The air handling unit will appear, press the button to select the air handling unit to pair it with the NaviPad. If there are
several air handling units at the same IP subnet, a list of available air handling units will be presented.
The IP address of NaviPad itself is presented above the Select device header
The Access system support up to nine air handling units being paired to one NaviPad, to be viewable in its system over-
view dashboard of the same network.
Note:
The use of a web browser to examine the air handling unit’s interface is supported with one web browser
together with two paired NaviPad. If that number of connection is exceeded, one or several of the following
will happen:
• periodically flashing red NaviPad button, despite no unacknowledged alarm.
• symbol telling no communication on NaviPad.
• red marked error fields for real-time values of the air handling unit user interface.
In systems with several air handling units monitored in a system dashboard, it’s recommended that this is done from
only one strategic placed NaviPad and let the other NaviPad on the same network only be paired with its own air han-
dling unit.
