Manual
The instruction manual for the device is constantly updated. Changes to the manual may occur depending on the software
version of your device. On the web, you will always find a user manual that matches the latest software version. If your device
is connected to an Internet network, you always have the latest software version.
Starting the device
The first time you connect the device to the mains, the device immediately starts working (manual mode, speed 5).
Each time the device is connected to the mains, the device checks the operation of all sensors and functions. The device can
carry out the calibration of the fans, momentarily putting them to work at maximum speed. The maximum duration of actions is
3 minutes. After the actions, the device will continue its normal operation. When the supply current is interrupted and restored,
the device repeats the previous actions. The settings entered by the user are stored in memory, and the device continues to
work with the previous settings.
Pause or turn off the device
There are two ways to stop ventilation:
1. From the control unit or the mobile application, switch the device to MANUAL mode and set the fans to 0.
2. In the control unit or mobile application, select the "Turn off" function. In the off state, the device is in standby mode.
Steps to turn off the device:
● Stop the operation of the ventilation unit by selecting the "Turn off" function in the control unit or mobile application.
● Unplug the device's power cable from the electrical network.
It is not recommended to stop or turn off the device even if you plan to stay away for a longer period of time. If there is a
possibility that condensate water may be present in the appliance or heat exchanger, the device must not be stopped for a
period longer than a day, otherwise stagnant water may damage the heat exchanger. If it is necessary to stop the device for a
longer period, the heat exchanger must be removed and dried.
During maintenance, replacement of filters or other operations related to the device, the device must be removed from the
electrical network!

Control unit VE1 (new from 11.2022)
The VE1 control unit is only compatible with devices manufactured from 07.2021 (V02.. starting serial code on the device). If
the device is older than the one produced in 2023, then it may also be necessary to update the software of the device,
otherwise the remote control will give an error message that it cannot connect to the device. To update the software, connect
the device to the Internet, and this is done instantly automatically.
*CO2 level and air quality readings are only for controllers with a CO2 sensor integrated (in the model designation -AQ).
The air quality assessment gives a score on the overall exhaust air quality on a scale from 1 to 5, where 5 is very good and 1 is
very bad. The air quality score is mainly based on the level of CO2.
The origin of the air parameters can be two: Extract Air / Exhaust Air and Controller / Control Unit. This refers to the air from
which the temperature, humidity and CO2 level are displayed. For example, a control unit can be installed in the living space,
which then allows you to measure the air quality and control it according to a particular room. In the case of exhaust air,
readings are measured from the exhaust duct of the ventilation unit.

Modes of operation
Automatic mode
The purpose of the automatic mode is to monitor the quality of the indoor climate and react to various events by reducing or
increasing the rate of ventilation and thereby trying to improve the air quality within the limits of its capabilities or saving
electricity.
In automatic mode, you can enter the upper setting point to the level of humidity and CO2. If any of these indicators exceed
the desired setting point, the device will attempt to bring these levels down to the best of its ability by adjusting the fan speed.
Setting the minimum and maximum operating speeds for automatic mode
The minimum air flow rate setting determines the speed at which the device ventilates if the humidity and CO2 levels are not
above the setting point and there are no air quality events.
The maximum airflow rate is the maximum permissible ventilation level if any of the actual air quality values are above the
setting point or if there have been air quality change events.

These settings can be selected according to preferences or preferably according to the requirements of the air flow to be
designed.

Summer bypass open minimum operating speed
In the summer period, there may be a desire to ventilate at a higher operating speed in the event that the outside air is cooler
than the air in the room and there is a desire to get more ambient air into the rooms. The device switches to the selected speed
as soon as the bypass valve opens.

Automatic moisture detection mode
The device can detect a sharp increase in air humidity. If the air humidity rises sharply in a short period, then the device
switches to the selected speed in order to drain the resulting moisture. This mode is usually activated when a shower or sauna
room is used. The duration is a minimum of 15 minutes or up to 2 hours depending on how quickly the previous humidity level
is reached.

Mobile app

On-premises detection and energy-saving mode
The energy-saving mode is activated when the device detects that no one is indoors using data from different air parameters (in
general, if the CO2 level < 550PPM and there are no air quality events). The goal of the energy-saving mode is to reduce the
power consumption of the device, and this can be especially useful during the winter period – the lower the air flow rate, the
less energy is spent on frost protection. It is important to note that this function may not always work as expected since it
depends a lot on the average CO2 content in the air that reaches the device over the entire ventilated surface: it ultimately
depends on the number of inhabitants and the size of the ventilated surface. In the case of buildings over 250m2, you should
think about thermostats with CO2 measurement.
The device switches to the minimum possible speed, i.e. 1. The mode will come in handy when the minimum speed of
operation in automatic mode is set, for example, 3. If no one is in the rooms, it is not necessary to ventilate at a speed of 3 and
the device automatically switches to the minimum speed (speed 1). There are three modes to choose from.
• AUTO (default) – The device automatically detects the summer period, and during this period the power saving mode
is turned off. It is often necessary to ventilate more during the summer period even if no one is in the rooms.
• ON / On – The power saving mode is activated regardless of the period.
• OFF – Power saving mode is turned off and not activated.

Boost mode
In boost mode, temporarily switches the setting to maximum speed (10), and after a while switches the device back to the
previous (automatic or manual) mode. The duration of the mode depends on the choice made during activation: from 30
minutes to 6 hours
Overpressure mode (fireplace mode)
The overpressure mode creates a temporary overpressure in the room by reducing the exhaust fan speed relative to the supply
fan and switching back to the previous (automatic or manual) mode after a certain time. The duration of the mode depends on
the choice made during activation: from 30 minutes to 6 hours. The operating speed depends on the setting, which can only be
set in the mobile application "Settings - Overpressure mode air flow rate".
Air quality and sensors in the device
Carbon dioxide (CO2) sensor
Indoor air quality is assessed primarily on the basis of the level of carbon dioxide or CO2. In living quarters, the main sources of
CO2 are the person himself and the burning of gas (gas stove) or wood (fireplace, oven). It is about 4% in the air exhaled by a
person, 0.03-0.04% in the ambient air, so there is about 100 times more of it in the indoor air than in the outdoor air.
Various studies also confirm that it is CO2 that is most often a reflection of human well-being. It depends on how well you sleep,
how rested you are when you wake up in the morning, how energetic you feel and how busy you are during the day. The high
amount of CO2 in the surrounding air makes it difficult to concentrate and work, due to which work performance decreases. In
addition, the concentration of CO2 is associated with the spread of viruses - a high level of CO2 suggests that this is a poorly
ventilated room, and in this room there are a lot of particles exhaled by people.
The amount of CO2 in the air is expressed as a unit denoted by ppm (parts per million). That is, how many particles of the test
substance are in the considered unit of space per million particles. The level of CO2 in the air can be estimated and measured
as follows: the starting value is considered to be 400, which is the concentration of CO2 in clean ambient air, green or good is
between 400 and 800 ppm; yellow or average between 1000 and 1600 ppm, red or bad if it is more than 1600 ppm and this is
the limit from which air quality has a negative impact on a person.
Principle of operation: Airobot ventilation units measure the level of CO2 through the exhaust pipe - the sensor is located
inside the device. Thus, the averaged value of all rooms reaches the device by a few - the larger the size of the ventilated room,
the more inaccurate the value shown by the device may be relative to a particular room. The biggest advantage of an in-device
CO2 sensor is that the device has the ability to assess the presence in the premises in cooperation with other sensors.
Airobot's unique on-premises detection feature is one that can reduce your device's power consumption (especially during
winter periods) by ~30% (compared to conventional ventilation equipment, the exact energy saving rate depends on the actual
use and varies).
When working in the automatic mode of the ventilation unit, the user can choose a suitable CO2 limit, above which the
ventilation rate is increased. Depending on the season, it may be necessary to adjust this limit, as the CO2 sensor constantly
calibrates itself.
CO2 and air quality scale considering Airobot ventilation unit
*The air obot ventilation unit analyzes the exhaust air so the scale may vary depending on the size of the ventilated rooms, the
calibration of the sensor and the season.
Automatic calibration: All CO2 sensors (including the Airobot sensor) need constant re-calibration. Re-calibration of easy-to-
use CO2 sensors is carried out automatically and does not require user intervention. The automatic self-calibration algorithm
assumes that the sensor is exposed at least once a week to a clean air CO2 concentration of 400 ppm, which is considered to
be clean ambient air. In the case of rooms, it is assumed that at least once a week the rooms should be completely empty for
half a day, so that the CO2 concentration can go close to the outside air, and then the sensor can use it as a new starting
value. Thus, for example, during summer periods, when windows are often kept open, the CO2 sensor reading may be
completely different from that of the winter period, since the rooms have a persistently low concentration of CO2 and the
sensitivity of the sensor has changed. Sometimes, rarely, the sensor calibration can also go out of place, in which case a new
calibration of the sensor can be done manually by contacting the helpdesk.

Volatile organic compunds (VOC) sensor
Volatile Organic Compound (VOC) are organic compounds that are considered to be the main polluters of indoor and outdoor
air. VOCs come from many different sources, such as building and interior materials, chemicals used in everyday items,
cleaning products, paints, dust, vapors, perfumes. High VOC content is usually found in newly built or newly renovated
buildings. VOCs directly affect human health and cause dryness and irritation of the eyes, nose and throat, headache and
dizziness.
The VOC algorithm of the Airobot ventilation unit analyzes the VOC events detected by the sensor and maps them to a VOC
index on a scale of 0-500. The VOC index shows the extent to which indoor air quality has deteriorated or improved, with the
main purpose of the sensor being precisely to highlight VOC events and momentary polluters – for example, when using
perfumes, cleaning agents, alcohol-containing chemicals or the like in rooms, the VOC reading generally increases, which
indicates that a source of pollution has been identified in the rooms.
VOC index scale on Airobot ventilation unit and air quality relationship:
Index 100 is the silent value of the VOC content. If the sensor reading drops below 100, this indicates that the number of VOC
particles has decreased compared to the previous 24H period. If it rises, then indicates that the number of VOC particles has
increased compared to the previous 24H period.
Principle of operation: At the moment, the Airobot ventilation unit does not increase the ventilation speed by detecting VOC
events. As part of the software update, this functionality is coming soon. Sensor readings are displayed in the mobile
application or on the control unit. When the device starts up again, the sensor heats up for 1h and only then begins to display
readings.
The VOC sensor is integrated into devices with SN/ID code starting from V02XXXXXX (produced from 07.2021).
Features
Automatic bypass valve (summer cooling)
Airobot ventilation units are equipped with a fully automatic summer bypass valve. The idea of a bypass valve is that during the
summer period it would be possible to partially (V3, L5, V8, L models) or completely (100% S1,S2 models) stop heat recovery
and direct the air coming from the outside partially or completely past the heat exchanger directly into the room. It is important
to know that the ventilation unit is not a cooling device, and this function allows you to blow somewhat cooler outside air into the
room on hot summer nights, but this does not always bring down the temperature inside the rooms.
The bypass has two modes:
● OFF / Off – always closed. The bypass flap is never opened.
● AUTO – the opening / closing of the bypass valve is carried out automatically according to the following conditions -
all conditions must be met for a minimum of 15 minutes:
○ The ambient (or supply air) temperature is higher than 13°C. A lower temperature is not allowed, since
otherwise condensate water may form on the surface of the pipeline, which, in turn, can damage the
structures of the building.
○ The air temperature of the outside air is lower than the exhaust air temperature – if it is warmer outside
than in the room, the heat recovery is reversed, i.e. the cooler air in the room is used to cool the warmer air
coming from outside.
The position of the valve from the moment can be checked from the INFO menu on the control unit or in the mobile application

• CLOSED / Closed – the bypass is currently closed and heat exchange is taking place.
Pre-heating and frost protection
If the ambient air drops to minus degrees, under certain conditions, the heat exchanger may freeze. To avoid this, electric pre-
heating is integrated into the unit, which ensures that the air entering the device from the outside is at least 0°C to -3°C. The
exact freezing limit is calculated by the device itself taking into account various parameters (air volume, air humidity, air
temperature). In the case of a heat exchanger with moisture recovery, the limit is from -5 °C to -7 °C. The control of the heating
element is carried out on a demand-driven basis. The device generally operates without an air volume limit up to -20 °C outside
air temperature (may vary depending on the conditions and the amount of airflow), then the device can gradually limit the
amount of air and, if necessary, remain temporarily stationary. Moisture recovery devices consume significantly less energy for
frost protection and are a recommended choice for any device.
• ON / On – the use of pre-heating is allowed - the use is based on demand.
• OFF / Off – the use of pre-heating is prohibited (not recommended). The device ventilates for 10 minutes and stops
the fans if the air drawn from the outside is lower than 0 °C. After 3 hours, it recovers and the device repeats the
same cycle. To turn it off, hold the OK button for less than 3 seconds. In the off state, the heat exchanger may
freeze, which may damage the device. In the summer period, it is not necessary to turn off pre-heating, since
automation uses it only based on the outside air temperature (at minus degrees).
Filter settings and reminder setting
The need to change the filter works with a time-based reminder. The corresponding message is displayed on the control unit or
in the mobile application. It is important to check the filters and clean them regularly from larger dirt, at least six times – the
device does not signal the need for this.

Moisture recovery
Ventilation units are available with two different types of heat exchanger HRV (heat recovery) and ERV (heat and humidity
recovery). In the case of an ERV heat exchanger, in addition to heat, pull-out air humidity is returned. Moisture recovery occurs
only from the air extracted from the rooms, i.e. the special cover of the plate heat exchanger partially captures the moisture of
the extracted air and directs back to the supply air. The amount of moisture to be returned ultimately depends on how much
moisture is generated in the premises during vital activity. A heat exchanger with moisture recovery does not produce additional
moisture itself and its productivity cannot be regulated. Moisture recovery does not threaten the ventilation ducts in any way,
since at supply the humidity never rises very much higher than the humidity of the exhaust (rooms).
If your current device is only a heat recovery (HRV) model, then the heat exchanger can be replaced with a moisture-returning
model. Contact your dealer for this.
Balancing air volumes
In the factory setting, the air volumes (supply and exhaust air) of the device are balanced. When connecting the device to the
ventilation system, the pressure difference in the ducts may drive the air volumes out of balance, and the system may require
balancing. For the best heat recovery efficiency, air volumes should always be in balance.
Changing the speed ratio of fans:
● By increasing the value (+%), the exhaust fan speed is reduced
● By reducing the value (-%) the supply fan speed is reduced
Automatic balancing - during the winter period, the device constantly monitors air humidity, air temperatures and heat recovery
efficiency, and according to the information received, the operating ratio of the engines can be corrected, as well as increase
exhaust and reduce supply. In the event that the operating ratio of the engines is changed, this function is automatically turned
off for 30 minutes.
Air balancing should only be carried out by ventilation specialists! Balancing of air volumes must be carried out with clean filters
and preferably during the off-heating period (outside temperature above 10 degrees), if no condensate water has formed in the
heat exchanger and appliance.
Control of central humidifier
When connecting the central humidifier according to the ventilation unit, the device automatically detects it, and the
corresponding humidifier section is displayed in the mobile application, where it can be controlled.
Control of geothermal preheating and cooling calorifer
If the Airobot device has an optional calorifer control capability, then in the mobile application you will be shown 2 functions in
the "Settings – External heating and cooling" section:
• Ext. Heating / Heating inside – During the winter period, it acts as pre-heating, which allows to preheat the air coming
from the outside to some extent. Electric pre-heating is still used if the calorifer is not enough. The circulation pump is
switched on when the outside air temperature drops below 1 degree. Otherwise, the circulation pump is turned off.
• Ext. Cooling / Cooling inside – During the summer period, a calorifer can be used to cool the supply air. When the
function is activated, the function "Automatic bypass valve (summer cooling)" is turned off, since then the cooling
function begins to control the bypass valve.
o By activating the function, after 5 minutes the bypass valve is opened and the circulation pump is turned
on, and the supply air temperature should decrease.
o The device takes into account the "desired temperature" chosen by the user, and when this is reached
(exhaust temperature), the pump is turned off until the indoor temperature rises again above the desired
temperature.
o The device automatically monitors the minimum allowable supply air temperature, which the device
automatically calculates taking into account the air temperature and humidity in the rooms (calculating the
dew point). If the supply temperature drops too low, the circulation pump shall be stopped until the supply
temperature rises again and then reactivated. If the supply temperature is too low, condensate water may
form on the surface of the non-insulated pipeline, which can damage the structures of the house.

Ext. Heating and Ext. Cooling cannot be turned on at the same time. Seasonally, these features must be switched manually.
The heating function is automatically turned off in the setting when the ambient temperature rises above 13°C, Ext. Cooling
case when the ambient temperature drops below 6°C.
Building automation protocol Modbus
Airobot devices can be controlled using ModBus RTU or ModBus TCP/IP protocol.
Modbus RTU – enabled by default. Connect the A and B wires according to the installation instructions to the LCD contact. In
the case of an RTU connection, it is not possible to use the control unit of the ventilation unit (VE1 or VB2) at the same time.
To establish a Modbus TCP/IP connection, the ventilation unit must be connected to the Internet network. Modbus TCP is
turned off by default. To activate the control unit required or contact the helpdesk, who can remotely activate it.
ON – ModBus is turned on. OFF – ModBus is turned off.
To get the table you need to set up the ModBus parameters (registers), write [email protected]. The setting of control
with house automation should be carried out only by qualified specialists. Incorrect setup can damage the device or the
surrounding environment.
Mobile app
It is possible to control the Airobot ventilation unit through a mobile
application, provided that the device is connected to the Internet network. In
the event that the network connection problem icon is displayed on the
control unit, the connection is missing, and you can try restarting the device
and the network device.
Each Airobot device is assigned an identification number (SN/ID). Your
device ID and password can be found on the device's product sticker or on
the front panel of the device. You can use your device ID and password to
link your device in the Airobot mobile app. A mobile application called
"Airobot 2" can be downloaded from the Google Play Store or App Store
environment. When you first open the application, you must create a user
account and follow the further instructions on the screen.
Security and privacy
The movement of information between the device – the server – mobile application takes place in an encrypted manner. When
connecting the device to the Internet network, every 30 seconds indicators (for example, air temperature, humidity, etc.) are
stored on the server, on the basis of which statistics are displayed to the user in the mobile application. The data may be used
for impersonal analysis and to improve the product.
If possible, connect the device to the Internet network. Airobot equipment software is constantly being developed and it is
possible to enjoy improvements and new functionalities. If you do not want to keep the device constantly in the Internet
network, it is recommended to connect the device to the Internet network for a minimum of one hour every few months – during
this period, the device will automatically pull down the latest software. If it is not possible to connect a device with an Internet
cord to the network, ask the reseller for more information about the wireless Internet receiver.
Airobot devices can be managed remotely, and by contacting the helpdesk (saying your device ID), the Airobot helpdesk may
have access to the data of your devices. This allows us to provide the user with the best experience and faster assistance. In
order to ensure privacy, the Airobot remote management system does not establish links between the user and the device - the
helpdesk can only identify the devices by the device ID in case the user says this when contacting the helpdesk. By saying the
device ID, the user gives permission to view their device data.

The ATS system input gave the device an
alarm or triggered a fire alarm inside the
device (if the air temperature in the duct >
50 degrees)
Make it clear whether the alarm was caused by the ATS system (if
connected) or by an internal fire alarm of the device. If there is no
danger, reset the alarm either by pressing the marked button on
the control unit, RESTART in the mobile application, or unplug for
30 seconds.

PROBLEM
POSSIBLE CAUSE
SOLUTION
The device
works, but the
speed is 0
(fans are
stationary)
Anti-freezing protection is applied to
the device, because the pre-heating is
turned off.
Turn on the frost protection again. In the mobile application From
Settings -> Expert Settings -> Frost Protection ON. Restart the
device by unplugging it.
The device has anti-freezing protection
in place, because the pre-heating has a
physical failure
If PREHEATER or FROST PROTECTION is enabled in the settings
and the device still stops, contact your dealer

Supply and exhaust air volumes may
be unbalanced.
The working relationship of the fans of the ventilation unit must be
balanced by a professional, including the ventilation system
plaphons.

The exhaust pipe is not properly
insulated and the air cools down in the
pipeline
If the exhaust temperature of the device (look at the exhaust
temperature of the device from the control unit) is several degrees
lower than the air temperature in your rooms, then this indicates a
poorly insulated plumbing, and in the pipeline the air will be able to
cool off before reaching the unit. Stop the operation of the device
until the piping is insulated (condensate water may form inside the
piping)
Blockage of plumbing or filters, exhaust
does not work properly.
Check if the exhaust filter is not clogged. Check plumbing blockages.
If necessary, install a new filter or remove the blockage that has
arisen.
The heat exchanger is frozen
Remove the heat exchanger and defrost and contact your dealer –
your device may need a more precise setup to prevent future
freezing.
The bypass valve is open (malfunction)
and cold air escapes into the supply air
AIrobot S - remove the filter on the right side and visually check
whether the valve is properly closed. In the event of a breakdown,
contact the dealer.
The outdoor air grate is not protected
from direct weather conditions and
snow or rain has fallen into the device
Make sure that the device cannot absorb snow or rain through an
outdoor air grate. Remove the heat exchanger and dry.
