FYI - reply to my question to Hunter
Thank you for contacting Hunter Technical Service.
The SRC+ is not capable of operating 2 valves at the same time. The Hunter XC, Pro-C and ICC controllers do have the power to operate 2 valves wired together at 1 station terminal. Click on the link below for more information on these controllers.
