Last night I powered up the brain and reprogrammed it to use the 3.5 second pulse and then attached the H1/5 and the H1/8 wires (using the chart in the first post) to the actuator. But that did not work.

I tested the actuator and it does function.

Next step, rewire everything to the relays and try that again now that it is programmed to use the 3.5 second pulse.
