Every thing was working great with the Polaris. I changed to pool temperature to match the current reading, and now the auto-cycle and sanitizing lights will not come on, and the display is blank. I tried pressing the restart and test buttons simultaneously to reset, and nothing changed. The sanitizing light comes on if I press the 24 hour boost. I completely disconnected the electrical supply to the system and left it for 30 minutes, then hooked it back up. Still no reading on the display, and auto-cycle and sanitizing lights are still off. I tried resetting the water temp, and run time
