Foos,
I'm not sure what the point of having a Spa fill line is when you have automation??? Taking what Matt says and putting it into my own words, here is how I thought the EasyTouch works...
Pool Mode.. Water is sucked from the Pool through the Intake valve, through the pump, filter, heater, SWCG, and then through the Return Valve and sent back to the Pool.
Spa Mode... Water is sucked from the SPA through the Intake valve, through the pump, filter, heater, SWCG, and then through the Return Valve and sent back to the Spa.
Spillover Mode... Water is sucked from the Pool through the Intake valve, through the pump, filter, heater, SWCG, and then through the Return Valve and sent back to the Spa.
So what is the point of the Spa fill line again???
