I am undergoing a major renovation and have just had a Hayward Tristar VS 900 pool pump installed. I also just ordered a Stenner 45mhp10 pump for chlorine/bleach injection. What's the best way to set this up so that the Stenner only runs when the pool pump is running? Can the Tristar timer start and stop the Stenner pump?

Tom,
I took a quick look at the manual and did not see anything that made it look like the pump could tell any external device that it was running.
You can control the pump remotely with relay input and even stop the pump with an external input, but I saw nothing about the pump having an external output.
Let's see if some of the other member have a different idea.
Thanks for posting,

With all those internal timers, you'd think they thought of that...controlling an external device that might be dependent upon the status of the pump.
Tom,
I find it hard to believe also...
It seems that someone here built, or was going to build, a current sensing device that could be connected to the pumps AC input line. When it sensed current flow in the power line it would close a relay to indicate the pump was running.
If you want you can try the search box in the upper right of your screen and see if you can find anything.

I posted this question thru Hayward's support interface. If their response pushes this discussion any further (one way or the other), I'll post here.
The current sensing relay that's gotten the most press around here is the Macromatic. There are others of course and they all work about the same way.
Adding a current sensing relay on the power input to the pump would work. You'll have to be able to set the low current sense just above the parasitic drain of the electronics when the pump isn't running.
