Product information
MIKrovent® is a local ventilation device that allows ventilation of the room with minimal heat
losses, due to efficient recovery (heat recovery). MIKrovent® consists of two fans, a heat exchanger
(recuperator) and two filters. The first fan is intended for the supply of external air into the room,
and the other for the exhaust of air from the room. The internal air and the external air flow
circulate through the heat exchanger, where the internal air sends heat to the outside air on the
way to the room without mixing. By doing this we ensure that the outside air preheats before
entering the room, and the air filter ensures that there is no dust entry into the device and into the
room.
Package includes:
• 1x MIKrovent device with installation material,
• 1x remote control with 2x AAA batteries, and
• 1x user instructions.
The device is not meant for outdoor use.
Power supply: the device must be connected to a 230 V / 50 Hz
grounded electrical socket. The installation must be done in
accordance with the regulations of the country where the device will
be used.

Usage of MIKrovent® Office60 / Professional
120
MIKrovent® Office 60/ Professional
120
is intended for use from -25° to 50°C outdoor
temperature. If the outdoor temperature is around 5°C, MIKrovent will work with interruptions
to prevent the condensation from freezing, resulting from its operation in the heat exchanger.
OUTDOOR AIR INLET
MIKrovent® Office60/ Professional
120
has special air nozzles on each side, allowing you to adjust
the air flow direction. The air flow is routed by rotating the nozzle for 180°. The longest range the breakthrough of fresh air into the room - is achieved if you turn the two nozzles
to one another (as in the figure on the right).
Modes of operation
The device has 4 modes of operation:
MANUAL M is a way to adjust the device to your own needs. The user himself adjusts the
amount of air through the device between 20 and 60 m3/h for MIKrovent Office60, and between
60 to 120 m3/h for MIKrovent Professional
120
. The user can choose between 5 levels of
operation, with 1 being the less, and 5 being the most intensive level of operation of the device.
AUTO A is a way to use MIKrovent when we want the device to operate automatically, or
when we do not use ventilated place for a longer time. The device regulates the amount of
incoming and outgoing air according to the relative humidity and temperature in the room (if
the device has a built-in CO2, VOC or radon sensor, it is also regulated according to these
sensors). By increasing the amount of moisture and CO2 concentration, the operating power of
the device increases. Thanks to its own electronics protocol, the device will automatically adjust
its optimum performance according to the detected amount of temperature, humidity and CO2,
and ppm particles.
OUT The device only pumps the air from the room. This method is used when we want to get
rid of bad air in the room quickly. In this mode, 5 levels of device operation are available. This
method is not recommended when using an open fire such as, for example, fireplace. Due to
vacuum in the room, harmful gases (CO2 etc…) can escape from the fireplace. When air is
discharged, incomplete combustion and formation of carbon monoxide, which is fatal, may
occur.
IN The device only supplies outside air to the room. Usually it is used for the natural cooling of
the rooms in the summer time, because with this way at night we bring a lot of fresh and cold
air. In the case when used in the room of a furnace or a fireplace, due to overpressure the
combustion air intake increases and thus improves the combustion in these devices. In this
mode, we have 5 levels of operation of the device, where the level 1 is also at least, and the 5th
degree is the most intensive level of operation of the device.

Setting a weekly programmer
1. For proper operation of the device, the remote control must always be directed
to the device - it must be in the field of view of the device.
2. When we want to use the weekly programmer, we switch it on on by holding
the MODE key for 3 seconds and with the same in the same way we stop its
operation.
With the programmer we have the possibility of setting 5 time sections for each
day of the week. In each time section, MIKrovent can operate with a different
mode of operation: with manual settings (MANUAL), automatic (AUTO), outside
air inlet (In) and inside air outlet (Out).
The device automatically turns off automatically between time sections. To
avoid this, it is necessary to create a minute break between the time sections,
such as:
• Time section 1: between 22:00 and 22:50
• Time section 2: between 22:51 and 23:59, and so on.
3. To adjust the sections, first press the PROG button for about three seconds until
it starts blinking.
4. Use the keys to scroll through the days of the week. When we get to the
right, we confirm this with the OK key.
5. With the key we can move between 5 time sections among which we can
choose.
6. To set the hours of the first day section, use the keys to select the desired hour
and confirm with the OK button. Repeat this process for setting the time for
turning the device on and off.
7. To set the operating mode, press the MODE button and select the desired
program with the keys .
8. Press the SPEED key to set the operating strength and use the keys.
9. To select time sections for a new day, we scroll back with the key until the
week-sign starts flashing/blinking again. Press key to move one step back, or
one step further.
10. When finished, press the OK button and hold it for 3 seconds so there are no
more flashes on the screen.
