OPERATING MODE
3.1 AUTO MODE
This functioning mode involves the renewal of room air using the maximum flow rate of inflow and expulsion fans. In order to activate this procedure the user must press the
Mode/Select key on the interface panel until the “AUTO” icon appears.
The duration of this function depends on the Ct parameters (cleaning time) settable from the user interface panel of the machine. When this time expires, the system goes back
to the functioning mode that was set prior to the room cleaning procedure.
3.2 MANUAL MODE
This functioning mode involves the activations of inflow and expulsion fans according to the Po1 and Po2 parameters. In order to activate this procedure the user must press
the Mode/Select key on the interface panel until the “AUTO” and “AUX” icons appear.
The Po1 and Po2 parameters indicate a flow rate percentage (referred to the maximum of the installed fans) to be ensured in a one-hour functioning cycle. These parameters
can, therefore, be linked to the air renewal (moved air volume) that is to be ensured to the room.
The control will provide a constant functioning reference such as to ensure a constant instantaneous flow rate:
PISTx = Pox * PMAX
where
PISTx: inflow or expulsion instantaneous flow rate
Pox: it can be Po1 or Po2 depending on whether it is the inflow or expulsion fan
PMAX: maximum fan flow rate
3.3 AUX MODE
This functioning mode is entirely similar to manual mode, but allows the user to enable any resistive loads present in the machine for the anti-freeze function and production
of neutral air (the inflow air temperature must tend to that of the expelled air). In order to activate this procedure the user must press the Mode/Select key on the interface
panel until the “AUX” icon appears
