WebAccess and its modules 

for ECL Comfort 200 / 300 

Application The WebAccess kit enables: 

The WebAccess unit with its remote control 

and data log provides an easy access to the 

ECL Comfort 200 / 300 controller by means of a 

standard Internet browser. 

It is possible to connect up to 4 ECL Comfort 

controllers to each WebAccess unit. It is also 

possible to connect up to 10 additional modules 

such as heat meters via LON as well as water and 

electrical meters with pulse output.

• Remote monitoring and control via Internet / 

Intranet 

• Configurable alarm settings and notification 

of external recipients via e-mail / SMS. 

• Data logging of sensor and reference 

temperatures 

The communication between the WebAccess 

unit and the ECL Comfort controller is based on 

the LonWorks® protocol. 

The WebAccess unit can be used for the ECL 

Cards P16, C14, C30, C37, C55, C62, C66, C75, F11, 

F66, and L10 in the ECL Comfort 200 / 300 series. 

Operating principles The WebAccess unit is a web server for the ECL 

Comfort 200 / 300 series. 

By inserting the ECA 82 LON module in the ECL 

Comfort 200 / 300 controller and connecting this 

to the WebAccess unit, it is possible to monitor, 

to log data and to control the ECL Comfort 200 / 

300 controller. 

All logged data are stored in the WebAccess unit. 

All LON nodes / components are set up by means 

of Plug and Play. No extra LON setup tools are 

required. 

No dedicated software is needed on the client’s 

PC.

Description The WAH pulse interface has 4 optically isolated 

digital inputs. The typical use of these inputs is 

to convert impulse signals to a value that can be 

stored in the WebAccess unit. 

Operation 

The data type can be configured to liters, kWh 

etc.
