EC3-751 Condenser Controller with LON Interface
Operating Instructions
GB
Electrical Installation
Refer to the electrical wiring diagram (below) for electrical connections. A copy of
this diagram is labeled on the controller. Use connection wires/cables suitable for
90°C operation (EN 60730-1). Ground the metal housing with a 6.3mm spade
connector.
Important:
Keep controller and sensor wiring well separated from mains wiring.
Minimum recommended distance 30mm..
Warning:
Use a class II category transformer for 24VAC power supply
(EN 60742). Do not ground the 24VAC lines. We recommend to use one
transformer per EC3 controller and to use separate transformers for 3
rd
party
controllers, to avoid possible interference or grounding problems in the power
supply. Connecting any EC3 inputs to mains voltage will permanently damage the
EC3.
Setup and Parameter Modification Using the Keypad of the ECD-000
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 Parameters modification below.

•
Press or to show the code of the parameter that has to 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 show...
"
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.
Neuron Id / Service Pin:
The service pin is available on ECD display and on the controller. It is only
needed, when using controller in a LON network.
•
Display:
Press the button for app. 1 second to send the Neuron ID. An LED (Service) in
the left upper corner will indicate the transmission of the Neuron ID.
•
Controller:
ECD-001
There is a small hole left of the network connector. Use a small pen or
screwdriver to press the switch behind the hole. An LED close to the switch will
light to indicate the transmission of the Neuron ID.
Load Default Parameters:
•
Use a small pen or screwdriver to press the service pin switch on the controller
and switch on the power supply on. The EC3-751 will be reset to its default
settings.
•
Special Functions:

Display of Data:
The data to be permanently shown on the display can be selected by the user (parameter
/1). In case of an alarm, the alarm code is displayed alternately with the selected data.
The user can inhibit the alarm code.
It is possible to temporarily display these values. This is a useful feature when
initially setting-up the system without the aid of the WebPages. Press the
SEL
button to scroll through all possible displayable data.. The display will show for one
second the numerical identifier of the data (see /1 parameter) and then the selected data.
After two minutes the display will return to the by parameter /1 selected data. This
action is only valid when parameter H2 = 3
