BUTTONS AND INFORMATION ON THE DISPLAY
The following information is displayed directly on the touch screen:
- Current room temperature for the relevant heating circuit
- Heating circuit name
- Information on proper communication
- Time program for the relevant heating circuit - current day (ongoing)
The orange segments show the desired operation set to COMFORT temperature , the white
ones to SET BACK temperature
- Button to switch between heating circuits
Using the arrows , it is possible to briefly display (10 s) the room temperature (time program)
read by other room units connected (paired) to the ACD03/04 controller. It is also possible to
display the domestic hot water temperature (if read).
- Relative air humidit
Relative humidity is only measured at room temperatures higher than 0 °C.
- Current outdoor temperature
- Minimum / maximum outdoor temperature in 24 hours
