There are 4 physical Zone Input/Outputs which are used to control
Monodraught Natural Ventilation systems. They can be reconfigured via the
iNVent Configurator tool through the USB port to support other systems or
non-standard/new configurations. Each zone comprises of the following:
The Wall Actuator connection is used to control a Belimo actuator used
within Monodraught Ventsair systems or Window Actuator Control Units. The
terminals are wired for Ventsair units as follows, from left to right:
1.
0V DC
2.
2 - 10V Damper Control Signal
3.
2 - 10V Damper Position Feedback Signal
4.
2 - 10V Louvre Control Signal
5.
2 - 10V Louvre Position Feedback Signal
6.
24V DC Power

The Fireman’s Key Switch Input provides two volt-free contacts between
“COM” and “O” for open, and “COM” and “C” for close. When the “Open”
contact is closed, all dampers, louvres, wall louvres and windows will open.
When the “Close” contact is closed, all dampers, louvres, wall louvres and
windows will close. If both the “Open” and “Close” inputs are activated at the
same time by an external system, then the “Close” setting will take priority.
The system runs in normal mode when neither of the contacts are activated.
This is usually connected to a Monodraught 3-position Fire Key Switch.
The Competition Key Switch Input provides two volt-free contacts between
“COM” and “O” for open, and “COM” and “C” for close. When the “Open”
contact is closed, all dampers, louvres, wall louvres and windows will open.
When the “Close” contact is closed, all dampers, louvres, wall louvres and
windows will close to the competition mode setting between 5% and 20%
(default of 10%). If both the “Open” and “Close” inputs are activated at the
same time by an external system, then the “Close” setting will take priority.
The system runs in normal mode when neither of the contacts are activated.
This is usually connected to a Monodraught 3-position Competition Key Switch.
