NORDIS LYRA 5.14/5.21kW air-to-air heat pump, white, L18TC1, R32

The NORDIS LYRA L18TC1 is a modern and energy-efficient air-to-air heat pump designed for year-round heating, cooling, dehumidification and air circulation. The complete set includes a white wall-mounted indoor unit and an outdoor unit.
The nominal cooling capacity is 5.14 kW and the nominal heating capacity is 5.21 kW. The inverter compressor automatically adjusts output according to actual room demand, helping maintain a stable temperature while reducing unnecessary electricity consumption.
The unit operates in cooling mode at outdoor temperatures from -15 to +53 °C and in heating mode from -20 to +30 °C. Cooling efficiency is rated A++ with a SEER of 6.8, while heating efficiency in an average climate is rated A+ with a SCOP of 4.0.
AI 2.0 energy-saving technology automatically adapts operation to user habits and changing room conditions. Anti Direct Air Flow distributes air more evenly and reduces uncomfortable direct cold draughts.
Reverse Fan Blow runs the outdoor fan in the opposite direction to help remove dust from the heat exchanger surface. The I FEEL function measures temperature near the remote control and adjusts operation according to the user’s location.
The +8 °C maintenance mode protects unoccupied rooms against excessive cooling. Seven fan speeds provide precise airflow adjustment, while standard air filters support indoor air quality.
The white glossy indoor panel is designed for modern residential and commercial interiors. The minimum indoor sound pressure level for the L18TC1 model is 27 dB(A).
Remote Wi-Fi control requires an additionally integrated Wi-Fi module.
