Operating Guide ECL Comfort 210/296/310, application A230
External signal for desired flow temperature (A230.2 and
A230.4):
A voltage (0 - 10 V) can be applied to the input terminal S8 in order
to determine the desired flow temperature.
The measured voltage on input S8 is 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.

The remotely set value for the desired flow temperature is indicated by the
unit °C.
Push the dial to see the graph. Turn the dial to enter the desired
flow temperature value for the input voltages (fixed values) at
1 and 10 volt.
Factory settings are different in A230.2 and A230.4
The applied voltage signal must be 1 Volt as a minimum.
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.

Example: Relationship between input voltage and displayed value for the
desired flow temperature
Desired flow temp. (°C)
This example shows that 1 volt corresponds to 10.0 °C and 10 volt
correspond to 100.0 °C.
A230.2
A value for the desired flow temperature is indicated only when 'Ext.
signal' (ID 11084) is set to ON.
The read-out ' -- ' means that 'Ext. signal' is set to OFF.
A230.4
A value for the desired flow temperature is indicated only when 'Input
type' (ID 11327) is set to ON.
The read-out ' -- ' means that 'Input type' is set to OFF.
