Humidity Control - Daikin UATYA-BBAY1 Mode D'emploi

5.4 humidity control

Humidity control devices are managed according to the value measured by the reference probe. The measured value
is compared with the desired value (setpoint), after which the system calculates the difference between these values
and then enables the most suitable devices based on this difference.
The proportional band identifies the control range of the air conditioner system and it is set up with the same values
for both humidification and de-humidification.
The dead zone identifies the range around the setpoint within which the devices are not enabled (it is used to prevent
oscillations in the setup value).
The diagram below shows the behaviour of humidification and de-humidification devices.
The parameters involved are shown in the table.
