Controller installation
Warning! While installing the device it must be cut off from any power supply, because the
voltage on some of the components is highly hazardous to your health and life. It is advised
to entrust a qualified and skilled personnel to carry out this installation.
Choosing a place for the installation
The place for the installation have to be chosen rationally, taking into account easy access to such
device for the persons concerned, and at the same time having a spot inaccessible for children or
animals. Climate conditions should be also concerned, which means that the device ought to work within
the temperature range from -10°C to 40 °C, in a place not exposed to direct sunlight. Free air flow
around the device is also essential. The temperature sensor is an integral part of the device. There are a
few rules to be followed in order to install such sensor:
•the sensor should not be installed in a place with no free air flow, or in a spot directly exposed to
sunlight
•the sensor should not be installed on the load-bearing wall of the building
•presence of nearby heat-emitting devices such as radiators or lamps should be avoided
•the sensor should not be placed directly by the door or ventilation holes
•the sensor should not be placed in spots accessible for animals
•it is advised to arrange the wire connected to the sensor away from the power cords
The installation
The device works in rough climate conditions. If properly installed, the controller and the sensor are both
resistant to the harmful influence of the environment.
Bear in mind the following comments while installing the device:
•the cover gasket should be checked before screwing
•the cover should be fully tightened by all the screws
•the wires used to connect the sensor should be round
•after connecting a wire, the cable gland should be tightened up in such a way to seal and
immobilize the wire, the use of silicone is advised
•unused cable glands should be closed (sealed)
•the controller (from its bottom part) should be attached on a flat wall using four rawlplugs
Plugging in
Warning! Be sure that the power supply is cut off before you plug in the device!
Before connecting the controller for the first time, the front panel should be unscrewed and then
removed. Depending on the work mode, the adequate number of holes for the cable glands should be
made (cut out from the bottom part). The wires should be inserted into the rubber cable glands and then
connected. The illustration below presents the arrangement of the connectors of this device.

SPEED CONTROL-12 v2a Instruction Manual
Connector labelled as AC 230V should be connected to the power supply (switching station). Using the
circuit breaker 1P-B6 and overvoltage limiters of T1 and T2 type is obligatory. It is worth grouping the
controllers on different phases (L1,L2,L ) while connecting multiple devices, in order to equally load the
power line.
Connector labelled as FAN should be directly connected to the ventilator. In case of controlling multiple
ventilators the aggregated load cannot be higher than 12A. Every ventilator should be separately
secured. PE and N outputs should not be guided from the power supply (the switching station). Instead,
they ought to be connected to the connectors of the controller.
Connector labelled as FAN 2 may be used for connecting 2nd stage ventilators or the spraying systems.
The output is separated with max relay current of 6A (the circuit breaker 1P-B6 is required, when
controlling the load directly). The relay activates when the measured temperature is higher than the total
amount of value set previously by the user and the band ventilation value.
Connector labelled as HOT may be used to connect the heater. The output is separated with max relay
current of 6A (the circuit breaker 1P-B6 is required, when controlling the load directly). The relay
activates when the temperature drops below the value set by the user.
Connector labelled as ALARM – NC,C and NO outputs that should be connected to the alarm control
panel. The alarm activates automatically when:
•the temperature is too low or too high,
•the controller or the temperature sensor is damaged,
•the power blackout occurs,
•the controller malfunction occurs (e.g the device is overheated)
Connectors labelled as FUNC1 and FUNC2 help to connect the elevator to opening the air inlets using
the left/right motor. FUNC1 relay provides current for the servo motor, while FUNC2 relay switches the
direction of the motor rotation. The exemplary scheme of connecting the elevator is presented below -
(the circuit breaker 1P-B6 is required).
By deactivating the elevator function, FUNC1 and FUNC2 outputs work respectively as the relays of the
rd and 4th stage ventilation.

Connector labelled as 12V is intended to provide power for the external sensors.
Connector labelled as V1 0-10V is intended to connect the expansion modules. The voltage on this
connector is proportional to the level of ventilation.
Connector labelled as V2 0-10V is intended to connect the servo motor that opens the inlet flaps.
Connector labelled as V3 0-10V is intended to connect the smooth speed heating system. The voltage
of this output increases proportionally to the decrease in the temperature, starting from the heating temp.
value.
Connector labelled as 10V is intended to power the potentiometer of the elevator, or other 0-10V type
components.
Connector labelled as SENS1 (SENS2) should be connected to one TS- or TS-5 temperature sensor,
the polarity is not relevant. If connecting two sensors at the same time, the temperature measured
values are averaged. It is advised to arrange the test leads away from the power cords.
Connector labelled as 1-WIRE may be used to connect higher number of the digital temperature
sensors to the maximum of 4, connected in parallel (with the appropriate polarisation maintained). The
maximum length of the wire connecting the sensors is 150 m (the length of the wire has no influence on
the temperature measurement). Using the screened cable is advised.
Connector labelled as RS-485 may be used to build ventilation systems and for the PC communication.
Connector labelled as IN1 0-10 is intended to implement the feedback signal to the air inlets -
determining current inlets position.
Connector labelled as IN2 0-10 is intended to connect the controller with other sensors, e.g. the humidity
or CO2 sensors or the sensor working as the power extending module.
Working principle
The primary function of the controller is to maintain the temperature in the breeding room at the level set
by the breeder. Please note that the controller is only a tool that helps to provide the optimal climate
conditions in the room. The breeder plays the main role in the whole process by adjusting the settings on
the device based on current weather conditions outside the building, as well as (and most importantly)
based on the observation of the behaviour of all animals. The user should also monitor the device work
status using the alarm control panel.
First controller start-up
aution! While starting the sensor up for the first time the settings of the minimal
fan speed must be adjusted immediately.
The sensor cooperates with the ventilators equipped with the single-phase induction motor, capacitor
start-up and the maximum current consumption of 12A. After the attachment of a given ventilator, the
user has to adapt it to the cooperation with the controller. In other words, it is necessary to set the
minimal fan speed. Such function is similarly called “Minimal speed” and it can be set after entering
ELETOR ELETOR, Zbiczno 4 D, 87- 05 Zbiczno, Poland tel. [phone]
www.eletor.pl | email:[e-mail]

SPEED CONTROL-12 v2a Instruction Manual
“Advanced setup” option. To perform such action properly, it is advised to cooperate with another person,
who can set the value of “Minimal speed” (the default value is 0μs). Not having this setting adjusted, the
device may not work properly.
The value of “Minimal speed” may be considered as valid ,as soon as the flaps of the ventilation stack
start to lift slightly.
If a new ventilator is being attached to the controller, the whole activity of setting the “Minimal speed” has
to be repeated.
Periodical airing
Airing is one of the functions performed by the controller, which activates when the temperature in the
room drops below the temperature value set by the user. Such function guarantees a constant air
circulation inside the breeding room to provide a regular air supply for the animals, at the same time
extracting already used air. There are three parameters available in the airing mode:
•“Time airing” - indicates the time duration of the activated ventilator (in minutes)
•“Break time” - determines the amount of time during which the ventilator is not working
•“Airing level” - indicates the power value of the ventilator in “Time airing”
All of the parameters above can be set by the user. However, there are some rules to be remembered
while adjusting the values in the airing process:
•airing is turned on only when the temperature in the piggery drops below the value previously set
by the user,
•the primary function of airing is to provide a constant fresh air supply for the animals, and not
maintaining the temperature that had been set in the room,
•airing the room frequently for short periods is strongly recommended,
•longer airing periods should be avoided, because they can lead to major temperature variations,
•the parameters must be adjusted properly according to the behaviour of animals in the breeding
room and all the conditions that occur not only inside, but also outside of the building.
Device working scheme
The controller smoothly regulates the ventilation
from “Min 1” to “Max1” within the range of
“Setting temp.” and “Airing band 1”. “Vent 2nd
stage” will be active above that range and “Level
min. 1” will immediately change to “Level min. 2”.
As the temperature continues to grow, it will
change to “Level max. 2” at the end of “Airing
band 2” range. If “Airing band 2: equals “0”, but
“Level max.1” is enabled, “Vent. 2nd stage” will be
activated, causing further increases in the
temperature to have no effect on changes in the
ventilation process (dotted part of the graph). In
the case of the temperature in the room dropping
below the “Setting temp.”, the controller turns on
the airing process periodically and if it continues to drop, heating is additionally activated. Every action is
based on the adjustments that the user had implemented before. When the temperature in the piggery
has different parameters than those set by the user, the programme of the controller may connect with
the alarm control panel and activate the alarm.
