So I'm working through trying to integrate a Stenner for chlorine injection into my pool equipment.
Currently I have a 240V 2 Wire single speed pump. I don't have nor can I practically get a 120V circuit to the pump location.
From what I gather this somewhat ties my hands with what I can do basically limiting my timer control options for the Stenner pump. I want to keep this as simple as possible.
From what it looks like I'll be stuck going with a 220V pump with adding something like a Intermatic 104 style timer for control instead of a simple outdoor cheap digital timer.
By using this style of timer my minimum pump run time is about 1Hr... So from my quick calculations of pump sizing if I go with the 3GPD my minimum daily dosage is .125Gal or with the 10GPD the minimum dosage is .41Gal.
Therefore with this timer arrangement and the 10GPD pump it's almost a half gallon a shot minimum. That doesn't sound like enough adjustability? But it also results in long run times if going with the 3GPD pump.
What are others doing with a 240 source circuit? I can't be the only one in this bind? Open to all and any suggestions. A variable output pump may be the answer but I was hoping to just get the fixed output again keeping it simple.
Side note I'm also looking to add some type of timer for my pump. The current setup is just a switch on the pump pad and the pump runs 24/7. I'd like to try and save some cost this summer by going to some shorter pump time. I was also thinking of using a simple 104 timer for that as well. And possibly doing daisy chained 104 timers like the 10404R config to handle the pump and stenner. But that all said since I have NO timer currently my options may be open to something more integrated like the 1353 for example but even that doesn't seem to do what I'd need by itself as it only will switch both legs of a 240 service using 2 of the outputs.
