For convenience, an infrared receiver for the optional IR remote control unit is
build-in, enabling quick and easy modification of the system parameters when a
computer interface is not available.
Alternatively, the parameters can be accessed via the 4-button keypad. The
configuration parameters are protected by a numerical password. The default
password is "12". To select the parameter configuration:
• Press the PRG button for more than 5 seconds; a flashing 0 is displayed
• Press or until 12 is displayed; (password)
• Press SEL to confirm password
• The first modifiable parameter code is displayed (/1).
• To modify parameters see "Parameter Modification" below.
P a r a m e t e r m o d i f i c a t i o n : p r o c e d u r e
• Press or to show the code of the parameter that must be changed;
• Press SEL to display the selected parameter value;
• Press or to increase or decrease the value;
• Press SEL to temporarily confirm the new value and display its code;
• Repeat the procedure from the beginning "press
To exit and save the new settings:
Press PRG to confirm the new values and exit the parameters modification
procedure.
To exit without modifying any parameter:
• Do not press any button for at least 60 seconds (TIME OUT).
• Press "ESC" on IR remote control.
T e m p o r a r y D i s p l a y o f D a t a :
It is possible to temporarily display the values of the different sensors. This is a useful
feature when initially setting-up the system without the aid of the WebPages. Press
the SEL sequentially. The value displayed on the screen corresponds to the number
corresponding to the /1 parameter. Action only valid when parameter H2 = 3
L o a d D e f a u l t P a r a m e t e r s :
The default parameter settings can be reloaded into the controller memory by using
the special function described below.
S p e c i a l F u n c t i o n s :
The Special Functions can be activated by:
• Press and together for more than 5 seconds. A flashing 0 is displayed.
• Press or until the password is displayed (default = 12). If password was
changed, select the new password.
• Press SEL to confirm password. A 0 is displayed and the Special Function mode
is activated.
• Press or to select the function. The number of special functions is dynamic
and controller dependent. See list below.
• Press SEL to activate the function without leaving the special function mode.
• Press PRG to activate the function and leave the special function mode.
Most of the Special Functions work in a toggle mode, the first call activates the
function, and the second call deactivates the function.
The indication of the function can only be displayed after exiting the special function
mode.
• 0: Display test function
• 1: Displays the current TCP/IP address
• 2: Set the controller TCP/IP address to the default value: 192.168.1.101
• 3: Resets all parameters to the factory default setting. The controller will
indicate "oF" during the reset.
The data to be shown on the display can be selected by the user. In case of an alarm,
the alarm code is displayed alternately with the selected data. The user can inhibit
the alarm code. Press the SEL button to scroll through all possible displayable data.
The display will show for one second the numerical identifier of the data and then
the selected data. After two minutes the display will return to the by parameter /1
selected data.

Er Data error
Data send to the display is out of range
M e s s a g e s
--- No data to display
The display will show an "---" at node start up and when no data is send to the
display.
In Reset to default values activated
The display will show an "In" when the factory default configuration data set is
initialized.
Id Wink request received
The display will show a flashing "Id" when the wink request was received. The
flashing "Id" will be shown on the display until the service button will be
pressed, or a 3 min delay timer will expire or a second wink request is received.
This function is action only when using SNMP protocol
OF Node is offline
The node is offline and no application is running. This is the result of a network
management command and will happen for example during node installation.
