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.
Swegon CASA R3 is designed for detached houses,
multi-dwelling houses and holiday cottages less than
150 m

. The ventilation unit can be used both for new
construction and renovation projects. The R3 ventilation
unit can also be installed together with a cooker hood
instead of a spice rack above the cooker.

1.2 Fans
Swegon CASA R3 is equipped with energy efficient EC
fans.
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.)
The unit’s weekly timer can change operation modes
and temperature setpoint at the preset times. It is always
possible to override the weekly timer and change the
operation mode from a control panel or a Smart cooker
hood.
