Control logics
Cooling mode (fan coil)
By means of the remote control it is possible to set the cooling mode and set an operating
temperature. If the fan speed is set in automatic mode the system selects the fan speed for itself
and decides the opening of the water valve depending on the difference between the operating
temperature set by the user (setting) and the temperature measured by the ambient probe.
