1. General Description

The most important function of the ventilation system
is to ensure clean and fresh indoor air and to remove
moisture. The air in the home should be changed at
a continuous and sufficient rate to ensure a pleasant
indoor climate and avoid damage to building elements
caused by dampness.
The Swegon CASA R2 is designed for detached houses,
apartment blocks and holiday cottages up to 140 m
Suitable for both new builds and renovation where the
unit's unique duct placement is suitable for the replace-
ment of older units. Installation behind a kitchen cabinet
door is possible thanks to the unit's flat front.
• Air flow range: 18 - 60 l/s
• Heat exchanger temperature efficiency: up to 83%
• Built-in humidity sensor as standard.
• Constant supply air temperature control
• Energy efficient EC fans with a low noise level
• Available in right or left handed version (supply)
• Can be installed above a stove with the cooker hood
installed directly under the unit.
• The unit is built to standard dimensions and can be in-
stalled in line with existing cabinet frames and hatches.
• Built-in electric heater for reheating as standard.

1.1 Enclosure

The ventilation unit conforms to enclosure class IP21
when the cover is closed.

1.2 Fans

The Swegon CASA R2 is equipped with energy-efficient
fans with speed controlled EC motors. The fans have
quick-fit connectors making the fans easily removable
from the unit, if required.
The fans can be controlled in four operating modes and
steplessly with Smart functions:
• Boost = maximum commissioned air flow is used
when the ventilation requirement increases, e.g. for
cooking, showering or drying laundry.
• Home = normal air flow. In normal cases guarantees
healthy indoor air quality.
• Away = low air flow. Reduces power consumption
when no one is in the house.
• Travelling = very low air flow and lower supply air tem-
perature. Used when house is empty long period. (Can
only be selected from a Smart control panel.)
