8.2 Displays
• Room temperature:
If a room sensor or room unit is connected to the PPS interface (A6), the acquired
temperature will be displayed separately for each heating circuit
• Outside temperature:
The displayed temperature is delivered by the analog outside sensor (connected to
B9) or via data bus (refer to subsection 20.2.4 "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
temperature reset)
• D.h.w. temperature:
The temperature displayed is that measured 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 separately for each heating circuit is the temperature
measured with the relevant sensor.
If button
or is pressed, the controller will display the current setpoint
