Just got an easytouch installed today. Still trying to fully understand it and I am a bit confused. Mostly around Spa mode vs Pool mode. It appears in pool mode even if the pool is up to temp, the pump still runs, but in spa mode, once set temp is reached, the heater goes off as expected, but shortly there after the pump stops as well. Once temp drops to a degree below set, the pump comes on and the heater fires up. Is this normal?
