The advanced touchscreen controller supports 23 languages, including Chinese, English, German, Spanish, French, Italian, Dutch, Polish, Czech, Slovak, Slovenian, Danish, Norwegian, Swedish, Russian, Turkish, Bosnian, Ukrainian, Greek, Romanian, Serbian, Bulgarian and Hungarian. With an intuitive interface and intelligent temperature management, it enables convenient control of heating, cooling and domestic hot water functions, providing a user-friendly experience for customers worldwide.
Site Preparation & Unit Placement
Choose a well-ventilated outdoor location with enough space for air inlet, air outlet and maintenance access. Place the R290 inverter air source heat pump on a flat concrete base or anti-vibration bracket. Keep the unit stable, level and away from enclosed or poorly ventilated areas.
Water Pipe Connection
Connect the heat pump to the buffer tank, domestic hot water tank, floor heating, radiators or fan coil system according to the project design. Make sure the water inlet and outlet are connected correctly. Pipe insulation is recommended to reduce heat loss and improve heating efficiency.
