Use:

Split air/water heat pump with Inverter technology for heating individual housing or small service sector premises. Yuna II can be installed in new housing connected to one or two networks of low or medium temperature emitters (underfloor heating and cooling systems, fan coil type terminal units) and supply a domestic hot water heater (option).

• Wide operating range in both heating and cooling mode offers high performance in a wide temperature range.
• DC inverter twin-rotary compressors with Pulse Amplitude Modulation (PAM) and Pulse Width Modulation (PWM) provide enhanced reliability, low energy consumption and smooth vibration-free operation under all operating conditions.
• Variable-speed fans with an innovative patented fan blade shape ensure improved air distribution at exceptionally low noise levels.
• Pre-set or customised selection of the appropriate climate curve for stable output capacity to match the heat load.
• Output to link and integrate the unit with the existing heat  sources offers a dual-energy approach, increased savings and optimum comfort in all weather conditions.
• Able to control two independent comfort zones with a two‑zone kit added to the main comfort module.
• Leaving water temperature up to 60 °C for radiator and domestic hot water applications, making hot water readily available.
