2. This data indicates the size and capacity of the system according to EN 14511. For an analysis of the economic and energy efficiency of the system, other parameters, in

particular the defrosting capacity, the bivalence point and regulation, should also be taken into consideration. These figures are only achieved with clean heat exchangers.

Information on maintenance, commissioning and operation can be found in the respective sections of the installation and operating instructions.

Notation such as A2 / W35 should be read as follows: Outside temperature 2 °C and heating water flow temperature 35 °C

3. Sound power level in accordance with EN 12102, measurement uncertainty ±1.5 dB

4. Audibility of tonal components in accordance with DIS47315 / 150257, April 2004: "inaudible"

5. The heat output and COP is reduced by approx. 5% in lower operation

6. The specified sound pressure level represents the free sound area level. The measured value can deviate by up to 16 dB(A) depending on the installation location

7. Operating point according to EN 14825: Low-temperature application with average climate, partial-load ratio B; heat output: 14.3

8. Maximum heat output at the operating point A-7 / W55; Full-load operation: 21.9 kW; Lower operation: 21.5 kW; Silent Mode: 11.5 kW.

9. Note that additional space is required for pipe connections, operation and maintenance

10.see CE declaration of conformity

11.The heat circulating pump and the heat pump manager must always be ready for operation
