Pool Filter

Troubleshooting and Diagnostic InformationThe ECOMMAND 4 provides 2 different tools to aid in troubleshooting any problems that may occur inyour pool and/or spa system. The Service mode will allow you to disable automatic operation and manu-ally control most of the equipment (the heater and general purpose Valve3 output are the exceptions). TheDiagnostic Menu will provide some detailed information regarding system operation.While both of the features are primarily intended for the use of the professional service technician, theirfunction is fully explained below. .Service ModeThe main unit keypad has a SERVICE button that is used primarily during servicing of the pool equipment.If you want to completely disable the automatic operation and operate the system manually, you can putthe system into Service or Service-Timed mode by pressing the "Service" button. Pressing the "SER-VICE" button once will switch the system into service mode which means that all automatic functions aredisabled, the optional remote display/keypads are disabled (except for manual turn off for emergencies).The outputs can be manually controlled by pressing the buttons on the local display/keypad. The red"SERVICE" LED will be illuminated and the ECOMMAND 4 will remain in this mode of operation untilmanually taken out of service mode.Pressing the "SERVICE" button again will cause the ECOMMAND 4 to switch to service-timed modewhich is very similar to service mode, except that the ECOMMAND 4 will automatically return to normaloperation after 3 hours. During service timed operation, the "SERVICE" LED will flash and the timeremaining will be displayed on the remote display/keypad(s).Pressing the "SERVICE" button again, will return the ECOMMAND 4 to normal (automatic) operation.Check System IndicatorThe "CHECK SYSTEM" LED will alert you when the ECOMMAND 4 detects any of the followingconditions that are abnormal and require attention for optimal operation of your pool.
