Rinnai N Series Multiple EZ Connection Cable – 3 Metres (AWEZC(N)-02) The Rinnai N Series Multiple EZ Connection Cable links two Rinnai N Series continuous flow water heaters into a single, sequenced system. Once connected, the two units communicate directly through their PCBs, monitoring water flow rate and alternating which unit leads, so the load is shared rather than falling on one heater alone. This kind of automatic sequencing reduces wear on any single appliance, improves overall system reliability, and keeps hot water delivery consistent across both units. For homes or light commercial premises with genuinely high hot water demand, it's a straightforward way to twin two heaters without adding an external controller. Note: this cable is not compatible with the Rinnai 16i. Key Features & Benefits
