Temperature control 0 – 10 V input
If you have selected "Temp. contr" for the 0 –
10 V input, you can adapt the start
and stop point, if required, for the external 0 –
10 V input.
You can set the following:
–
The set value in °C for 0 V ("Temp. contr 0V equates to temp. control").
–
The set value in °C for 10 V ("Temp. contr 10V equates to").
The following linear curve is calculated from these values:
The start value (start point) of the curve is set to 0.6 V for a positive curve;
Fig. 16 shows the factory setting.
Call up the service level. "Gen. parameters" is shown as the first main menu.
Press "Display" to call up a submenu (here: "Min outside temp").
The display shows the selected submenu.
Turn the rotary selector until submenu "Temp. contr 0V equates to" or
"Temp. contr 10V equates to" appears.
Hold down "Display" and turn the rotary selector until the required set
value appears (here: "5°C").
The display shows the set value.
Release "Display" to save your input.
