My heater will not increase temps although everything appears to be working as normal. Upon selecting pool heat I get double green indicator lights but when selecting spa heating I get left led Green and right led red.In Miami water temps are appx 86 at current so I normally set spa to 100. I had it on for at least an hour and no movement at all. There are no errors on the display panel. I could not find a troubleshooting chart that spoke specifically to the variation between pool and spa leds but I assume possible there is something not registering correctly. Any help would be greatly appreciated.
