1 Features
IndoorUnit VRVSystems HXHD-AHightemper • Air to water connection to VRV for applications such as bathrooms,
sinks, underfloor heating, radiators and air handling units
• Free heating provided by transferring heat from areas requiring
cooling to areas requiring heating or hot water
• Uses heat pump technology to produce hot water efficiently,
providing up to 17% savings compared to a gas boiler
• Possibility to connect thermal solar collectors to the domestic hot
water tank
• Leaving water temperature range from 25 to 80°C without electric
heater
• Super wide operating range for hot water production from -20 to
+43°C ambient outdoor temperature
• Saves time on system design as all water-side components are fully
integrated with direct control over leaving water temperature
• Various control possibilities with weather dependant set point or
thermostat control
• The indoor unit and domestic hot water tank can be stacked to save
space, or installed next to each other, if only limited height is available
• Requires no gas connection or oil tank
• Connectable to VRV III heat recovery (REYAQ-P)

Notes
(1) EW 40°C; LW 45°C; Dt 5°C; ambient conditions: 7°CDB/6°CWB
(2) For water Dt 5°C
(3) 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.
(4) 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.
(5) Sound levels are measured at: EW 55°C; LW 65°C
(6) Sound levels are measured at: EW 70°C; LW 80°C
(7) In accordance with EN/IEC 61000-3-11, it may be necessary to consult the distribution network operator to ensure that the equipment is connected only to a supply with Zsys
(system impedance) ≤Zmax
(8) EN/IEC 61000-3-11: European/international technical standard setting the limits for voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for
equipment with rated ≤75A
(9) EN/IEC 61000-3-12: European/international technical standard setting the limits for harmonic currents produced by equipment connected to public low-voltage system with input

- Measured according to ISO 3744
- Reference acoustic pressure 0dB = 10e-6 W/m

- dBA = A-weighted sound power level
- Unit condition: Ta = 7/6°C - heating setpoint 55/65°C - maximum compressor frequency
- If sound is measured under actual installation conditions, the measured value will be higher due to environmental noise and sound reections.
Choos the installation location carefully and do not install in a sound sensitive environment (e.g. living room, bedroom, ...).

NOTES
- The above data is valid in free eld condition, because it is measured in a semi-anechoic room. If the
sound is measured under actual installation, the measured value will be higher due to environmental
noise and sound reections. Choose the installation location carefully and do not install the unit in a
sound sensitive environment (e.g. living room, bedroom, ...).
- dBA = A-weighted sound pressure level (A scale according to IEC).
- EW = entering water temperature - LW = Leaving water temperature
- Reference acoustic pressure 0dB = 20Pa
- Sound pressure level of low sound mode n°2 and n°3 is lower than n°1
