Hello, Good day.

Should it be possible to set up the management on VLAN20, or is it strictly required to use VLAN1 for management?
 

I made small home lab, where I tried it. 

devices:
- Omada Controller, OC200 v1.0, fw. 1.34.2
- Omada AP, EAP115 v 4.0, fw. 5.09
- Cisco switch, WS-C2960G


solution "A"  - management is on VLAN1
                       -  it is working well

solution "B"  - management on VLAN20 (requested solution)
                        - Omada Controller can't find the AP.
