7.15.5 Humidity control
Humidifi cation
The control logic for humidity control with probe is shown in the fi gure. When the humidity falls below the humidity set point
Sth plus the humidity diff erential rdH, the humidifi cation output is activated.

Notice: parameter F4r is used to decide whether or not to disable the humidifi cation output during defrosts:
• F4r=0 -> humidifi cation output active based on humidity control;
• F4r=1 -> humidifi cation output disabled during defrosts, regardless of the request.
Notice: the humidifi cation output is always deactivated in the event of an alarm that stops the compressor immediately.
Examples:
• Alarm CHt;
• Alarm IA (when A6 = 0).
Dehumidifi cation
For humidity control with probe, the dehumidifi cation function can also be managed. The control logic is shown in the fi gure.
When the humidity rises above the humidity set point Sth plus the Dehumidification control differential rrh, the dehumidifi ca-
tion output is activated.
