What is warm-up mode?

The HumidAir™ heated humidifier will rise to a target temperature of 40°C over 20 minutes. The device then holds this temperature for a further 10 minutes, ready for therapy to start. If therapy does not commence in that time, the device will automatically enter cool-down mode, where it will blow a small amount of air for around 20 minutes to stop condensation forming in the device.
