Stand alone system
If the system is of the stand-alone type, the temperature set by
the user can be displayed only through two digits (bar-graph not
operating). It is also possible to choose not to display the
temperature.
If the user chooses to display it, the values that can be set are
between 15°C and 32°C (59 to 90°F).
Room temperature display
From the configuration menu, the user can also decide to display
the room temperature through the two digits on the display.
This temperature will always be displayed in the Off mode.
The temperature set by the user will no longer be displayed
through the 2 digits. This option is available both in the stand
alone and communicating system.
If the stand alone system is selected and the user wants the room
temperature to be displayed, no graphic value will be displayed
when the UP or DOWN keys are pressed for temperature
adjustment.
If the communicating system is selected, the temperature change
decided by the user is shown all the same by the bar-graph
segments colouring in black.
The figures below show some examples referring to a stand alone
system (Fig.A) and a communicating system (Fig. B): the UP key
should be pressed 3 times with a 22°C room temperature.
