The standard diagram explains how to safely and correctly use the ZEN78 High Power Relay to control any 240 V load, including pool equipment such as pool pumps, pool lights, heaters, and filtration systems. The ZEN78 is designed for high load applications commonly found in pool environments and allows reliable Z Wave control of equipment that traditionally operates from a dedicated 240 V circuit.

Before using this diagram, it is critical to confirm that the equipment you plan to control is in fact rated for 240 V operation. Due to the inherent safety risks associated with pool equipment and high voltage wiring, the installation should be performed by a licensed electrician who is familiar with local electrical and pool safety codes. A wall switch is not required for ZEN78 operation and is optional in most installations, however some local regulations may mandate a physical disconnect or manual control, so code compliance must always be verified before installation. This diagram is intended as a general wiring reference and does not replace professional electrical design, inspection, or local code requirements.
