2.4.3 Lon Module installation
In case of Lon connection with a BMS, there are two different modules available depending on the
physical connection to the customer network. The type of connection is FTT10.
A dedicated menu allows to properly setup the communication parameters.
3 Using the Controller
The control system consists of a unit controller (UC) equipped with a set of extension modules that
implement additional features. All boards communicate via an internal peripheral bus with the UC.
The UC continuously manages the information received from the various pressure and
temperature probes installed on the unit. The UC incorporates a program that controls the unit.
Two different types of UC HMI are available as standard HMI:
1. Inbuilt HMI (A/C units)
This HMI is provided of three buttons and one wheel button.
Alarm status (from any page it links with the page with alarm list, alarm log and alarm
snapshot if available)
INFO
Back to Main Page
ESC
Back to the previous level (it can be the Main Page)
Wheel
Button
Used to scroll between the different menu pages, settings and data available on the HMI
for the active password level. Rotating the wheel allows to navigate between lines on a
screen (page) and to increase and decrease changeable values when editing. Pushing
the wheel acts as an Enter Button and will jump from a link to the next set of parameters.
