Climate Control

Climate Control is an intelligent system that controls the humidifier and the ClimateLineAir heated
air tubing to deliver constant, comfortable temperature and humidity levels during therapy.
Designed to prevent dryness of the nose and mouth, it maintains the set temperature and relative
humidity during sleep. Climate Control can be set to either Auto or Manual and is only available
when the ClimateLineAir and the HumidAir humidifier are attached.

Climate Control Auto

Climate Control Auto is the recommended and default setting. Climate Control Auto is designed to
make therapy as easy as possible, so there is no need to change the temperature or humidity
settings.
The Tube Temperature is set to 27°C and Climate Control adjusts the humidifier output to maintain a
constant, comfortable humidity level of 85% relative humidity while protecting against rainout
(water droplets in the air tubing and mask).

Climate Control Manual

Designed to offer more flexibility and control over settings, Climate Control Manual lets the patient
adjust the temperature and humidity to the setting which is most comfortable for them.
In Climate Control Manual, the Tube Temperature and the Humidity Level can be set independently
however, rainout protection is not guaranteed. If rainout does occur, first try increasing the tube
temperature. If the air temperature becomes too warm and rainout continues, try decreasing the
humidity.
Tube Temperature
If the air in the mask feels too warm or too cold, the patient can adjust the temperature to find what
is most comfortable or turn it off completely. The Tube Temperature can be set to anywhere
between 16–30°C.
The temperature sensor located at the mask end of the ClimateLineAir heated air tubing enables the
system to automatically control the temperature of the air delivered to the patient. This ensures the
temperature of the air delivered to the patient does not fall below the set minimum temperature,
therefore maximising breathing comfort for the patient.
Humidity Level
The humidifier moistens the air and is designed to make therapy more comfortable. If the patient is
getting a dry nose or mouth, turn up the humidity. If the patient is getting moisture in their mask,
turn down the humidity.
The Humidity Level can be set to Off or between 1 and 8, where 1 is the lowest humidity setting
and 8 is the highest humidity setting.
For each humidifier setting, the Climate Control system delivers a constant amount of water vapour,
or absolute humidity (AH), to the patient's upper airway.
Automatic adjustment
The humidifier and ClimateLineAir heated air tubing are controlled by the Climate Control algorithm
to deliver constant humidity and temperature outputs. The system adjusts automatically to changes
in:

ambient room temperature and humidity values

flow due to pressure changes

flow due to mask or mouth leak.
