Is it normal for the units to have a slight warmness to the touch on the top rear of the unit. They are plugged in but not on. Been gone for a day and came and feel that they are warm to the touch as if they have been recently shut off.

That is normal. Even when "off" (it's actually "standby") the processor is still active, which is how it can be turned on remotely.
