5.2 Distribution system
5.2.1 Atomisation system solenoid valve management
To manage the distribution system, the zone panel controls the following solenoid valves:
• distribution manifold ll/drain (normally closed NC / normally open NO, respectively). See the following diagrams;
• vent, used to facilitate the emptying of the distribution system (NOV, normally open);
Case 1: installation in an AHU (air handling unit)
• The water is atomised through a series of distribution manifolds (racks), equipped with nozzles.
• One or more manifolds can be grouped together to form a “step”. All of the manifolds in the same step are activated simulta-
neously to start/stop atomisation.
• Each rack can be managed by a zone panel. There are a maximum of 6 steps per rack.
• Each step comprises a maximum number of solenoid valves, as shown in the table; however the total number of powered
solenoid valves cannot exceed 22 (including the vent and line drain valves).

6 1 NC + 1 NO
Tab. 5.b
(*) NC1a, NC1b, ..., NC1e +NO1a, NO1b, ..., NO1e
Case 2: installation of the blowers in the room
The water is atomised through the nozzles installed on blowers or on racks in the room. These can be grouped together to form
steps, in the same way as for the rack manifolds.
5.2.2 Drain valve management (NOL)
The zone panel manages and controls the line drain valve (NOL, normally open).
Notice: the line drain valve must be tted at the lowest point in the water circuit and wired to the nearest electrical pan-
el (pumping station or zone panel), so that when opened, the entire system is emptied.
Case 1: Pumping station located below the distribution manifolds
Connect the drain valve near the zone panel that will control its opening.
Case 2: Pumping station located above the distribution manifolds, placed at dierent heights.
The drain valve must be connected near to the lowest distribution manifold.
Notice: the control signal for the zone 12 drain valve is output J12 NO3 on the zone electrical panel controller. See the
corresponding manual.
Case 3: Distribution manifolds located both above and below the pumping station
Connect multiple drain valves at the lowest points in the water circuit.
