BlueSpray is designed to operate 24V AC irrigation solenoid. We have not tested it with any other valve, so we can't say that we support it.
That being said, I've read the Jandy brochure, but am not sure if it's 24V AC or DC. Our circuit can handle 4A RMS, but that is at the edge of its operating limit.
BlueSpray currently is programmed to operate in minutes. It can be done in seconds, but not supported in current firmware.
