2) The circuit is abnormal.
Step 1 Check whether the skylight ceiling controller works properly.
Connect the skylight ceiling controller to 220 V AC power and use a multimeter to check whether power is supplied to components properly.
Y: If the voltage is normal, the skylight ceiling controller is functional. If components are faulty, replace the faulty ones and check whether the fault persists.
If the fault is rectified, troubleshooting is complete.
If the fault persists, go to Step 2.
N: If the voltage is abnormal, the skylight ceiling controller is faulty, and the fault persists. Go to Step 2.
Step 2 Check whether the components are properly connected to the skylight ceiling controller.
Check that components are reliably connected to the skylight ceiling controller. Use a multimeter to check the skylight ceiling controller for short circuits or disconnection section by section.
Y: If the circuit is faulty, replace the circuit and check whether the fault persists.
Y: If the fault is rectified, troubleshooting is complete.
N: If the fault persists, contact Huawei technical support.
N: If the circuit is normal but the fault persists, contact Huawei technical support.
