| 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) - Based on a dT of 45 K | |||||
| (3) - Including piping + back-up heater; excluding expansion vessel | |||||
| (4) - Excluding the water in the unit. This minimum water volume is sufficient for most applications. During critical processes extra water may be required. | |||||
| (5) - 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°. | |||||
| (6) - 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 | |||||
