5.2 External Temperature
Set Fixed External Temperature
If you do not use an external temperature sen-
sor, you have the possibility to enter a fixed
external temperature. Set the parameter so that
External Temp shows on one data line (see
section 4.2). If no temperature sensor is in-
stalled, the data line will not show any reading.
Touch the External Temp data line on the
screen. A window (see picture below) will ap-
pear where you can enter the desired tempera-
ture.
Enter the desired temperature in degrees C
(21 °C in this example) and activate the Use
Fixed Ext Temp option by touching the button.
When the indicator square turns green, the
fixed external temperature is active.
The External Temp data line (and the graph, if
shown) will now say
“(fixed)”. As shown in the
image on the right, the external temperature will
immediately change to the temperature that
was entered, and will remain there until it is
changed again.
If you want to start using an external tempera-
ture probe, go to the Fixed External Tempera-
ture window and press the Use Fixed Ext
Temp to disable the fixed external temperature
function. The green square will turn grey.
