This section describes the individual components of the HCH units included in the standard
delivery.
The external parts of the cabinet are made of aluzink sheet metal. The internal parts of the
cabinet are made of polystyrene (EPS). Accessories are installed after the steel front 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 45 °C.The unit is designed for installation in locations with ambient temperatures
ranging from +12 °C to 45 °C.
The unit is equipped with an ISO Coarse 75% filter as standard. These filters protect the heat
exchanger and improve the indoor climate by filtering dust and other particles from the air.
An ePM1>50% filter (pollen filter) is available as an accessory. The pollen filter is always locat-
ed on the outdoor - see also page 16.
In the counterflow heat exchanger, heat energy is transferred from the extract air to the sup-
ply air, thus saving energy for heating.
The supply fan brings fresh air from outside through the heat exchanger to the ventilated
rooms inside.
The extract air fan extracts stale humid air from the wet rooms in the dwelling.
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 an outlet for condensate.
It must be connected to the drain hose, so that condensate can be led to a drain.
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 power consumption.
The control panel located on the front of the unit shows the operating mode and the fan
speed level in which the HCH is running. Both can be selected and changed via the control
panel. The control panel also has other functions as e.g. reset of filter alarm.
