3.1 Introduction
3.1.1 AFA4000/E
The AFA4000/E VAV Controller can be configured in the field to suit all applications, with
password-protected menus and diagnostic menus to aid installation and commissioning.
3.1.2 AFA4000/E/AS
The AFA4000/E/AS VAV Controller is integrated with the Auto Sash Controller. To set up the
Airflow controller, set the Auto Sash controller to Disabled, Disconnected or Not Configured to
ensure that the sash is under manual control whilst the AFA4000/E/AS airflow monitor is
commissioned. The AFA4000/E/AS auto-detects that the Auto Sash Controller is connected and
the Auto Sash menus and Operation status will not be displayed if the Auto sash is not
connected.
Note The Auto Sash can be used to provide a sash position signal to the AFA4000/E/AS when a
volumetric output is required from the AFA4000/E/AS .This should be set up once both
the AFA4000/E/AS and Auto Sash Controller have been set up and calibrated.
