General Information

1.3 Using the Systemair-Cloud
Conrming the Systemair-Cloud enables Systemair having access to your controller and its settings. It goes without saying that we do this
only after request/permission of the unit user.
Systemair-Cloud provides qualied support (malfunctions, incorrect settings, software errors etc.) in an easy and quick way which also
saves costs and waiting time.
NOTE
Modications of the software settings can inuence the energy consumption and effectivity of the unit.
1.4 Heat Pump Special Rate/Utility Lock
Before unit installation, consult the utility company for your suitable rate.
1.5 Notes on Planning and Installation
Systemair is happy to do all the planning and project engineering for you, e.g.
• Determination of the air quantities using the building plans
• Conguration of the system using modern CAD software
• Quote generation with a list of specications and the associated prices
• Creation of assembly plans
• Delivery of the system components to the building site
• Support during assembly, commissioning and maintenance
1.5.1 Professional Planning
Observe the following during planning and electrical installation:
• Increased air volume ow during heating or cooling operation. This results in a larger supply air duct system. High air velocities and
noise development can be avoided.
• Air tightness and insulation of the supply air ducts require increased specications.
• PTC elements are required in most cases.
• Room controllers are obligatory.
• An additional duct system for secondary air is necessary.
1.5.2 Professional installation
"Choose the insulation of the supply air ducts within the shell (warm area) so that the air volume provides the heating performance in
each supply air room.
"Isolate supply air ducts in cold areas with an insulation of min. 50 mm.
"Ensure air tightness of the system to minimize heat loss.
"Use silencers for all unit connections.
"Make sure the installation is diffusion resistant, to prevent condensation forming during cooling.
NOTE
To ensure a proper system operation, the installation must be carried out according to the state of the art.
1.5.3 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.

2 Important Safety Information
2.1 Safety Notes
Observe the following safety instructions:
• Any work on the unit and rst commissioning must be carried out by an expert technician.
• The expert technician is responsible for installation and rst commissioning according to the applicable rules and regulations.
• Operate the unit only completely installed and with all safety devices.
• Check the lter regularly for contaminations.
• Never readjust the room supply and extract air valves. They will be adjusted during commissioning.
• Never modify the internal electrics and control.
• Operate the combi unit permanently with frost protection.
• 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.
• 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.
• Reheating elements are absolutely necessary for low-energy houses (for covering peak loads), as well as standard energy-efcient
houses. The use of reheating elements (accessories) is recommended for all house standards (activated for "defrost" mode-comfort,
emergency function).
WARNING
Electric shock
Electrics and electronics can become a lethal danger through ingress of liquids.
» The device shall not be exposed to dripping or splashing!
WARNING
Burning hazard
Risk of scalds with water temperatures higher than 43 °C.
» Do not open the hot water storage tank!
WARNING
Impacts and crushing
The ventilation module is not xed to the base module with bolts. At a gradient of more than 30°, the ventilation unit
can tip and fall down.
» Do not tilt the unit more than max. 30° from the vertical position!
» Wear a helmet!

2.2 Personnel
2.2.1 Personnel for Installation, Commissioning, Maintenance, Cleaning and Remedying Faults
This instruction manual contains information about installation, commissioning, maintenance, cleaning and remedying faults.
It is addressed to the expert technician.
In order to ensure a proper function observe the following information:
"Carry out any work only according to the service manual.
"Carry out any work only according to the actual standards and regulations.
"Instruct the operator in function, operation and maintenance of the combi unit.
"Inform the operator of possible hazards during the operation of the unit.
2.2.2 Operation Personnel
The combi unit can be operated by untrained personnel. Information to this can be found in the operation manual.
2.3 Intended Use
The unit is a complete system with heat recovery for central ventilation, hot water supply and heating. The intended use of the unit are
domestic areas and can be safely operated by not trained persons. The unit can also be applied in non domestic areas e.g. small companies
with similarly use.
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:
• 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 1/h
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).
I
f 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.
• 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.
• At least one room controller (accessories) is required. We recommend one controller per supply air room.
If larger houses/residential units (at a correspondingly lower heating load, e.g. for passive houses) are to be equipped with the Genius
combi-unit, there is an option to use stronger fans to ensure the required air exchange. Please get in touch with Systemair early on in the
planning phase).

3.2.2 Optional extra - Accessories
Circulation system
A hot water circulation is not recommended for energetic reasons. If a hot water circulation is necessary due to unfavourable ducting, it
must be carried out according to the standards (see „13.2.3 Hot water generation“ page 102)
Geothermal heat exchanger
The temperature in the earth is almost constant throughout the year. Thus, the heat exchanger is suitable to pre-heat cold outdoor air in
winter. Warm summer air can be cooled down before entering the interior rooms.
- Air-to-air geothermal heat exchanger
The air to air geothermal heat exchanger should be connected to the outdoor air of the heat pump to ensure higher energy efciency.
A combined connection to the ventilation unit is not possible due to a varying supply air intake of the heat pump. This results partially in
high volumetric ows and a proper controlled residential ventilation operation can not be ensured.
- Brine-to-air heat exchanger
A brine to air heat exchanger is an alternative. Both supply air intakes can be connected together due to the separated systems. Ensure
that the specications of the brine to air heat exchanger is adapted to the heat pump (air ow rate).

4 Description of the System
The Combi Unit Genius realizes the complete building services for energy efcient buildings without water-based heating system.
Modern buildings are planned with thicker envelopes. Thus, a mechanical ventilation is more and more necessary. New buildings as well
as renovated buildings have higher insulation standards with less heating loads. Consequently, conventional heating systems are often
over-dimensioned.
Systemair provides with the Combi Unit Genius a new designed heating system based on heating and cooling via ventilation ducts. This
can be achieved by temporarily increasing the volumetric ow in combination with an air-air/air-water-heat pump. This heat pump also
provides warm water.
Furthermore, planning and design of the building equipment can be minimized.
4.1 The Combi Unit Genius in Detail

Figure 1: Genius in detail
4.1.1 Heat Pump/Cooling Circuit
A steplessly controlled air-air heat pump heats in winter and cools in summer. The heat pump adjusts its performance according to the
requirements. This guarantees an energy efcient operation. Additional air is removed from the living area via a separate duct system
and led back after treatment (heating or cooling) to living and sleeping areas. This is a pure air heating/cooling system. The extract
system remains unaffected. An odour or mass transfer from the extract air rooms into the supply air is excluded.
The hot water generation with a 150 litres drinking water tank is ensured by an additional plate heat exchanger. This ensures hot water
comfort because water treatment works during all operating modes. The water will be heated or cooled to the desired temperature on
demand.
12
Description of the System
Genius - V 1.0

4.1.2 Controlled Residential Ventilation
A controlled residential ventilation with heat recovery is integrated in the unit. It provides a balanced, pleasant indoor climate year-round,
ensures constantly fresh air into the living rooms and transfers used air to the outside. At heat recovery, heat is transferred from the
extract air to the supply air, thus remaining in the building.
The rotating heat exchanger is used for heat recovery in the Combi Unit Genius:
Due to the rotation of the heat exchanger, supply and extract air ow through in one revolution alternately by the cells. Thus the heat
storage wheel transfers the heat of the extract air by rotation to the supply air. In summer, the principle works in reverse by the cooler
extract air precools the warmer supply air. A rotating heat exchanger recovers not only heat but also humidity. At low outdoor tempera-
tures, the condensation of the extract air is transferred to the supply air, so that it is humidied. In summer, the room humidity will be
transported from the interior to the exterior.
4.2 Operation in Combination with Room Air Independent Fireplaces (Furnace
Function)
NOTE
This function must be activated and deactivated manually.
The steps correspond to the following powers of the secondary air fan:
• Step 1 60%
• Step 2 80%
• Step 3 100%
The combi unit Genius can be used in combination with room air independent replaces. Since the combi unit ensures the complete
heating function, it must not be switched off. This is only possible with a room air independent version.
In a combined operation of a ventilation system with an air-ventilated replace it must be avoided that exhaust of the re place can get
in the room due to a formation of a negative pressure. This can be realized either through mutual operation (ventilation system switches
off when operating the replace) or by a pressure-controlled mode (ventilation system switches off when a predetermined negative
pressure is exceeded, which is monitored by a differential pressure device).
NOTE
Since the combi unit also ensures the complete heating function any shutdown must be excluded.
A room air independent replace equally distributes the heat of the replace in the house by the secondary air operation of the system.
This represents a classic example for secondary air heating with a tiled stove.
The heat of the replace is distributed through the secondary and the following supply air duct system. Thus, the heat pump runs corre-
spondingly less. In the best of case not at all as long as the replace is in operation. The heat is selectively discharged by the step opera-
tion. An overheating of the living area can be additionally avoided.
If the heat pump receives an additional heating demand, the secondary air fan switches to controlled operation. The fan runs parallel to
the heat pump. After the heat pump is switched off, the fan returns to the set step of the furnace operation.
NOTE
To avoid complications when combining controlled residential ventilation systems and replaces (rewood or pellets), it
is essential to agree with the district master chimney sweep.
For wood stoves, two types must be distinguished: room air dependent and room air independent. An room air inde-
pendent wood stove (declared by the manufacturer) is only accepted when having an approval. If not, the chimney
sweep must consider it as room air dependent. In this case the parameter Add. Frost Protection must be set to Off (see
„Rotor settings“ page 73).
If a safety device is required, the controller is precongured - see “Wiring Diagram”.
