|Honeywell R8239 "Fan Center"|
|Signal comes in the bottom and goes out the top to the fan center in the cable on the left.|
But rather than straighten out the world, I just mindlessly wired the new unit exactly like the old one.
Except I did not like the short wires between the bus shown in the bottom photo to the fan center. while it looks tidy it means that fat, old, nearsighted men have to squat on the ground and do all the wiring inside the device. It is SO much nicer when you can detach the device and hold it in your lap as you switch it over, one wire at a time.
