Service The main unit keypad has a SERVICE key. This button 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, and the remote display/keypads are disabled (except for manual turn off for emergencies). 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. See Troubleshooting/Diagnostic Information (page 26) for more information about the service modes. Automatic System Operation The ECOMMAND 4 controls most of your pool equipment automatically in order to minimize the time spent working on your pool. Most of the pool equipment can be programmed to operate on a timeclock basis. In addition, the desired pool and spa temperatures can be programmed. This section will guide you on how to program the automatic operation for each function. The programming of automatic functions can be performed at either the main display/keypad located at the pool equipment pad or the in-home remote display/keypad. Using the programming buttons There are 5 buttons on each keypad that are used for programming (refer to diagram).
