Operating Guide

5.3 Flow temperature

The ECL Comfort 210 / 296 / 310 controls the DHW temperature
according to the desired flow temperature for example under the
influence of the return temperature.
The desired DHW temperature is set in the overview display.
50.3: Actual DHW temperature
50: Desired DHW temperature
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.
External signal for desired flow temperature
A voltage (0 - 10 V) can be applied to the input terminal S12 in
order to determine the desired flow temperature.
The measured voltage on input S12 must be converted to a
temperature value by the controller. When the voltage gets higher,
the desired flow temperature increases.
The following settings set up the scaling.

Push the dial to see the graph and enter the value sets for the input
voltage (1 and 10 volt) and displayed desired flow temperature.
Desired flow temperature:
Fixed voltage settings:
Factory settings:
This means that the 'Desired flow temperature' is 10 °C at 1.0 V
and 100 °C at 10 V.
Typically, the higher the voltage, the higher the displayed desired
flow temperature.

This example shows that 1 volt corresponds to 10.0 °C and 10 volt
correspond to 100 °C.
The external voltage signal must be higher than 1.0 V in order to
activate the override.
