1 Introduction

This LON option is based on Echelons LonWorks.

The following instruction describes the parameters that can be communicated be-

tween a LonWorks network and ECL Comfort. The build-up of the physical network

is not described.

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.

2 Getting started

The LON option can be used together with ECL Comfort 200 and 300. It is not pos-

sible to use the LON option on ECL Comfort 100.

To enable LON option operation, the system data must be entered in ECL Comfort.

Further information on the operation of ECL Comfort is contained in the instruction

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 the LON option card in the slides and press it gently into the connector on the

ECL print board.

Step 3:

Mount the new cover plate B, which is delivered with the option card.

Pin connection:

• 1: LON data

• 2: Ground

• 3: LON data.

2.2 Starting up

When starting up the LON option, a period of about 30 seconds will elapse during

which the database from the regulator will be entered. During this starting up period

it is not possible to come into contact with the LON option, neither from ECL Com-

fort nor from the network. The starting-up period will occur on the reset/power up

regulator/LON option, and when an application change is made in ECL Comfort.

After starting up, the following parameters can be activated via the ECL Comfort

MMI interface:

• Parameter 196 in circuit 1 is the service pin.

• Parameter 197 in circuit 1 is the LON option reset.

Scrolling down through the parameters on the installer page (grey page) with the ar-

row keys can access parameter 196 and 197.

The parameters can be activated/deactivated with the +/- keys (see instructions).

At wink, the display will flash until any key on ECL Comfort is pressed.

When updating parameters in ECL Comfort the values must bee in a workable range.

If they fall outside the range, they will be rejected.

2.3 XIF file

The XIF file can be found on the Danfoss intranet.

Before ordering check out the software version in the LON option. The software ver-

sion can be read directly on the memory IC on the LON option card. Software ver-

sion can also be found using the network in parameter nviParamCmd/nvoParamResp,

selector 1000.

4.1 Mandatory network variables

General for mandatory and optional network values:

Values set from the network can also be changed in the regulator itself. Thus the

last-stored change applies, independent of whether the setting comes from LON or

from the regulator. The valid range is set via the MMI list. The specification below

gives the normal range.

Transmission

A value can be set in Sensor update (preset 1001) to indicate how often the sensor is

to be read. If the measured value during the period changes more than the value set in

the temp. step (preset 1004) the network is updated. Measured values are always up-

dated in accordance with the time set in SendHeartbeat (preset 1002) irrespective of

whether they have been changed.

The temperature step can be varied from 1/128°C to 255/128°C.

Updating speed

Sensor update takes a minimum of 5 s

Maximum 65000 s

Factory setting = 300 s

SendHeartbeat takes a minimum of 5 s

Maximum 65000 s

Factory setting = 600 s
