Q. Why won't my Control Hub connect with my Wiring Centre?
A. If you have the 'Press U1' popup message on the Control Hub but when you press the U1 button on the Wiring Centre nothing happens, then there is a wiring issue between your Control Hub and your Wiring Centre
You shoud check:
- The connections on the back of the Control Hub (b+ and b-)
- The connections on the Wiring Centre C4 (b+ and b-)
- The connections on the External Temperature Sensor (if you have one)
