Mobile Interface
iZone Home
Overview
The iZone Home mobile application provides a unified platform for monitoring and controlling iZone climate control systems via a mobile device. The app connects to the system through the Smart Hub (COCBH) over a local Wi‑Fi network or remote 5G network, enabling real-time control of unit operation, zone management and temperature setpoints.
Users can select between multiple user interface modes within the app:
- Nova interface: This is the default user interface. It is actively developed and deployed across all modern iZone systems, providing full feature support, multi-system control and an updated user experience. Read more...
- Nexus interface: Represents a legacy UI option retained for compatibility and user preference. While still functional, it is approaching end-of-life and no further development or feature updates are being implemented. Read more...
- Navi interface: Upcoming simplified UI designed for single-system control. It is intended to provide a streamlined user experience with reduced complexity, primarily for basic residential applications. Coming soon...
