(1)
Heatloss according to EN12897.
(2)
Ambient temperature 35°C – leaving water evaporator 7°C (DT=5°C).
(3)
DB/WB 7°C/6°C – leaving water condenser 35°C (DT=5°C).
(4)
The sound pressure level is measured via a microphone at 1 m from the unit. It is a relative value, depending on the distance and acoustic
environment. The sound pressure level mentioned is valid for pump medium speed – 0 external static pressure/medium speed – nominal flow/
high speed – nominal flow.
(5)
15°C~25°C: backup heater only, no heat pump operation during commissioning..
(6)
Including piping, plate heat exchanger, and backup heater/excluding expansion vessel.
(7)
Value mentioned is connection after ball valves. It is the same as the connection at the unit (G 1­1/4" female).
(8)
Ambient temperature 35°C – leaving water evaporator 18°C (DT=5°C).
(9)
For details, see operation range drawing.
(10)
For outdoor units: >55°C backup heater only, no heat pump operation.
(11)
Minimum flow is mentioned for heat pump operation. To allow backup heater to operate safely, a higher minimum flow is required: 12 l/min.
(12)
Refer to operation range for details.
(13)
DB/WB 7°C/6°C – leaving water condenser 45°C (DT=5°C).
