Laszlo --> ok for the Air Con .
Basically need to add semi colon NOT commars between textes.
However, is it normal i must choose TRUE or FALSE ??
Idea is the IF rule should set this rule right ? Not for me to choose if true or false.
--> If you could expand on the other point concerning occupants and zones a bit more that would be appreciated. See my question above -- HOW TO ASSIGN NAMES LISTED TO ZONES ?
