| Notes | (1) - Operation area is extended to lower flow rates only in case the unit operates with heat pump only. (Not in startup, no BUH operation, no defrost operation). | ||||
| (2) - Including piping + back-up heater; excluding expansion vessel | |||||
| (3) - Excluding the water in the unit. This minimum water volume is sufficient for most applications. During critical processes extra water may be required. | |||||
| (4) - Measured with a pressure drop of 10 kPa in the heating system at an operating condition of leaving water 47-55°C in a room with an ambient of 20°C. DB/WB 7°C/6°. | |||||
| (5) - Value measured in an anechoic room at 1m distance from the unit. It is a relative value, depending on the distance and acoustic environment. The sound pressure level mentioned is measured with a pressure drop of 10 kPa in the heating system at an operatin | |||||
| (6) - Refer to operation range of the unit. | |||||
| (7) - Depends on operation mode, refer to installation manual. | |||||
| (8) - Above mentioned power supply of the hydrobox is for the backup heater only. The switch box and the pump of the hydrobox are supplied via the outdoor unit. The optional domestic hot water tank has a separate power supply. | |||||
