PRODUCT IN COMPLIANCE WITH EU DIRECTIVE 2012/19/EU
The barred wheeled bin symbol appearing on the appliance or on its packaging
indicates that the product must be collected separately from other waste at
the end of its useful life.
The user must therefore deliver the decommissioned product to an appropriate
local facility for separate collection of electrotechnical and electronic
waste. Alternatively, the appliance to be scrapped can be delivered to the
dealer when purchasing a new equivalent appliance. Electronic products for
disposal measuring less than 25 cm can also be delivered free of charge to
electronic equipment dealers having a surface area of at least 400 m2 ,
without having to purchase other products. Proper separated collection of the
decommissioned appliance for its subsequent recycling, treatment and eco-
compatible disposal helps to prevent negative effects on the environment and
human health, besides encouraging reuse and/or recycling of its constituent
materials.

INSTALLING THE PRODUCT
The device detects the room temperature, therefore several factors should be taken into account when choosing an installation site. Position the device far from heat sources (radiators, sunlight, fireplaces, etc.) and from draughts, doorways and windows which could affect the temperature readings. It should be installed approximately 1.5 metres above the floor level.
WARNING!
Installation should be performed by a qualified technician. Before making any connections, shut off the electricity power supply to the heat generator via its external two-position switch. Install the product in a room with a normal level of pollution.
WALL INSTALLATION|
---|---
Connect the pair of wires to the terminal block to connect to the heat
generator via BUS| 
Fix the base plate contained in the installation kit to the wall| 
Position the ATAG NEOZ onto the base plate and push it delicately downwards.|
CONNECTION TO THE SYSTEM
The sending, receiving and decoding of signals occurs through the Bridge Net® BUS protocol, which puts the heat generator and the system interface into contact with each other
Connect a pair of wires to the BUS connector on the heat generator P.C.B.|
The electrical connection of the device is not polarized.
NOTE: IN ORDER TO AVOID INTERFERENCE PROBLEMS, USE A SHIELDED CABLE OR TWISTED PAIR CABLE.
NOTE 2: Connect only one system interface to the BUS network
INITIAL CONFIGURATION
WARNING!
To guarantee safety and correct operation of the system interface, it must be commissioned by a qualified technician in possession of the skills as required by law.
CONFIGURATION PROCEDURE
Initialization| Insert the system interface into the connection shoe by
pushing it gently downwards and making sure that the products are powered;
after a brief initialization, the device will be ready to be configured.
Selecting the language| The display screen shows “Language”. Select
the language by rotating the knob. Press OK to confirm
Selecting date and time| The display shows the “Time & Date”. Turn
the knob to select day, month and year. For each selection, press the knob to
confirm.
Once the date is set, the selection moves to setting the time.
Turn the knob to set the correct time; for each selection, press the knob to confirm.
Selecting the mode daylight saving time| Once the date is set, the selection moves to the daylight saving time setting. Turn the knob to select TIME PROGRAM or MANUAL.
If you want the system to automatically update the period when daylight sav- ing time is in use, select TIME PROGRAM. Press the knob to confirm.
Selecting the zones “Zones” Menu| This screen is used to select the
hydraulic zones to be displayed in the “Zones” user menu. Turn the knob to
select the zones in the system and press the knob to confirm.
Setting the “Zone” parameters| For devices compatible with this
function, you can set the following param- eters for the selected Zone:
- Operating mode: Manual/Programmed/Off;
- Zone Name (only for compatible devices);
- Room temperature Setpoint;
- Heating Controller (only for compatible devices) set the type of device associated with the zone being heated:
- none
- room sensor
- thermostat;
- Cooling Controller (only for compatible devices) set the type of device associated with the zone being cooled:
- none
- room sensor
- thermostat;
Selecting the zone| After, the display screen shows the selection of the zone to be assigned to the room temperature control device.
Turn the knob to select the desired zone. Press the knob to confirm. By as- signing zone no. 0 the device will exclusively carry out the function of system interface. After the zone selection, the system will repeat the initialization procedure
WARNING!
BUS ADDRESSING CONFLICT
After initialization, if the zone assigned to the device is already being used
by another device on the BUS network, an addressing conflict error message
will be displayed. Press the knob to access the configuration page of the
BridgeNet Bus network. Proceed with the correct addressing of the devices
according to the instructions in the respective manuals.
WARNING!
TIME SCHEDULING CONFLICT
A time scheduling conflict error is generated when one of the programmable
devices on the network does not support multi-level programming.
In this case, the programming must be set on “2 levels” through the 0.4.3.
parameter.
WARNING!
ROOM TEMPERATURE CORRECTION
In the event of installation on a wall-mounted Remote Modem (Light Gateway),
the room temperature measurement may require a correction.
