So here we are almost 6 years since the first post in this thread and still no option for the master pump on for specific zones.
Let me ask for some help from this crew as it looks like I am going to have to go the relay switch route this year. I need help understanding how to wire what I am looking to do so let me summarize.
I have an injector pump that injects rid o’ rust into the sprinkler system. Currently this works on the Rachio by setting the injector pump to turn on via the master pump valve connection. However, this makes the injector pump turn on and use rid o’ rust for EVERY zone I have any time I turn the sprinklers on. Rid o’ rust is not cheap and I only want the injector pump to send rid o’ rust to a few zones that spray over walkways and fences - not all my zones.
For example…I would like to have the injector pump with rid o’ rust turn on and be in use for zones 1, 2, 3, 4, 9, 11 and off for all the rest.
Could someone on here walk me through the exact solutions I need to buy and wiring so that the injector pump only turns on for the zones I need it for and is off for zones I do not need it for?
P.S. Unless @franz has it working in software about to be released…
