Yamato R32 YD55T2T DC Inverter ducted air conditioner (three-phase)

Yamato ducted units use DC Inverter technology and R32 refrigerant, run quietly and cool efficiently even at -15°C, which makes them suitable for server rooms. They are Wi-Fi ready, have a silver-ion and activated-carbon filter, work on an unstable mains supply, and at only 245 mm high they fit discreetly into a false ceiling.

Features

Everything the unit does for you

  • Wi-Fi control

    The units can be controlled remotely over Wi-Fi. Through the Wi-Fi module built into the indoor unit, you can control the air conditioner from a distance with the dedicated app on a smart mobile device.

  • Condensate pump included

    Ducted units have a built-in condensate pump, so the water is lifted and drained up to 1,200 mm above the mounting position of the indoor unit.

  • Starts over a wide voltage range

    The units work normally even where the mains voltage is unstable or too low: from 176 V to 265 V for single-phase units, and from 304 V to 458 V for three-phase ones.

  • Auto-restart

    After a power cut, once the supply comes back, the air conditioner restarts automatically, keeping the settings it had before.

  • Self-diagnosis

    To make maintenance and servicing easier, if a fault occurs the error code is shown on the LED display of the indoor unit.

  • Eco mode

    In Eco mode, the unit reaches the temperature you set in the shortest time, then runs at a reduced frequency, holding the temperature while using less energy.

  • Timer

    You can program the unit to switch itself on or off, in the operating mode and at the temperature you want.

  • Sleep mode

    The function optimises how the unit runs while you sleep, by automatically adjusting the temperature curve, for greater comfort and lower energy use at the same time.

  • Intelligent pre-heating

    In heating mode, the indoor unit only starts blowing air once the evaporator has reached a temperature that avoids exposing you to a stream of cold air.

  • Safety lock

    The controls can be locked, so the settings cannot be changed by accident or by someone who should not change them.
