Component descriptions
This section describes the individual components of the HCV units included in the standard
delivery.
The external parts of the cabinet are made of powder-coated, AZ-coated iron sheet. The
internal parts of the cabinet are made of polystyrene (EPS). Accessories are installed after the
steel front and EPS doors have been removed. The cabinet is sound and heat insulated with
fire retardant polystyrene foam. The unit is designed for installation in locations with ambient
temperatures ranging from 12 °C to 50 °C.
The unit is equipped with a class G4 cassette filter as standard. These filters protect the heat
exchanger and improve the indoor climate by filtering dust and other particles from the air.
An F7 filter (pollen filter) is available as an accessory. The F7 filter is always located on the
supply side - as shown at the top of the unit.
In the counter flow heat exchanger, heat energy is transferred from the extract air to the sup-
ply air, thus saving energy for heating
The supply fan passes fresh air from outside through the heat exchanger to the ventilated
rooms inside.
The extract air fan extracts vitiated humid air from the wet rooms in the home.
The motorised bypass damper overrides the heat exchanger functionality. It is used in
summer in warm conditions where the cooler outdoor air can be used to reduce the indoor
temperature when the indoor temperature exceeds an upper temperature limit.
The unit is equipped with two outlets for condensate.
One of these must be connected to the drain hose (1 m drain hose is included in the delivery)
so that condensate can be led to a drain.
The correct connection to the condensate outlet is shown at the top of the unit and on page
33 of this service manual.
The unit is equipped with a wall bracket, for use when the unit is to be mounted on the wall.
The humidity sensor will continuously monitor the quality of the extract air and adjust the
airflow accordingly. This mode of operation is called demand-controlled mode. If an HRC
Remote Control is connected, the level will be shown in the display using the Level 3 icon.
Demand-controlled operation will result in the correct ventilation level with the lowest possi-
ble electricity consumption.
The desired operating mode can be selected and changed via the membrane panel located
on the front of the unit.
