4.2  System Overview

The System Overview is the ECL 2000’s main picture. When the ECL 2000 is
powered on, the System Overview appears in the display after the self-test has been
completed

1

. During normal operation, whenever no front panel push-button is

operated for a 10 minute period, the ECL 2000 automatically reverts to the System
Overview.

System Overview

Actual outdoor tempera-
ture

Actual hot-water temperature

Room temperature. If the plant has more than one heat
circuit, the room temperature is displayed individually
for each heat circuit.

24-hour program for all circuits. This 24-hour program
indicates that heat circuit 1 should be maintained at
comfort temperature from 06:00 to 12:00 and from
16:00 to 23:00. Outside these periods, the circuit is
maintained at night setback temperature. The hot water
is kept at comfort temperature constantly.

The System Overview shows the total setup of the plant. This means that the picture
looks slightly different, according to the application that was selected when the
controller was configured.

Timer

The heating system in this example consists of one heat circuit and one hot-water
circuit. In addition to these, the system also includes a timer, which you can see from
third line of the 24-hour program. When this function is enabled, a set of outputs on
the controller is used to switch on and off some external device, that is, the ECL 2000
is used as a timer to control this other device. See also page 33.

Display contrast

If the temperature in the room where the ECL 2000 is installed is very high, this may
affect the contrast of the controller’s LCD display.

1.

 

In the System Overview picture, use 

 and 

 to adjust the display

contrast.

See page 25 for information on what to do when powering on the ECL 2000 for the first time.
