The following solution would however also be possible:

11.2.2 Parts list for solution 2:

Per room:

1 x 3-fold switch/dimming actuator with integrated brightness controller
0.25 x 8-fold shutter actuator (used for 4 rooms)
1 valve drive with 2 integrated contact inputs
1 heating controller with integrated 2-fold push-button
1 x 4-fold push-button
1 display with at least 8 display and operating functions
___________________________________________________________________
Total per room 5.25 devices x 8 = 42!
In addition:
1 logic module for the conversion of analogue threshold values into binary signals
(shutter)
1 logic module for all binary connections for the group signals
1 weather control unit (as above)
1 information panel (as above)
1 time master (because the time clock functions can also be detected by the analogue
threshold value generator, when it receives the time on a regular basis).
___________________________________________________________________
This totals only 47 bus devices! Only 1 line remains, instead of 3 as in the first
case!

Conclusion: Through an accurate survey to determine which optimum device
configuration is possible, you can save up to 50% of the costs!
