The Rinnai Bathroom Deluxe Controller  works in conjunction with the Rinnai Kitchen Deluxe Controller.

Digital controllers allow you to select the exact temperature of the hot water at the tap within the controller temperature range. This has a number of benefits:

  • Safety: If you have young children, the hot water can be pre-set to a child-safe level for the period while you are filling the bath—a safety interlock feature prevents the water temperature from being adjusted from another controller while the bathroom controller is operating and hot water is flowing.
  • Ability to transfer control back to the kitchen controller at the press of a button.
  • No need to mix hot and cold water, this reduces the effect of temperature spiking when another tap in the building is turned on
  • You use your Rinnai INFINITY continuous flow gas hot water unit more efficiently as less gas is required to heat water to 40 °C (typical shower temperature) than at 55 °C (default temperature without controllers)
  • Allows diagnosis of problems (such as gas supply disruption) when the appliance is serviced by displaying 'error' codes, which the service person can utilise.

Rinnai's Bath Fill Controller that allows for adjustable bath fill settings and is compatible with all Rinnai tankless water heaters.

With extra features such as a clock, intercom, bath fill mode, and volume control. From basic temperature control to system troubleshooting to an automatic bath-fill function, Rinnai's remote controllers will give you maximum performance and enjoyment from your tankless water heater system.

The bath fill function allows a preset amount of water at a selected temperature to be run into the bathtub automatically. No special valve or accessory is needed to use this function aside from the BC-100V-1 controller. A few seconds after bath fill is selected a voice prompt will say "The hot water system is ready. Open the hot water tap." Once the preset amount of water has been reached the water heater will automatically shut off the flow of water until the bath fill mode button has been pressed again to turn it off.
