LON wiring 



Wiring to the ECL Comfort controller 

Step 1 

Mount the ECA 82 LON module 

in the ECL Comfort controller by 

dismounting cover plate B on the 

back of the ECL Comfort by means of 

a small slice cutter nipper. 

Step 2 

Mount the ECA 82 in the slides and 

press it gently into the connector on 

the ECL Comfort print board. 



Step 3 

Mount the new cover plate B, which 

is delivered with the option card. 

Pin connection ECA 82: 

1: LON data 1. Left side pin of the 

connector. 

2: Middle pin of the connector. Do 

not use! 

3: LON data 2. Right side pin of the 

connector. 

LON data 1 and 3 can be reversed. 

Pin connection WebAccess unit: 

1: LON data 1. Left side pin of the 

connector. 

2: LON data 2. Right side pin of the 

connector. 

LON data 1 and 2 can be reversed. 

Step 4 

Mount the LON connectors in the 

WebAccess unit and in the ECA 82 

module. 

LON termination 

Check that the termination jumper is 

mounted as ‘FT’.

LAN / Ethernet wiring 



Powering up 

When powering up the ECL Comfort controller, a period of about 30 seconds 

will elapse during which the database of the controller will be copied to 

the ECA 82 module. During this period it is not possible to contact the ECA 

82 module, neither from the ECL Comfort controller nor from the network. 

The start-up period will occur in connection with reset / powering up of the 

controller and ECA 82 module and also when the application is changed in 

the ECL Comfort controller. 

The WebAccess unit needs 2-3 min. to start up. During start-up, the status 

LED has a constant light. The unit is ready when the status LED starts flashing. 

Ethernet configuration 

First of all, the contact to the WebAccess unit must be established. This is 

achieved by means of a PC (Laptop / Notebook) and an xover Ethernet 

cable. 

Connect the Ethernet cable and configure your PC to the fixed IP addresses: 

IP: 192.168.1.32 

Subnet: 255.255.255.0 

Gateway: No 

Status LED 

Now the WebAccess unit can be contacted with the IP address 192.168.1.100 

via the Microsoft Internet Explorer. 

Remember to install the Adobe SVG Viewer before contacting the WebAccess 

unit. It can be downloaded for free from www.adobe.com. If you fail to install 

the Adobe SVG Viewer, you will not be able to see the application graphics. 



Configuration of ECL Comfort controllers 

Add the ECL Comfort applications to the WebAccess unit: 

Select menu option: Configuration / Units 

• Add ECL 

Click ‘Add’. State the ECL name for this menu location. If you already 

have set up alarm recipients, choose the one to be alerted in case of 

communication failure. Click ‘Continue’. 

Follow the instructions on the screen. 

• Edit ECL 

Click ‘Edit’. Edit the ECL name for this menu location. Choose alarm 

recipient in case of communication failure. Click ‘save’. 

• Remove ECL 

Click ‘Remove’ for the ECL you want to disconnect. Confirm the removal 

of the selected ECL by clicking ‘Remove’ once again. 



Configuration of modules 

Select menu option: Configuration / Units / Additional modules 

• Add 

Click ‘Add’. State the module name and choose under which ECL menu 

locations the module is to be shown. If you already have set up alarm 

recipients, choose the one to be alerted in case of communication 

failure. Click ‘Continue’. 

Follow the instructions on the screen. 

• Edit 

Click ‘Edit’. Edit the module name for this menu location. Choose alarm 

recipient in case of communication failure. Click ‘save’. 

• Remove 

Click ‘Remove’ for the module you want to disconnect. Confirm the 

removal of the selected module by clicking ‘Remove’ once again. 

When a new ECL unit or additional module is added, you might be asked 

to close your Internet browser and then restart it. This also applies if units 

/ additional modules have been changed or deleted when you close the 

dialog. This enables the Internet Explorer to show you the new / changed 

units / additional modules correctly. 



Configuration of input channels 

Heat meters: 

• No additional set-up is required. 

WAH pulse interface: 

• Select the ECL menu location under which the pulse interface is shown. 

• Select the menu option: Modules / ‘Menu label’. 

Click ‘Add’ and confirm use of licence. 

Click ‘Edit’. State the name / description, units (kWh or m3 ) and pulse 

factor. Also state the accumulated value of the meter (actual value 

displayed on the meter) and the max. possible value of the meter. 

WAH analog interface: 

• Select the ECL menu location under which the analog interface is shown. 

• Select the menu option: Modules / ‘Menu label’. 

Select the menu option: Modules / ‘Menu label’. 

Click ‘Add’ and confirm use of licence. 

Click ‘Edit’. State the name / description and units. Set the range of the 

input device by stating the min. / max. value that equals 0 and 10 V. 



IP configuration 

Set the IP address, subnet mask and standard gateway of the WebAccess data 

logger to comply with the relevant network. You can get these addresses 

from your network administrator or from your Internet supplier. 

When the IP address is changed, the WebAccess data logger restarts. After 

a period of 2-5 min. the Internet explorer should be restarted, and the 

WebAccess data logger can be found on the new IP address. 

It is extremely important to remember your IP address. Without this 

address, it will not be possible to access the data logger again. 



Light emitting diodes 

1. TP / FT-10 LON connection: Free topology / twisted pair 

2. Power supply: 8-24 V a.c. or 12-30 V d.c. 

3. RS 232 interface for PC connection 

4. Ethernet connection 

5. TP / FT-10 LON connection: Free topology / twisted pair 

6. Wireless 

• Constant light: Fatal error “no net”. 

It is not possible to get connected to the network (typically the SIM 

card is missing) 

• Slowly flashing light (½ Hz) : Connected to GSM “net found! 

• Fast flashing light (1 Hz): Connected to “dial up” 

7. Status 

• Constant light: The data logger is starting up and and there is no 

connection 

• Flashing light: The data logger is ready 

8. 100 Mb 

• Flashing light: Data are being trasmitted via the Ethernet 

9. Link 

• Constant light: The data logger is connected to the Ethernet 

10. Power 

• Constant light: The data logger is connected to the mains 

• No light: The power is disconnected 

11. Service (configuration of data logger) 

• Flashing light: The data logger is not configured
