2.1.7 Enthalpy (optional)
It is possible to fit the ComfoAir with an enthalpy ex-
changer. An enthalpy exchanger helps to regulate hu-
midity levels in the dwelling. In addition to heat recovery,
the enthalpy exchanger also ensures moisture recovery.
Moisture recovery means that moisture from extracted air
is transferred to the supply air sourced from outside the
dwelling. An enthalpy exchanger is also less sensitive to
freezing.
2.1.8 Analogue input (0-10V)
The ComfoAir Luxe is fitted with one input (0-10V). This
input can be used to connect a sensor or control
system to the ComfoAir. Examples of the options include:
• CO2 sensor; flow regulation using carbon dioxide
levels;
• Moisture sensor; flow regulation using moisture le-
vels;
