• Independent SAF and EAF fl ow control: SAF and EAF are controlled each one by its respective
pressure transmitter signal. Two pressure transmitters are needed (supply and extraction).
The controller performs the conversion of the signal received from the pressure transmitter
to fl ow, using the relation
different for each model.
In case CAV mode is selected, in the Main screen it is showed the actual m
pressure transmitters and also a percentage of the maximum fan speed:
