Nik,
I have been thinking about your chiller issue and have an option that might work for you..
Just some quick background so that we are all on the same page. The SWCG will only work if the Pump/Filter relay is closed. This relay will only close if the system is in either the Pool mode or Spa mode. Normally, to run 24/7, you would set the Pool Circuit to be on 24/7, which would close the Pump/Filter relay 24/7. By system design, this means that the pump can
never run slower than the speed set for the Pool Circuit.
The pump knows what speed to run based on which Circuit, or Circuits, are "On". To make the pump run faster, you have to use Feature Circuits and assign speeds to them. If you look at the screenshot below, you can see where my Pool Circuit is assigned a speed of 1250 RPM. I also have three Feature Circuits... Skim Low which runs the pump at 1500, Skim High which runs the pump at 2000, and Waterfall which runs the pump at 2800. I can make the pump run faster or slower by turning these Feature Circuit on or off. But, I can never make the pump run below 1250 because the Pool Circuit is scheduled to be on 24/7.
One option would be to set up your Pool Circuit for say 500 RPM (as an example). Schedule the Pool to be on for 24/7. Then set up a Feature Circuit and name it "Pool Fast" (You can name it anything you want..) Schedule Pool Fast to run 24/7 at say 1500 (or whatever speed you are running now). Since both circuits are scheduled to run 24/7 then the pump will never run at 500 RPM unless you shut off Pool Fast. You can do that manually or with a schedule.
Again, not sure that is what you want to do, but it seems that what you want to do can be done a couple different ways. Tell me how you wish your system to work and I'll see if I can come up with an option that will work for you.
Thanks,
Jim R.
