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. These tariffs are linked to the right for the energy supply
companies to separate the heat pump daily up to three times for one or two hours from the power network. The energy supply compa-
nies usually lay down mandatory interruption times. A sufficient hot water buffer is recommended to ensure constant comfort.
The combi unit Genius can not be operated with a buffer based on the pure air heating principle. However, a house with low energy or
passive house standard acts as a buffer. An appropriate insulation of the house saves enough energy to bridge interruption times.
13.1.2 Heat Pump Special Rate without Forced Interruption
The power input of the combi unit Genius is lower than 3 kW. Many energy supply companies offer a heat pump special rate without
forced interruption for this performance class.
13.1.3 Heating current/Night current
To avoid interruption times, the so called heat current or night current an is an alternative. The tariff is often split in high tariff periods
(HT) and low-tariff period (LT).
"
Select this tariff if the unit approaches the operating limits in the low energy rate and no heat pump tariff is available without forced
interruption.
13.2 Setpoint Temperatures/Settings
13.2.1 Winter Operation
If the operating limits and the requirements meet planning and installation, the system will ensure the comfort even at low outdoor tem-
peratures without additional heating. To optimize the efficiency of the system, a very low supply air temperature is necessary. However, it
must be sufficiently high that it can cover the heat demand.
Changing the max. supply air temperature
NOTE
The default settings ensure usually a comfortable operation with high energy efficiency. The temperature can be
adjusted individually.
A curve is stored and described on the Settings page which changes the maximum supply air temperature depending on the outdoor
temperature. It can be shifted parallel for fine adjustment. The temperature can also be set manually. Due to the modulating operation
of the combi unit, the supply air temperature decreases when approaching the room temperature setpoint. In addition, the heat pump
decreases its performance automatically after reaching the max. supply air temperature.
RECOMMENDATION
Modifying the curve or the use of manual settings requires a corresponding user behaviour. It should only be performed
by technically skilled persons.
At lower insulation standard, large living area or longer cold periods, it may be necessary to shift the curve upwards. The default curve of
the maximum supply air temperature is a good method to control the temperature of the heat generator only as high as necessary. Due
to different conditions, a readjustment can be necessary.
