I have a zoned, heat-pump system with two zones. The thermostats are
both pretty basic and don't indicate if/when the backup heat strips
are on, which is something I'd like to know. Does the zone controller
indicate when the strips are on? I assume there's a signal there I
could tap to get some indication.


Pretty sure you could simply connect a led between the "C" and "Wxxx" wires
at the air handler.

Or at the stat(s) ( provided the "C" wire has been run to them )

Others might chime in....
