Delivery and Accessories 3 Delivery and Accessories "" Check the delivery for any possible damages. 3.1 Delivery Contents WARNING Danger of impacts and crushing due to falling or tipping ventilation unit! The ventilation module is only resting (not fixed in place) on top of the base and heat pump module. At a gradient of >30° from the vertical position, the ventilation unit can tip, slip and fall down. »» Secure the Genius against tipping! »» Do not tilt the Genius more than max.
Delivery and Accessories 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.
Description of the System 4 Description of the System The Combi Unit Genius realizes the complete building services for energy efficient 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.
Description of the System 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.
Description of the System 4.3 Technical Data NOTE 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). Genius Unit Data max. heating capacity kW 6 max.

Consequence: The setpoint temperatures will change. The room will no longer be controlled individually. Depending on the settings, the temperature follows a different set value.
Comfort and Energy Efficiency 13 Comfort and Energy Efficiency 13.1 Utility Company Rates RECOMMENDATION Before unit installation, consult the utility company and the electrical installation company for your suitable rate. 13.1.1 Heat Pump Special Rate with Forced Interruption Most energy supply companies (utilities) offer special rates for heat pumps.
Comfort and Energy Efficiency Changing the heating curve NOTE The default settings ensure usually a comfortable operation with high energy efficiency. The temperature can be adjusted individually. Any reduction of the setpoint room temperatures by 1 °C leads to an energy saving of about 6%. However, you should never give up comfort. Therefore, a heating curve was stored as a default setting in Settings.
Comfort and Energy Efficiency An increase or decrease of the minimum value is only useful in exceptional cases. It may be necessary e.g. according to an unintended high solar entry, to reduce the supply air temperature over a certain time period to discharge the cooling load. Cooling recovery by the rotating heat exchanger The cooling recovery by the rotary heat exchanger can not to be compared to active cooling. The warm outdoor air is only pre-heated by the cooler extract air.
Comfort and Energy Efficiency NOTE One- and two-family houses are excluded from the applicable requirements to the construction and operation of drinking water installations. Relevant regulations according to the state of the art which describe effective prevention of legionella growth in drinking water installations, have only an advisory purpose for small systems. They are not made mandatory. Therefore, it is in the users discretion whether and how he uses them.
