I am new to these forums, and KNX
in general. I have a few interesting items which I hope someone can help me with.
I have 2-gang switches (rockers) - not sure if I can mention the manufacturer name here, so all I will say is the 2-gang version can be used to actuate up to 4 independent switches, via a 'toggle' function.
I also have 3-gang switches of the very same style - but I just found out that the application of the 3-gang version does not support toggle - so it only allows 3 independent switches to be used - kind of crazy, especially as they are more expensive!
So I have 2 things I wanted to ask:
1) How does 'toggle' work in practice with light groups -
say I have 2 lights: light A and light B
and 3 switches to control them: light A, light B, and light a&b together
The idea here would be that I could turn on indvidual parts of a hallway by some switches, or else the whole hallway together by another switch
The switches are setup to use the 'toggle' mode, so a single push button turns off and on the same light/group.
Does the toggle 'logic' reside in the switch
itself, or in the actuator?
What would happen if I turn on light A, and then press the switch
to turn on both A&B - will A go off and B on (i.e. the actuators individually toggle) ?
Do I need to send messages back from the actuator to the switches so they can know the status at all times?
Can anyone give me an example of how this should be done?
2) As I have the 3-gang switches without the toggle, is there a way I can 'make' the toggle function by using logic. I have a touch
-screen with built-in logic - and I was thinking I could do:
say the top-button pair has 'on' and 'off' for group address '1' - but I want to convert this so pressing 'on' will instead toggle group address '2' and pressing 'off' will toggle group address '3' - could the logic be setup so:
logic received 'on' and 'off' on group address '1' - if it received 'on', it will send a 'toggle' command to address '2' and if it received 'off', it will send a 'toggle' command to address '3'.
Of course, in order for it to know how to toggle, it would have to remember the state - is this possible with logic?
I know these questions are very detailed. I would really appreciate any and all help - I have searched the web and this form as much as I can, and was not able to find any detail to explain this.
Thanks in advance!
