We have a new gunite pool and inground spa with all Pentair equipment, including lights, gas heater, pump, and easy touch control system. Any time that we use the heated spa (spa mode) and turn on the pool lights, the entire system will shut down in 10 to 30 minutes... the lights turn off, the heater turns off, and the pump turns off. I can turn it back on, however, it will shut down again in 10 to 30 minutes. This never seems to happen when in pool mode, or if using the spa without lights. The PB seems mystified. Has anyone else had a similar experience? Any suggestions are appreciated.
