As I understood previously, PAC is pretty flexible, but not easy to configurate unit. Interesting if it could: 1. Monitor General Input Module measured values and... - send group addresses in C-Bus (to change pictures on Mono C-Touch with temperature digits) - control temperature using heating and cooling group addresses - have a user-changable variable to change desired temperature to control (temperature used as an example, it could be CO or air pressure or any other) 2. Control using RS232 commands... - boilers, HVAC - AV systems 3. And issue group addresses in C-Bus depending on incoming RS232 messages, use in in Logic (as axample: to issue different commands into HVAC system, depending on it's RS232 reported state) If anyone has examples of doing so, please post. No AMX/Crestron needed anymore, if this is possible? =)
