Notes
Nominal water flow rate for Dt = 10°C
Maximum water flow rate for Dt = 5°C
(1) Sound levels are measured at condition 1: EW: 55°C; LW: 65°C
(2) Sound levels are measured at condition 3: EW: 70°C; LW: 80°C
Sound level in night quiet mode is measured at condition 1: EW: 55°C; LW: 65°C
Sound level is valid in free field condition because it is measured in a semi-anechoic room. Measured
value under actual installation conditions will be higher due to environmental noise and sound
reflections. Values are sound pressure values measured at all sides (front, back, left, right, top) at 1m
distance. The values do not occur simultaneously on all mentioned sides.

Note:
ERRQ units include special equipment (insulation, heater sheet, ...) to ensure good operation in areas where low ambient temperature can occur together with high humidity conditions. In such conditions the ERSQ models may experience
problems with severe ice build up on the aircooled coil. In case such conditions are expected, the ERRQ must be installed instead. These models contain countermeasures (insulation, heater sheet, ...) to prevent freeze up.

Remarks: Other combinations are not guaranteed
(1) If bottom plate heater tape is installed (EKBPHTH16A), it is not allowed to install a drain kit
(2) requires Demand PCB EKRP1AHTA.
(3) Required to install to be able to connect Roomthermostat or BUH kit.
(4) Same controller as supplied with Cascade unit can be mounted parallel or on other location. If 2 controllers are installed, the installer needs to select 1 master and 1 slave.
(5) Only required if tank is NOT mounted on top of cascade indoor unit.

- The above data is valid in free field condition, because it is measured in a semi-anechoic
room. If sound is measured under actual installation conditions, the measured value will be
higher due to environmental noise and sound reflections. Choose the installation location
carefully and do not install in a sound sensitive environment (e.g. living room, bedroom, . . .)
- dB(A) = A-weighted sound power level (A-scale according to IEC)
- EW = Entering water temperature
- LW = Leaving water temperature
- Reference acoustic pressure 0dB = 20µPa
- Sound pressure level of low sound mode n°2 and n°3 is lower than n°1
- (*) Does not occur simultanuously on all sides.

Notes
- Measured according to ISO3744
- Reference acoustic intensity 0dB = 10E-6µW/m_
- dBA=A-weighted sound power level
- Unit condition: Ta=7/6°C - Heating setpoint70/80°C - Maximum compressor frequency
- If sound is measured under actual installation conditions, the measured value will be higher due to environmental noise and sound
reflections. Choose the installation location carefully and do not install in a sound sensitive environment (e.g. living room, bedroom, . . .)

In such conditions ERQS*5V1/Y1) models may experience problems with severe ice build up on the aircooled coil.
In case such conditions are expected the ERRQ*(V1/Y1) must be installed instead.
These models contain countermeasures to prevent freeze up.

1. The ESP curves are the maximum ESP curves (pump rpm: 4000).
The pump of the indoor module is inverter controlled and controls to
have a fixed _T between return and leaving water temperature.
2. In case of installing a domestic hot water tank there is an additional
pressure drop over the three way valve (delivered as accessory with the
tank)
Flow [l/min]
ESP: External static pressure
Flow: waterflow through the unit
Warning
1. Selecting a flow outside the curves can cause damage to or malfunction
of the unit. See also minimum and maximum allowed water flowrange
in the technical specifications.
2. Water quality must be according to EN directive EC 98/83 EC.
