Hayward E-Command 4 Model: ALL MODELS Operation - Page 6

Note that if the pump has been off for more than 30 seconds, it will run at high(est) speed for 3 minutes regardless of selection. This high speed operation helps allow the pump to prime and establish normal water flow. Freeze Protection: This function protects the pool, plumbing, and equipment against freeze damage. If Freeze Protection is enabled and the AIR temperature sensor falls below the preset freeze protection temperature (see Filter Configuration), the ECOMMAND 4 will turn on the filter pump to circulate the water. Lights, Aux1 and Aux2 Outputs Standard Relay: Manual operation of all 3 relays is identical. Assuming that the relay is currently off, simply press the appropriate button to turn on the relay. If the relay does not turn on, it probably is due to the "interlock" feature (which was set up in the Configuration Menu) being activated that requires the filter pump to be running and the valves to be in the pool-only position. This protects pumps and other equipment from possible damage. If the controlled output is on, pressing the appropriate button again will turn off the relay. Manual turn off is disabled if the "Freeze Protection" feature is enabled and the air temperature is less than the selected freeze temperature threshold. Dimmer Relay: If Lights or an Aux output is configured as a dimmer, pressing the corresponding button will generate a temporary display which shows the dimmer output level (Off - On 100%). Pushing the "+" or "-" button changes the level in increments of 20%. When the desired output level is displayed, press the corresponding button again to turn off the display and return to normal operation. When the Lights or Aux output comes on again (either manually or automatically), the dimmer output level will be the same as the last time that it was set. Pool/Spa Valves Pool-only or spa-only systems: The POOL/SPA button has no function. Pool and Spa systems without spa spillover: In pool-only mode, the left LED next to the POOL/SPA button is illuminated. Pressing the POOL/SPA button will switch the ECOMMAND 4 to spa-only operation (right LED illuminated). Pressing the POOL/SPA button again will switch back to pool-only. Note that the filter pump will turn off while the pool/spa valves are turning. Pool and Spa systems with spa spillover: In pool-only mode, the left LED next to the POOL/SPA button is illuminated. Pressing the POOL/SPA button will switch the ECOMMAND 4 to spa-only operation (right LED illuminated). Pressing the POOL/SPA button again will switch to spa spillover operation (both LED's illuminated). Pressing the POOL/SPA button again will switch back to pool-only. Note that the filter pump will turn off while the pool/spa valves are turning. 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 23) for more information about the service modes. 3
