The QOLSYS INC IQWV908 is a Z-Wave Plus smart water valve controller designed for automated shut-off and remote control of residential or light commercial water supply lines. It integrates with Z-Wave Plus compatible smart home and security systems, allowing installers to add water management capabilities to an existing automation network. The IQWV908 is sold as a single unit and is typically installed by licensed plumbers or security system technicians working with integrated smart home platforms.
The IQWV908 is suited for residential applications where remote or automated water shut-off is required, such as leak detection response, scheduled shut-off routines, or system-level water management. It pairs with Z-Wave Plus hubs and controllers, making it a practical addition to smart home security and automation installations where water damage mitigation is a priority.
Designed for use with Z-Wave Plus compatible smart home hubs and security system controllers. Refer to your hub manufacturer documentation to confirm Z-Wave Plus device pairing support before installation.
Installation should be performed by a licensed plumber or qualified security system technician familiar with both plumbing shut-off valve installation and Z-Wave device pairing procedures. Shut off the main water supply and depressurize the line before beginning any plumbing work. Follow all applicable local plumbing codes, including IPC guidelines, when making pipe connections. Complete the plumbing installation before pairing the device to a Z-Wave Plus hub per the controller manufacturer instructions.
