Any help would be appreciated. Pentair Ultratemp about 4 years old. The control panel lights up and display is normal, no error codes. But, the unit will not start when the on/off switch is depressed, and the on light is not illuminated.
I am thinking of installing a rather large, 20'X20' solar pool heating panel on my flat roof. I calculate the load to be about 4.3 pounds per square foot. Do you think the added weight will be a problem?
