The parameters of the LON input configuration pictures can assume the values de-
scribed in the following.
This setting tells the ECL 2000 what is being measured by means of the LON sensor.
Value
Description
Outd. temp.
Outdoor temperature
Note:
When Outd. temp. is selected, the ECL 2000 uses the LON sensor to
measure outdoor temperature. Any outdoor temperature sensor connected
directly to the ECL 2000 (typically via sensor input S3) is disabled
Flow
Water flow
Wind velocity
Wind veloc.
Energy
Energy measurement. When Energy is selected, values for the accumu-
lated energy are automatically collected from the same device
None
The LON input is not used, i.e. no input is taken from the LON network
This parameter determines which circuit is influenced by the collected data.
Value
Description
None
No circuits affected
Circuit 1
Heat circuit 1
Circuit 2
Heat circuit 2
Hot water
Hot-water circuit
Circuit 1+2
Circuits 1 and 2
All circuits
All heat and hot-water circuits in the system
This parameter determines how often the ECL 2000 will poll the LON sensor.
Value
Description
X s
The number of seconds between sensor polls. For example, if Poll is set
to 25 s, the ECL 2000 reads the actual value from the sensor every 25
seconds
Poll can be set to values in the range 5 – 60 s for all sensor types. After
an external device has been polled 3 times without having anwered, this is
considered a sensor fault
