Displays

• Room temperature:
If a room temperature sensor or room unit is connected to the PPS interface (A6), the
temperature acquired will be displayed
• Outside temperature:
The displayed temperature is delivered by the analog outside sensor (connected to B9)
or via data bus (refer to subsection 21.2.4 "Outside temperature source").
If buttons and are pressed for 3 seconds, the displayed outside temperature will
be adopted as the composite and the attenuated outside temperature (outside tem-
perature reset)
• D.h.w. temperature:
The temperature displayed is that acquired with the d.h.w. sensor. Depending on the
plant configuration, this can be d.h.w. flow sensor B3 (plant types x–4) or storage tank
sensor B31 (other plant types with the exception of x–0).
If button or is pressed, the controller will display the current setpoint
• Flow temperature heating circuit:
The temperature displayed is that measured with sensor B1.
Exceptions:
Plant types 3–x and 7–2:
−
The temperature displayed is that measured with sensor B12
Plant types 0–x:
−
No display
If button or is pressed, the controller will display the current setpoint
