Who is the TXM42A for?
It is Daikin’s top wall-mounted range: very efficient and designed for air quality. As a guide, for a room of 25-35 m².
- Flash Streamer and a silver-ion filter, which according to Daikin break down allergens such as pollen.
- 2-zone motion sensor: sends the air away from people and switches to energy-saving mode when nobody is there.
- Built-in Wi-Fi with Daikin’s Onecta app.
- A++ for cooling (SEER 8.11) and A++ for heating (SCOP 5): it is a heat pump, so it also heats in winter.
- 21 dB(A) at its lowest speed.
