1 Introduction
Scope
This ECA 82 option for ECL Comfort is based on Echelons® LONworks®.
The ECA 82 can be used in ECL Comfort 200 and 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 applications card. 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 ECA82 communication.

•
¹) Sensor 6 cannot be shown if applications card <= CI05.
• ²) Only one room temperature sensor can be shown on the LON network.
• Card index 08 (CI08) requires ECL version 1.08 or 1.09, otherwise a CI05 is loaded.
• Updating ECA 82 from version 1.6 to 1.7 causes an error:
The error prevents writing some of parameters from the LON interface to the ECL
Comfort.
• ECA 82 version 1.8 only exists in test samples.

2 Getting started
The ECA 82 can be used together with ECL Comfort 200, 300 and 301. It is not
possible to use the ECA 82 together with ECL Comfort 100.
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.
DH-SMT VI.7F.C4.02 @ Danfoss 12/2004 Page 7 of 48
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 noting
down the neuron ID.

2.4 XIF file
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
Using the ECA 82 requires a XIF file which fits the software version.

The XIF file can also be loaded directly from the ECA 82 via the LON network for
example by using the LONMaker for Windows.

!
¹) Can only be activated if the controller is set in manual mode by the network or controller
user interface.
!
²) Note: 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.
3.1.2 3. Setting time and date: Input
network input SNVT_time_stamp nviTimeset;
The actual time and date entered in the ECL can be set here.

Other values are not supported.
Relays placed on options cards (ECA 80 & ECA 86) cannot be controlled from the ECA
82. The application in ECL Comfort always control options relays.
!
Note: The pumps can only be controlled if the controller is in manual mode.
Manual mode (for all circuits) can be entered in nviRequest, see 3.1.1.1. Node request:
Input page 9 or directly at the ECL Comfort.
In some applications the ECL Comfort overwrites the specified setting from the
network. In sequence controllers (C75) non-valid relay combinations is overwritten by
the ECL Comfort. Do not use this override function in the applications F05 and F06.

Field ascii[0] - ascii[29] must contain the value 0x00;
Field ascii[30] must contain an value indicating which week plan to report.

Field ascii[30] value Week plan area
0x10 Week days in circuit I
0x11 Weekend in circuit I
0x20 Week days in circuit II
0x21 Weekend in circuit II and all days circuit III
The week plan is divided into ½ hour intervals. The week plan can contain a maximum
of 3 periods a day. Each field ascii[0] - [29] is a char build of 8 bit. Each of these bit
represent ½ hour in the week plan. The exact position can be found using Table 10.

watt. (Max value in the ECL Comfort display).
Actual energy input can be delivered for circuit I and II. The input can be used in
controller for energy limitation.
See 4.8 for details setting up the ECL Comfort for energy input.

Input unit = liter / second.
Valid range 0 .. 833 liter / second (0..2999 m

The actual flow input can be delivered for circuit I and II. The input can be used in
controller for flow limitation.
See 4.8 for details setting up the ECL Comfort for flow input.
4.8 Handling energy and flow input 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.
