The individual components of the units included in the standard scope of delivery are
described in this section.
The outer parts of the cabinet are made of aluzinc sheet metal. To add accessories or replace
components, the front cover must be removed. The inside of the cabinet is sound- and heat
insulated with a fire-resistant polystyrene foam block.
The unit is designed for installation in locations with ambient temperatures of -12 °C to 45 °C.
The counterflow heat exchanger absorbs the thermal energy from the extract air and transfers
thermal energy to the supply air.
The supply air fan provides fresh outside air via the heat exchanger to the distribution ducts
through which the air is distributed to bedrooms, living rooms, children's rooms, study spaces,
etc. The supply air fan is also used to distribute the air. The exhaust air fan extracts stale,
humid indoor air from kitchens, bathrooms, toilets, utility rooms and other wet rooms in the
dwelling.
The operation of the heat exchanger is deactivated by the motorised bypass damper. The
bypass damper is used in warm summer conditions, when colder outside air can be used to
reduce the indoor temperature if the indoor temperature exceeds a preset upper temperature
limit.
The control unit of the appliance is named PCB. The main PCB electrically connects all
electrical and electronic parts and various accessory components.
The control unit on the front of the unit indicates the operating mode and the fan level in
which the unit is operating. Both can be selected and changed via the control unit. The
control unit also provides other functions such as resetting the filter alarm.
The unit is equipped with 4 temperature sensors that continuously monitor the temperature
changes on 4 sides of the heat exchanger, i.e. in outside air, supply air, extract air and exhaust
air.
The humidity sensor continuously monitors the quality of the extract air and adjusts the
airflow accordingly.
This operating mode is called demand-controlled mode. If an HRC remote control is
connected, the level is indicated on the display with the level 3 symbol. A demand-controlled
operation ensures that the correct ventilation level is achieved with the lowest possible power
consumption.
The unit is equipped with two ISO Coarse cassette filters. These filters protect the heat
exchanger and improve the indoor climate by removing dust and particles from both airflows.
A filter of class ePM1>50 % (pollen filter) is available as an alternative/accessory. When using
an ePM1 filter, always install it between the outside air inlet and the heat exchanger.
The unit is equipped with two drains for the condensate. One of the drains must be
connected to the drain hose (1 m drain hose is included) so that the condensate can be
directed to a drain. The correct connection to the condensate drain is indicated in the chapter
"Installation".
A wall bracket is included for mounting the unit on a wall.
