Up to 12 Vento A50 units may be connected to a single SEA control panel
powered by the 40W power transformer AT-40, g. 20.
First connect the 12W transformer wire leads to the contacts A1:35, 36 of the
controller A1 (SEA) using the socket connector at the cable K2. The cable is
included into delivery set of the 40W transformer model.
Then connect the rst unit A3-No.1 to the contacts A1:11-15 of the controller
SEA using the connecting cable supplied with the rst unit. Connect the
second unit A3-No.2 (contacts A2: 21-25) to the rst unit (contacts A2: 11-15)
using the connecting cable supplied with the second unit.
Connect all the other units, up to 12 items, in the same way.
Connect power supply (230 V / 50 Hz or 120 V / 60 Hz, depending on the unit
model) to the contacts A2: 31,32 of each unit.
The fan impeller rotation direction is determined by position of the jumper
JMP1 on the PCB of A2 unit: the leftmost position sets the unit to extract mode
(Flow Out) and the rightmost position sets the unit to supply mode (Flow In).
The jumper is used to set direction for each fan in the group. The transformer
unit is connected to power mains through the power cable with a plug, which
is prewired to the transformer unit terminal block by the manufacturer.
