Note that P4 models can control one Variable Speed Pump (VSP) using the Filter Output only. Disregard references to VSPs on the Lights and Aux Outputs. Hayward Variable Speed Pump Proper installation of a Hayward Variable Speed Pump (VSP) includes high voltage input wiring, low voltage communication wiring, and menu configuration/settings. This Pool Control can operate one VSP. Refer to the adjacent diagram for proper input wiring to the VSP. Wiring from the 220V breaker must NOT connect through the Filter relay. 220 VAC input power to VSP Low Voltage Wiring Valve Actuators The ECOMMAND 4 can control up to three automatic valve actuators. Two of the valve outputs are dedicated to the pool/spa suction (Valve2) and return (Valve1) valves. Valve3 is for general purpose use (solar, water feature, in-floor cleaner, etc.). For installations with solar heating, Hayward offers the AQ-SOL-KIT-xx solar kit that contains a valve, actuator, and extra temperature sensor. The "xx" indicates the valve type from the choices below: -1P 1.5" Positive Seal -2P 2" Positive Seal The ECOMMAND 4 is compatible with standard valve actuators manufactured by Hayward, Pentair/ Compool, and Jandy. See diagram on page 6 for the location of valve connectors. Heater Control The ECOMMAND 4 provides a set of low voltage dry contacts that can be connected to most gas heaters or heat pumps with 24V control circuits. Refer to the diagram on the following page for a generic connection. The manuals supplied with most heaters also include specific wiring instructions for connecting the heater to an external control (usually identified as "2-wire" remote control). For millivolt or line voltage heaters, contact Hayward Tech support at 908-355-7995. Refer to the diagrams and the information on the following pages for more details on the connection to several popular heaters. 9 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
