Hayward E-Command 4 Model: ALL MODELS Operation - Page 27

Troubleshooting and Diagnostic Information The ECOMMAND 4 provides 2 different tools to aid in troubleshooting any problems that may occur in your pool and/or spa system. The Service mode will allow you to disable automatic operation and manually control most of the equipment (the heater and general purpose Valve3 output are the exceptions). The Diagnostic 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, their function is fully explained below. . Service Mode The 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 put the system into Service or Service-Timed mode by pressing the "Service" button. Pressing the "SERVICE" button once will switch the system into service mode which means that all automatic functions are disabled, 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 until manually taken out of service mode. Pressing the "SERVICE" button again will cause the ECOMMAND 4 to switch to service-timed mode which is very similar to service mode, except that the ECOMMAND 4 will automatically return to normal operation after 3 hours. During service timed operation, the "SERVICE" LED will flash and the time remaining 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 Indicator The "CHECK SYSTEM" LED will alert you when the ECOMMAND 4 detects any of the following conditions that are abnormal and require attention for optimal operation of your pool. Press "" to view all of the existing "Check System" conditions. • Water Sensor -- If the water sensor is either an open or short circuit. • Air sensor -- If the freeze protection feature is enabled (Configuration Menu/ Filter Config.) and the air sensor is either an open or short circuit. • Solar Sensor -- If the solar sensor is either an open or short circuit. • External Chlorinator Comm Error -- If the external chlorinator is enabled and the Aqua Rite or Swimpure is not responding. • Pool Bridge Comm -- If variable speed is selected for the Pool Filter and the VSC interface is not responding. • Pool VSC Comm -- If variable speed is selected for the Pool Filter and the Hayward VSC is not responding. • Pool VSC Err: x -- If variable speed is selected for the Pool Filter and the Hayward VSC is indicating and error. x is the same decimal error displayed by the VSC itself. For helpful troubleshooting information on any of these issues, go to the Diagnostic Menu and then scroll through the various items until you see the cause for the "CHECK SYSTEM" LED being illuminated. 24
