The wizard starts automatically when an unconfigured
NEA SMART 2.0 system is switched on.
The commissioning wizard checks for consistency at preset
point within the commissioning process and holds the process
or prevents the system from starting up if the connected
components do not match the entered configuration.
Main steps in wizard:
- Selection of language, type of installation, building type and energy
standard. System date and time is taken from the connected smart
device
- Definition of connected devices, functions and number of manifolds
and rooms
- Automatic verification if desired functions are achievable within the
defined hardware environment
- Scanning and verification of components connected to the commu-
nication bus
- Parameterisation of all U-Modules (control of mixed circuit, dehumi-
dification control)
- check of all the used inputs and outputs of U-Modules
- Definition of rooms and their operating modes (heating/cooling),
connection to manifolds
- Definition of input and output signals of Base(s) and R-Modules
- Final verification check if all desired functions are possible and
activation of the system
4.8.4 Installer only web pages – Room setup and
parametrization
After successfully completing the commissioning wizard, an installer
can assign room names, select from a range of extra options for the
rooms (assign pilot role, enable auto start function), modify and
allocated timer programs.
The installer only web pages also give access to a selection of
parameters. The complete set of parameters can be accessed via

NEA SMART 2.0 App.

Room management and certain settings are accessible
in user level, but with some restrictions.

User Web pages

The user may operate the system via integrated web
pages if he does not want to connect his system to a
cloud and to use the NEA SMART 2.0 App.
In this case a tablet permanently connected to the NEA SMART
2.0 Master Base is the recommended solution.
Main functions:
- Select energy level for entire installation or for each room individually
(NORMAL, REDUCED, HOLIDAY / ABSENCE)
- Select operating mode (heating manual, only heating, cooling
manual, only cooling, automatic mode)
- Select PARTY mode
- Monitor actual room temperatures and humidity
- Define room temperature set points for above named operating
modes and energy levels
- Change temporary room temperature set points
- Edit timing programs and assign them to rooms and dehumidifiers
- Define heating and cooling period
- Modify starting points for heating / cooling mode
- Define minimum / maximum values for floor temperature
- Manage access to cloud via router
4.8.6 NEA SMART 2.0 App
To use the NEA SMART 2.0 App, it is necessary to connect the Base
(only the system master) to a router and to establish the connection to
the cloud.
The NEA SMART 2.0 App is not only the most comfortable way for the
user, to operate and monitor his system, it is also the most powerful
tool for installers and service engineers, to analyse the behaviour of
the system, optimize it and detect potential problems.
The app offers – beside all above listed features of the web pages – the
additional functions:
following
- Easy and intuitive operation of the system independent of location
- Automatic activation and deactivation of reduced energy level by
locating user and identifying his distance to his home (geofencing)
- HOLIDAY function with calendar
- Statistics of room temperatures, humidity and heating / cooling
behaviour
- Tips for optimization potential and recommended maintenance
actions
- Remote diagnostic by service engineers (when this is activated)
- Advanced setting and parametrization

Warnings and alarm functions

The warning or alarms listed below are displayed on the room unit via
a symbol or error code:
- Open window detected
- Risk of condensation
- Low battery of wireless Room Units
