High Voltage (120/240V) Pool Equipment All ECOMMAND 4 relays are double pole (they make/break both "legs" of 240V circuits) and are rated at 3HP/30A at 240V (1½HP/30A at 120V). Refer to the diagram below for typical relay wir- ing. 240 VAC Load 120 VAC Load 120 VAC Load Wiring relays for 240 VAC Pool Equipment Wiring relays for 120 VAC Pool Equipment Wiring GFCB for 120 VAC Pool Equipment WARNING: Do not use the ECOMMAND 4 to control an automatic pool cover. Swimmers may become entrapped underneath the cover. Two speed filter pump Requires 2 relays (FILTER plus one of the AUX relays) for proper operation of both speeds. IMPORTANT: Be sure to follow the wiring diagram below AND to configure the control logic according to the instructions on page 18. Lo Speed Hi Speed Common Ground 2-Speed Filter Pump N L2 L1 G Lights A ground fault circuit breaker must be used to supply power for high voltage pool/spa lighting. Low voltage lights will require an external transformer. For lighting systems that have both a light source and color wheel, connect the light source to the "Lights" relay and then connect the color wheel to one of the AUX outputs. 8 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
