Rêve 237R H2O
  • Cooling only and heat pump
    air conditoner +  water radiator 
  • Water-cooled
  • To be freely installed: not necessarily on a  perimetral wall, without holes in the wall
  • Very high energy efficiency
  • Very low energy consumption
  • External sound level lower than the air-cooled version
  • Ozone friendly refrigerant: R410A
  • Packaged double-duct straight cooling and heat pump air-conditioner + water radiator (with optional joint kit for connection to the heating plant)
  • Water-cooled condensation with a water medium consumption of about 1  m3 for a 8 hour operation.
  • To be freely installed, not necessarily on a perimetral wall, because no holes in the wall are requested.
  • Designed to operate with both town water and wellwater or groundwater; it can be used also as terminal unit of a closed circuit system (water loop) with water at 30°C, according to EN14511 standard specifications.
  • High efficiency spiral heat exchanger.
  • Solenoid valve to stop the town water flowrate when the compressor is off.
  • Anti-freeze protection on the condensation water circuit.
  • It's suggested the installation of a filter to be inspected on the entry of the town water (by the installer).
  • Automatic change-over between cooling and heating modes.
  • Infrared remote control with 24h digital timer .
  • Double temperature sensor (on the unit and inside the remote control); double temperature indication (set and room).
  • Dry only function.
  • Ventilation only function.
  • "I Feel" feature, granting the best comfort conditions.
  • "Sleep" feature, with automatic adaptation to the night temmperatures.
  • Horizontal flap swinging or to be set to a fixed position by remote control.
  • Vertical flap by manual control.
  • Anti-mould and anti-bacteria washable filters.
  • Three-speed tangential fan with auto or speed manual selection.
  • "Cold Draft Prevention" device with water temperature < 40°C in water radiator mode and with evaporator temperature < 40°C
  • High precision thermostat with adjustment from 6°C to 40°C in water radiator mode.
  • Heating function disabled during defrosting cycle.
  • Auto restart after a black out, saving all feature parameters set before the power failure.
  • Electronic protection against over-pressures.
  • Optional joint kit for hydraulic connection to the heating plant (with three-way bypass valve included) necessary only in water radiator mode.
  • Special optional support kit of two small feet for floor installations (glass walls, etc.).
  • HFC refrigerant R410A.
  • High efficiency rotary compressor.
