I installed a new Sta-Rite heater before opening my pool 3 days ago. The heater was purchased in the fall but remained in the factory packaging for the winter. I did the installation myself because my pool guy wanted $600 for a 30 minute job. Upon start up I have a HLS ERR on the display, I do not hear anything happen when i try to turn the heater on. Does anyone have any advice? My pool guy has never seen this issue, starting to think he is just trying to stick it to me for not paying him for installation.
