly up to full speed.
Low speed and Full speed
When a fan connect to a 0-10 V output has been selected, a
voltage value must be set which corresponds to the fan running
at low and full speed.
Please note that most fan types have stopped at 10 volt.
Depending on which type of fan has been selected, the voltage
is set at low speed to 4-6 volts.
For each MultiStep unit, set whether it should be activated
when the Dynamic MultiStep system runs at high speed, at low
speed or with both.

3.7.2.4 Parking of fans
With this function, fans can be taken temporarily out of service. This can, for example, be used in cold periods
where some fans are closed for insulation purposes, or if a fan is defective and awaiting repair.
DOL 434 LPV
Technical Manual 17
The function is available in the LPV and CT variants and for all type of ON/OFF MultiStep.
We recommend that you use parking of fans which are not in use as this will enable the ventilation regulation to
automatically adapt to the altered ventilation capacity.
Please not that if a MultiStep is set up to be active in case of failure, the controller will try to start it in case of
failure no matter if it is parked. See also the section Active Functions in the Event of Control Failure [}18].
3.7.3 Setup of minimum ventilation
| Technical | Installation | Manual installation | Climate | Ventilation
Minimum ventilation Setting up whether Minimum ventilation shall be shown either as a percentage of
the nominal ventilation rate or as m3/h per animal (real air).
3.7.4 Heating
Room heating can be regulated as common or individual heating, depending on the number of temperature sen-
sors (not for Heat controlled by own sensor).
Common regulation: A sensor combination with a common setpoint for all room heaters
Individual regulation: A sensor combination for each room heater.
Heat control
(only house heaters)
Choose whether heat sources 1 and 2 should start in parallel or sequentially.
Heat distribution Distribution of capacity between heat sources 1 and 2 (for separate heat control only)
Sequential heating is typically used when there are two different heat sources in the
house.
For example:
• heating pipes and air heaters
• heating pipes and blow heater as extra capacity
It is important to distribute correctly between the two types of heat sources, in order to
obtain a steady heat control. The heating system’s dimensions and output determine the
actual distribution.
3.7.5 Setup of sensors
Temperature sensor se-
lection
Location of temperature sensors for ventilation and heat control.
You can set up several temperature sensors in the livestock house to register the
temperature in each zone.
Number of auxiliary sen-
sors
Select a number of auxiliary sensors.
Auxiliary sensor setup Select the required type of auxiliary sensor.
Name the auxiliary sensor according to function to make it recognizable in alarms
and other info.

3.7.6 Active Functions in the Event of Control Failure
When installing MultiStep air outlet and side cooling, you must decide how these functions is to react in an
emergency situation.
MultiStep air outlet
Activated: When the control fails, the air outlet is active.
Deactivated: When the control fails, the air outlet is inactive.
3.7.7 Setting of side cooling
Cooling mode If there are more cooling pumps, they can be set to running either sequentially or in
parallel.
Side cooling relay ratio Side cooling features up to three relays.
The percentage share between cooling relays that are controlled sequentially.
E.g. with two relays: 50 %/50 %
The controller automatically calculates the percentage share for relay 1.
Side cooling
Activated: When the control fails, side cooling is active and runs
until the emergency situation is over.
Deactivated: When the control fails, the side cooling is not ac-
tive.
Note that in an emergency situation the house controller cannot regulate according to temperature and
humidity. If you select Yes (Active at failure), side cooling runs no matter whether the temperature is too
low and humidity is too high in the house.
Note also that a combination of a high inside temperature and high air humidity can be life-threatening to
the animals.
3.7.8 Stir fan
Stir fans are typically used to improve air circulation inside the house and thus provide a more uniform tempera-
ture in the house. This may be relevant in house where one end of the house is exposed to wind or maybe is
more leaky (for example at doors or gable fans). Stir fans may run here when a too high temperature difference
is measured in the areas. They may also run constantly or via a timer to ensure good heat distribution in periods
where heat is added to the house.
DOL 434 LPV
Technical Manual 19
Depending on the type, location and connection method, however, a stir fan can be used for many different pur-
poses.
A stir fan can be connected with relay, 0-10 V, 0-10 with reverse and with slave relay.
Each stir fan can be named for recognition in menus, activity log, and overview.
3.7.8.1 Control methods for stir fan

Control method: temperature.
The stir fan is regulated with a minimum and a maximum speed based on a positive temperature offset at the
temperature sensor.
0-10 V with reverse relay
Control method: temperature.
The stir fan is regulated with a minimum and a maximum speed based on a positive temperature offset at the
temperature sensor.
Also the direction of rotation of the stir fan can be reversed. Thus, it will be running at minimum speed based on
a negative temperature offset at the temperature sensor.
See elaborate descriptions of the control methods in the climate controller’s User Manual.
3.7.8.2 Wind protection of stir fan
When using a weather station the house controller can turn off the individual stir fan if e.g., there is strong wind
from a specific side. The function is mainly intended for the protection of big stir fans that can be very sensitive
to wind. It will as well contribute to energy savings as the stir fans are stopped when the exchange of air is
maintained by the natural air circulation.
Natural system selec-
tions
Select which natural air inlet systems should use wind protection for the individual
stir fan.
When the weather conditions exceeds the allowed limits the stir fan stops if the air
inlet system is open.
The limits for wind velocity and wind direction is set in the menu Climate | Stir fan | Wind protection | Stir fan
limitations. See the section on Wind protection in the user manual.

3.8.1 Light control
The main light can be fitted with a light dimmer.
The light control consists of two different types of light: main light and inspection light.
Light dimmers with relays are used in houses, where the light source used cannot be switched off by means of
the dimmer alone.
Light control
Main light Setting the main light with or without dimmer, with or without relay.
DOL 434 LPV
20 Technical Manual
Number of light sensors Setting the number of light sensors.
Light control settings
Light sensor settings Selecting light sensor type.
Main light This is used to name a light source according to function, so that it can be recog-
nized in the menus and alarms.
Light intensity unit Lux or percentage.
Light sensor controlled
Use boost This is used for light fixtures that cannot be switched on unless they start at maxi-
mum power for a short period of time.
Max. light intensity Setting how wide a scale you should be able to adjust the light within. This en-
ables you to adapt the light control to the type of light source used in the house.
The scale can be set from 1-1000 lux and the factory setting is 100 lux.
Inspection light Setting up if inspection light is available or not.
Inspection light settings Duration: Setting an active period and light sources for the inspection light.
Active: Activation or deactivation of inspection light.
Light intensity: When a light source has been installed with a light dimmer, a re-
quired light intensity (lux) for the inspection light can also be set.
Light dimmer boost time Setting the duration of the boost when the light is turned on.
When light has been installed with a light dimmer, it can turn on using a so-called
boost. It means that it turns on with the maximum intensity and that it then adjusts
according to the setting.
Light active at failure Setting if the light should switch on at power failure.
When installing light you must decide how the function is to re-
act in an emergency situation.
Yes: In case of control failure, the light is on.
No: In case of control failure, the light is off.
3.8.1.1 Light sensor
When using a light dimmer, the light can be controlled by a sen-
sor.
The light sensor is also used for alarming purposes.
Select which sensor type to use.
If Other Sensor is selected, it must be calibrated.
3.8.2 Water
Number of water meters Setting the number of water meters.
Liters pr. pulse Setting the number of liters that runs through the water meter for every pulse.
