Instructions ECA 82 LonWorks in the ECL Comfort 300/301
1 Introduction
1.1 Scope
This ECA 82 option for ECL Comfort is based on Echelons® LonWorks®. The ECA 82 can be used in ECL Comfort
300/301 series. In the remaining part of these instructions, the type designation ECL Comfort will be used.
1.2 About the implementation in the LonWorks protocol
The following instruction describes the parameters that can be communicated between a LonWorks network
and ECL Comfort. The build-up of the physical network is not described. For further information see Echelons
homepage: http://www.echelon.com/.
The instruction is divided into three main sections:
1. The LonMark node object is used to the extent that functions are supported in ECL Comfort. The
functions from the node object that are supported in ECL Comfort are described in “Node object”.
2. The basic parameters behind weather compensation are described separately in the section on the
weather compensator object.
3. Parameters that are special for ECL Comfort are described separately in the manufacture-defined
section.
1.3 General information
1. The possibilities for communication depend on the application loaded in the ECL Comfort. This ECA
82 is designed to fit all ECL Comfort 300/301 application cards. Hardware configuration settings and
future parameters might not be supported.
2. Only one kind of communication can be used in the ECL Comfort. It is not possible to run RS232
together with ECA 82 communication.
1.4 ECA 82 compatibility with other optional modules
ECA 71 ECA 73 ECA 80 ECA 81 ECA 83 ECA 84 ECA 86 ECA 87 ECA 88
No No Yes No Yes No Yes No Yes
1.5 ECA 82 compatibility with the ECL Comfort controller and applications
ECA 82 is fully compatible with ECL Comfort controllers 300/301 as of version 1.11. Older ECL Comfort controllers
versions are also compatible with ECA 82 but in some cases with limited functionality.

Instructions ECA 82 LonWorks in the ECL Comfort 300/301
2 Getting started
The ECA 82 can be used together with ECL Comfort 300 and 301. It is not possible to use the ECA 82 together
with ECL Comfort 100/110/200.
Further information on the operation of ECL Comfort is comprised by the instructions supplied with the ECL
Card.
2.1 Installation
Step 1:
Dismount cover plate B on the back of the ECL Comfort using a small slice cutter nipper.
Step 2:
Mount 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:
• 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.
The FTT10 transceiver is based on a balanced bus. LON data 1 and 2 can be reversed.
2.2 Starting up
When starting up the ECA 82, a period of about 30 seconds will elapse during which the database from the
controller will be copied. During this starting up period it is not possible to come into contact with the ECA 82,
neither from ECL Comfort nor from the network. The starting-up period will occur on the reset/power up of the
controller/ECA 82, and when an application change is made in ECL Comfort.
After starting up, the following parameters can be activated via the ECL Comfort user interface:
• Line196incircuitIistheservicepin.
• Line197incircuitIistheECA82reset.
Lines 196 and 197 can be can accessed by scrolling down through the lines on the installer page (grey page) with
the arrow down key.
The lines can be activated/deactivated with the +/- keys (see the instructions for the application card).
At wink command, the display will flash until any key on ECL Comfort is pressed.
2.3 Service pin and neuron ID
The ECA 82 does not have any hardware service pin. The service pin is activated from the ECA 82 software
application. This means that it is not possible to send any service pin if the ECA 82 is put in non-configured
mode. If the ECA 82 anyhow is set in non-configured mode, the unique neuron ID number is required to set
the ECA 82 back in configured mode. If the ECA 82 is decommissioned or non-configured without having the
neuronID,theECA82isdamaged!ThesystemintegratorisresponsibleformakinganoteoftheneuronID.

2.4 XIF file and program ID
The XIF file can be found on the internet.
Before using a XIF file, check the software version in the ECA 82. The software version can be read directly on
the memory IC on the ECA 82 card, see Figure 1 and Table 1. The Software version can also be found using the
network in parameter nviParamCmd/nvoParamResp, selector 1000, see 5.3.10.1 Software version in ECA 82.
When using the ECA 82, a XIF file which fits the software version is required.

¹) Can only be activated if the controller is set in manual mode by the network or controller user interface.
²) If the controller is parked in line B at the user’s side (yellow), the valve and pump status is overridden by the controller, in order to
give the locally positioned user a possibility manually to override the controller user interface. The override from the controller
user interface can be avoided in ECL Comfort 300 by removing the ECL card from the controller. Without the ECL card the controller
will lock the keyboard after 5 minutes. Line B on the user’s side is designed to secure that a manual control can be carried out
locally directly without distortions from the network.

This input is only active in an ECL Comfort without a pulse input. If a pulse module is connected, the actual
power information is delivered as pulses. The ECL Comfort is limited to one type of input flow/energy at each
circuit.
When an update occurs on this input, some extra parameters will expire in the ECL Comfort service parameters
list (grey side of the application card).
Lines 110 - 115 expire in the controller user interface.
Line 114 has to be set to 1.
Line 115 has to be setup on the controller user interface in order to choose how the power is displayed in the
controller user interface.

Table 11: Configuration of ECL Comfort flow / energy input
4.8.1 Setting time constants
When the ECL Comfort CPU receives flow/ energy data, it will apply some filtering to the received data. Limiting
of flow/energy consumption takes place by integral control. For both these processes, i.e. the filtering of the
received data and the integral control, the ECL Comfort needs a time constant. These time constants are
determined by lines 113 and 112, respectively.
Lines 112 and 113 can be set for circuit I as well as circuit II. When setting the lines, you change between circuits I
and II by pressing the circuit I/II button.

Line Range Default value Description
112 1 – 250 40 Line 112 is a time constant for integral control of flow/energy limiting. A high value of
112 means fast control, a low value means slow (more stable) control
113 1 – 250 2 Line 113 is a time constant for digital filtering of flow/energy input data. When line 113
is set to 1, no filtering is applied. A high value of 113 means that a degree of filtering
applied
Table 12: Adjustment of time constants
4.8.2 Setting the flow or energy reference
Before the ECL Comfort can perform flow/energy limitation, a reference flow or energy value must be entered
for each circuit where flow/energy limitation should be active. The flow/energy reference value works differently
for a heating circuit as for a domestic hot-water circuit.
Heating circuit:
For a heating circuit (circuit I or II in the ECL Comfort), the flow/energy reference is determined indirectly by the
ECL Comfort in accordance with the actual outdoor temperature. For a heating circuit the ECL Comfort thus
performs outdoor temperature dependent flow/energy limitation. The ECL Comfort Installer’s Guide (‘grey’
section, Service Parameters) describes the functions and set-up of return temperature limiting in a heating
circuit. Flow/energy limitation works according to the same principle. The flow/energy reference is determined
according to an outdoor temperature curve:
Desired flow / energy
Line 116
Line 117
Outdoor temp.
-15 0 +15
Figure 4: Principle of the flow/energy limitation
The maximum and minimum of the curve shown in Figure 4 are determined by the lines 116 and 117,
respectively. The corresponding x-coordinates are identical to the x-coordinates of the return temperature
limitation curve. See the ECL Comfort Installer’s Guide on how to read and write the x-coordinates.
Line Range Default value Description
116 * 2999 Line 116 is the maximum y-coordinate of the flow/ energy limiting curve
117 * 2999 Line 117 is the minimum y-coordinate of the flow/ energy limiting curve
Table 13: Flow/energy limitation
For a domestic hot-water circuit, the flow/energy reference is entered directly into line 111.

4.11 General handling of outdoor temperature input
In order to use this input for weather compensation in the ECL Comfort, no physical outdoor sensor can be
connected. If a physical sensor is mounted, the outdoor temperature input will come from the ECL controller.
The physical sensor always has the highest priority.
The ECL Comfort must act as a slave (no outdoor sensor connected) in order to use outdoor sensor values from
the network. This influences the possibility of combining the controller with other remote controllers: ECA 60,
ECA 61 and ECA 63.
The connection can be verified: Outdoor temperature is shown in the controller display at the user side, line A,
bottom left.
