Notes
(1) Heatloss according to EN12897
(2) DB/WB 7ºC/6ºC - LWC 35ºC (DT=5ºC)
(3) The sound pressure level is measured via a microphone at a 1m distance from the unit. It is a relative value, depending on the distance and acoustic environment.
(4) The sound pressure level mentioned is valid for pump medium speed - 0 ESP / medium speed - nominal flow / high speed - nominal flow
(5) 15ºC-25ºC: BUH only, no heat pump operation = during commisioning
(6) Including piping + PHE + back-up heater; excluding expansion vessel
(7) Value mentioned is connection after ball valves, Connection at unit is G1-1/4 FEMALE
(8) See separate drawing for operation range
(9) For *RLQ* outdoor units \>55ºC BUH only, no heatpump operation
(10) For *RHQ* outdoor units \>50ºC BUH only, no heatpump operation
