Important Information about the Genius Combi Unit

Important information about
the Genius combi-unit
Service provided by Systemair:
If the system is installed according to plan, Systemair will
provide a warranty for the function.
For this, the following points are critical:
• The system was planned by Systemair.
• The system was installed and commissioned as
planned.
• Only Systemair products were installed.
Application limits
The combi-unit is designed for use in passive houses,
lowest-/low-energy houses, and, in some cases, in
standard energy-efcient houses. The maximum heating
load is 6 kW. A heating load of ≤ 5 kW is required.
The air volume for residential ventilation is limited.
From this result the following reference values for the
application limits:
• Passive house: max. 220 m² living area
• Lowest-energy house (Energy Efcient House 40):
max. 200 m² living area
• Low-energy house (Energy Efcient House 55):
max. 180 m² living area
• Standard Energy Efcient House (according to EnEV
2016, formerly Energy Efcient House 70):
max. 140 m² living area
• Furthermore, the building needs to be appropriately
airtight. Recommended value: < 0.6 per hour
As soon as the application limit is approached for the
relevant house standard, detailed consideration is required
and the manufacturer must be consulted. For example,
this could require a heating demand calculation / heating
load calculation, as well as evidence of the airtightness of
the building (blower-door test).
• If a wood-burning stove is planned, this must be
independent of the room air and DIBt-certied. This
means pressure monitoring is generally not necessary
and a shutdown of the system can be excluded.
This is the only way to ensure the unit functions
perfectly. If pressure monitoring is required, this
must be implemented thermally. The "oven function"
enables heat to be transported around the entire
house through the duct network. Parallel operation of
a replace and ventilation system must generally be
agreed with the responsible district chimney sweep.
• As well as the fresh and exhaust air pipes, all the
supply air pipes must be insulated so they are airtight.
This prevents heat losses during heating as well as
condensation during cooling operation.
• It is possible to limit both the heat pump performance
and the secondary air volumetric ow, for example,
for small residential units or passive houses. However,
the manufacturer must be consulted.
• The unit is designed for use in a single-family house
or a residential unit.
• At least one room controller (accessories) is required.
We recommend one controller per supply air room.
• The use of reheating elements (accessories) is
recommended for all house standards (activated for
"defrost" mode-comfort, emergency function).
Heating elements are absolutely necessary for low-
energy houses (for covering peak loads), as well as
standard energy-efcient houses.
• For very cold external temperatures, a preheater for
the heat pump (accessories) is needed to ensure
operational reliability. Systemair offers the heater as
an option and also incorporates it in the plan, so that
it is possible to retrot it if required.
• Do not use the ventilation system while the oor
screed is drying, because damage to the ventilation
unit may occur due to the formation of excessive
condensation. Any operation during the building
phase must be excluded to prevent contamination of
the duct network and the unit.
• If commissioned in winter, the rst heating-through of
the building must be performed by the builder/client
on-site.
