Rain Bird SST with Hydrotek 4000: Need Pump Relay & Delay

SST can't start pump directly — needs pump start relay. But Hydrotek 4000 indexing valve requires pump off-time between zones. SST lacks zone delay feature.

Options

Replace indexing valve with 4 electric valves ($20 each), wire to SST + pump relay.
Use Rain Bird ESP Modular — has start times, zone delay, pump start support.
