Troubleshooting/Fault Codes Code/Fault Indications The freeze protection in the EcoStar does not work properly. The freeze protection is actually for protection of the EcoStar drive. It will not and should not be expected to protect any plumbing or other equipment from freezing temperatures. (page 23) My EcoStar is connected and operating via the GL/Hayward control. The Speed buttons and Quick Clean buttons on the pump interface do not work. This is correct. When the control is operating the EcoStar, the Speed buttons and the Quick Clean button is inactive. Only the Stop/Resume and Menu button is active. The EcoStar is experiencing interference with an X-10 home automation control and is causing other devices to come on and off. Try changing channel on X-10. If problem persists, purchase (2) model XPF 20A 3-wire noise filters through X-10 website. The EcoStar is wired and set to operate via the GL/Hayward control. When a command is sent to the pump, the EcoStar interface reads "Remote Stop Engaged". This indicates that the comm. wires from the control are connected in the EcoStar to the input terminals for relay control. Remove wires and connect to the comm. bus plug on the drive (page 10).
