Components description

The individual components included in the RCC unit are described in this section. Please use
the figure on page 19 for reference.
Cabinet The outer cabinet parts are made of galvanised steel. The inner part is a closed polystyrene
block. Only the front cover and drip tray need to be removed to insert accessories or replace
components.
The inside of the cabinet is sound- and heat-insulated with polystyrene foam. The cabinet of
the unit is designed to be installed in ambient temperatures of 12 °C to 45 °C.
Heat exchanger The counterflow heat exchanger absorbs the thermal energy from the extract air and
transfers thermal energy to the supply air.
Fans The supply air fan provides fresh outdoor 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 extract 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
bypass damper is used in warm summer conditions, when colder outdoor air can be used to
reduce the indoor temperature if the indoor temperature exceeds a preset upper
temperature limit.
Control The main control of the unit is located at the main PCB.
Air humidity sensor The air humidity sensor in the extract air duct continuously monitors the quality of the
extract air and adjust the airflow accordingly. This operating mode is called "demand
mode". If the unit is connected to an HRC remote control, the level will be indicated on the
display with three level symbols. The demand mode is used to ensure the correct ventilation
rate with the lowest possible power consumption.
The unit is equipped with two ISO Coarse cassette filters. These filters protect the heat
Filter
exchanger and improve the indoor climate by removing dust and particles from both
airflows.
An ePM1 class filter can be obtained as alternative/accessory. If an ePM1 filter is used, it
always is to be installed in the supply airflow where it also removes very small particles from
the air.
The unit is equipped with 2 water drainage spigots for draining condensate. It is compulsory
Water drain
to mount a water hose to the spigots next to T4 to drain off the condensate water to a drain.
Please refer to the connection label on the unit for the correct drainage. The remaining
unused drain must be closed with the supplied cap.
