Automatic humidi cation/dehumidi cation algorithm
The humidi cation/dehumidi cation algorithm is used to inform the
master-supervisor of the humidi cation or dehumidi cation request in
the location where the terminal is installed.
If the humidity sensor is  tted (see par. 6.1.2) the terminal will be able to
activate the automatic humidi cation/dehumidi cation according to the
set point and the value read by the humidity sensor.
Automatic mode
In mode the heating/cooling request sees the following trend.
