Description
APPLICATION:
Power-controlled inverter air ; water heat pump for compact outdoor installation as monoblock design. Can be used for heating and hot water operation in the new building and the renovation due to high flow temperatures.
FEATURES/COMFORT:
Optimized noise reduction through enclosed cooling circuit and decoupled compressors. The evaporator's large leaf gap allows for low air resistance and, in conjunction with the modulating fan, provides a low sound power level. The combined steam/wet steam intermediate injection cools the scroll compressor at low outside temperatures and achieves a higher heating power/flow temperature. With integrated heat quantity and current counting via cold loop data. An emergency/additional heater enables monoenergetic operation.
EFFICIENCY:
The waste heat of the inverter is used for the return increase and increases the overall efficiency of the plant. Demand-dependant and energy-efficient circulation reversal defrosting. The condensate sump is heated by the cooling circuit to allow efficient defrosting.
INSTALLATION:
Integrated vibration decoupling for direct connection to the heating system. Swiveling electrical connection field for better accessibility. Quick access to the condensate tank through the cleaning opening on the back. The fan grillee, the handle shells and the cover are made of weatherproof and UV-resistant plastic in aluminum white.
