1. INTRODUCTION
The air handling unit is designed to ensure good ventilation of premises. Air handling unit removes indoor air containing
carbon dioxide, various allergens or dust, while replacing it with filtered fresh air from outside. As the outside air is usually
colder or warmer than the air within the premises, an integrated recuperator collects thermal energy from the indoor air and
transfers the majority of it to the supply air.
When a recuperator is not capable of reaching a desired temperature, heaters or coolers may be additionally activated.

Heat exchangers and heaters (or coolers) are designed to compensate for heat/cool losses during
ventilation, therefore, we do not recommend using the unit as the main heating/cooling source. The
unit may not reach a user-defined supply air temperature when the actual room temperature dif-
fers significantly from the desired room temperature. This will lead to inefficient operation of a heat
exchanger.
Make sure that the unit is installed in a designated location, all ducts and wires are connected before
turning it on. Check for foreign objects, debris or tools inside the unit. Make sure that air filters are
installed and condensate drainage is connected (if necessary). If in doubt, contact your installer or
“Komfovent” representative to make sure that the unit is operational.
We recommend that you always keep your device turned on; when no ventilation is required, you
shall operate the unit in a minimum mode (20%). This will ensure good indoor climatic conditions
and will reduce humidity condensation inside the unit, that may damage electronic components.
This symbol indicates that this product is not to be disposed of with your household waste, according to the WEEE
Directive (2002/96/EC) and your national law. This product should be handed over to a designated collection point, or to
an authorised collection site for recycling waste electrical and electronic equipment (EEE). Improper handling of this type
of waste could have a possible negative impact on the environment and human health due to potentially hazardous sub-
stances that are generally associated with EEE. At the same time, your cooperation in the correct disposal of this product
will contribute to the effective usage of natural resources. For more information about where you can drop off your waste
equipment for recycling, please contact your local city office, waste authority, approved WEEE scheme or your household
waste disposal service.
2. AIR HANDLING UNIT FUNCTIONS
To create a comfortable home environment, you can adjust ventilation intensity and air temperature as well as to create a
weekly ventilation schedule. Various additional functions facilitate control of all ventilation processes and reduce electricity
consumption.
2.1. Temperature control
Temperature in the air handling unit is maintained by measuring the actual temperature and comparing it to the user-
defined temperature. Then, depending on whether the supply air requires heating or cooling, heat exchanger or additional
heaters/coolers are activated. Available temperature control methods:
• Supply air temperature control – the unit supplies air of user-defined temperature.
• Extract air temperature control – the unit automatically selects the supply air temperature to ensure that the extract
air temperature is reached and maintained as quickly as possible. Room air temperature is measured by an integrated
extract air temperature sensor.
• Room temperature control – the unit automatically selects the temperature of supply air to ensure that the room tem-
perature is reached and maintained as measured by the sensor integrated in a remote controller. Control panel must be
installed in a room where temperature maintenance is required.
• Balance – Supplied air temperature will be maintained to be the same as extracted air temperature, therefore, selecting a
desired temperature is not possible. Extract air temperature is measured by an integrated extract air temperature sensor.
To maximize heating/cooling energy savings, priority is always given to the heat exchanger, so due
to its high efficiency, there may be cases where slightly warmer (heating mode) or colder (cooling
mode) than user set temperature air will be supplied.
Selection of temperature control is described in chapter “Control and Settings”.
