oor Unit ting D-A8 h tempera
Ind Hea HXH Hig For efficient hot water production and space heating• Air to water connection to VRV for applications such as bathrooms,sinks, underfloor heating, radiators and air handling units
• Leaving water temperature range from 25 to 80°C without electricheater
• "Free" heating and hot water production 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 hotwater tank
• 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 fullyintegrated with direct control over leaving water temperature
• Various control possibilities with weather dependant set point orthermostat control
• The indoor unit and domestic hot water tank can be stacked to savespace, or installed next to each other, if only limited height is available
• No gas connection or oil tank needed
• Connectable to VRV IV heat recovery

I. Definitions
Index definition of HXHD125A81) Index for selecting the piping and calculating the refrigerant charge and the total connection ratio� Index = 125 (see the installation manual and technical specifications drawing 3D097616)2) Index for calculating and selecting the unit capacity� Index depends on leaving water temperature � 125 (see below for details)
Selection procedure- Outdoor unit heating capacity (design point conditions) = HCo [kW] � See the heating capacity table of the outdoor unit
- Outdoor unit power input (design point conditions) = PIo [kW] � See the heating capacity table of the outdoor unit
- HXHD125A8 capacity calculation index = R � To be looked up (see table below)
- VRV DX + HXY indoor unit capacity index total = S � To be looked up (depends on the type of VRV DX indoor unit)
- Total indoor unit capacity index = index of connected VRV DX + HXY indoor units + HXHD125A8 capacity calculation index = S+R = J � To be calculated
- HXHD125A8 heating capacity (design point conditions) = HC [kW] � To be calculated
- HXHD125A8 power input (design point conditions) = PI [kW] � To be calculated
- HXHD125A8 cascade step power input = P [kW] � To be looked up
� HC = HCo / J * 112
Information� PI = PIo / J * R + P°: Total power input required to operate the cascade system = fraction of outdoor unit power input + HXHD* cascade step power input

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- (*) Does not occur simultanously on all sides.

Warning1.
2.See also the minimum and maximum allowed water flow range in the technical specifications.Water quality must be according to EU directive 98/83 EC.
HXHD200A* Indoor unit ESP curve
The ESP curves are the maximum ESP curves, with and without domestic hot water tank installed on top of the indoor unit (pump rpm: 4000).The pump of the indoor unit is inverter-controlled and functions to have a fixed T between the return water temperature and the leaving water temperature.In case of installing a domestic hot water tank, there is an additional pressure drop over the 3-way valve (delivered as an accessory with the tank).
Selecting a flow outside the operating area can damage the unit or cause the unit to malfunction.
