External signal for desired flow temperature<br />
A voltage (0 - 10 V) can be applied to the input terminal S10 in<br />
order to determine the desired flow temperature.<br />
The measured voltage on input S10 must be converted to a<br />
temperature value by the controller. When the voltage gets higher,<br />
the desired flow temperature increases.<br />
The following settings set up the scaling.<br />

The actual desired flow temperature is indicated by the unit °C.<br />
Read-out:<br />
- - : External voltage signal is not connected..<br />
°C : External voltage signal converted to desired flow<br />
temperature.<br />
Push the dial to see the graph and enter the value sets for the input<br />
voltage (1 and 10 volt) and displayed desired flow temperature.<br />
Desired flow temperature: 10 ... 120 °C<br />
Fixed voltage settings: 1 V and 10 V<br />
Factory settings: (1,10) and (10,100)<br />
This means that the ‘Desired flow temperature’ is 10 °C at 1.0 V<br />
and 100 °C at 10 V.<br />
Typically, the higher the voltage, the higher the displayed desired<br />
flow temperature.<br />
Example: Relationship between input voltage and displayed desired flow<br />
temperature<br />

This example shows that 1 volt corresponds to 10.0 °C and 10 volt<br />
correspond to 100 °C.<br />

The external voltage signal must be higher than 1.0 V in order to<br />
activate the override.<br />
