HEAT PUMPS RATINGS
* Weights referred to version including pump and buffer tank
- Cooling capacity:
outdoor air temperature 35°C, water temperature 12°C / 7°C
- Heating capacity:
outdoor air temperature 7°C dry bulb and 6.2°C wet bulb, water temperature 40°C/45°C
- Sound power level
measured according to standards EN 23741 and EN 29614-1
- Sound pressure level
measured at a distance of 10 m and a height of 1.5 m above the ground in a free field (fan side).
- The maximum electrical input is the mains electricity that must be available in order for the unit to work.
- The maximum current absorption refers to the current that will trigger the internal safety devices of the unit. It is the maximum current allowed in the unit.
This value may never be exceeded; it must be used as a reference for determining the size of the power supply line and the related safety devices (refer
to the wiring diagram supplied with the units).
