1) These data characterise the size and performance of the system according to EN 14511 with clean heat exchangers. Abbreviations have the
following meaning, e.g. A2 / W35: outside temperature 2°C and heating water supply temperature 35°C. A2 / W35 test, takes into account
defrosting as per EN 14511.
2) According to EN 12102, EN ISO 3744.
3) Power input to pump relates to factory setting, speed 2. Fan is variable speed, rated input relates to maximum input power.
