Thanks Sean;

Yes, the space heater has its own IR receiver. I have set up all communication from the MX-3000 to the MSC-400 as RF signals only - no IR. Also the IR emitters for the lighting are far away from the space heater. Nevertheless, I'll give it a shot and cover up spacer heater's receiver.

On the 'current/RF' idea, the heater is actually on another circuit. Nevertheless should that interference issue not be the other way around? In my case triggering the light macro causes the heater to turn on. But along those lines, I have only a few 'normal' lamps (maybe a total of 400 watts).

BTW, before I got the MSC-400 I was using a MRF-350 instead. The lighting macros resided in the 3000. I never experiences any such issues there.


All;
Please keep those ideas coming.....

Thanks!
