I think on a UM-1 you would need 2 pairs of I/O configured in double throw mode (dual throw port config) to use a CR05 valve natively. I would use CR03 valves with the SPST relays native on the UM-1, or use a SPST to trigger a supplemental board of DPDT relays to cycle your CR05 valves.
Edit: Looking at your last picture, can I assume you have a relay board of SPDT relays? If so, use 2 I/O from the UM-1 and configure the dual throw port config, wiring each I/O to one of the SPDT relays and wiring the relays as you have depicted.
