System operating and monitoring

There are 3 ways to operate and monitor the system:
- Via NEA SMART 2.0 App
- Via integrated webpages (only when user is in the building itself)
- Directly via the Room Units
4.8.1

Using the room units

Room units can be used for:
- Changing actual set point (temporary)
- Changing set points for NORMAL and REDUCED energy level of
actual operating mode (permanent)
- Change between energy levels NORMAL, REDUCED and STANDBY
- Activation of TIMER or PARTY mode
- Display and confirm messages (open window, condensation
problem, error code)
To avoid unwanted or inadmissible settings, minimum
and maximum values for set points can be defined.
Additionally, the buttons of the Room Units can be locked.
For public areas, the remote Room Probes can be used which
look identical to the room units but have no display or operating
buttons.
4.8.2

Integrated web pages

The NEA SMART 2.0 Base has an integrated web server, with web
pages in 15 languages.
The web pages can be accessed by WLAN or LAN with any device by
inside the house.
a web browser
The web pages can be used by the
system, check functionalities and modify important parameters.

4.8.3 Installer only web pages – Commissioning wizard for
global system set-up
To facilitate an easy, quick and reliable commissioning process, the
system has got a built in wizard which guides the installer through the
setup.
The wizard ensures, that
- all installed system components are detected and the system can
access them
- all physical and logical connections between components and any
external devices are checked and work correctly
- relevant settings and parameters are customised to the installation
Installations with only a single NEA SMART 2.0 Base
station and one R-Module, the system can be initiated
without using the wizard.
However, the following limitations will apply:
- the system can only control room temperatures
- only heating mode is possible
- Timing programs cannot be used (system date and time is not
set)
It is recommended to always use the wizard.
Pre-requisites for running the wizard:
- Hardware installation completed
- All communication bus connections are made and checked
- Room Units, Room Probes and outside temperature sensors are
paired
It is highly recommended to have all devices, such as pumps, actuators,
boiler, chiller, dehumidifiers fully connected to the system to enable
complete testing of all connections and functions.
All probes such as external and flow temperature ones
are deemed essential and must be connected for the
wizard to complete its program.
To run the Wizard, the Master Base, is set to access point mode (point
to point connection to one device only).
The system master is defined by the system bus
address setting 0000.
It is possible, to connect by LAN or WLAN, in most cases a smart
phone, tablet or laptop is used, connected by WLAN.
For details how to connect see chapter 7 System set up.
