Rinnai Australia 6 Operation Manual
SMARTSTART® PRE-HEAT OPERATION
ABOUT THE SMARTSTART® PRE-HEAT SYSTEM
Preheat Function
The “preheat” function works in conjunction with various Rinnai water heater models and the
separately installed and optional Rinnai “Smartstart®” module.
When the “preheat” function is activated and used in accordance with these instructions, water in the
pipework connected between the water heater and the hot water outlets in your house is warmed
before any outlets are opened. This results in water savings and added convenience.
The preheat function is activated as follows:
1. Ensure that the hot water unit is on (temperature digits are displayed in the digital monitor ).
If more than one controller is fitted press the ‘Transfer’ button to pass on priority to your
desired controller. The ‘Transfer’ indicator will illuminate to confirm that priority has been
assigned to this controller and that the hot water unit is ready to deliver hot water.
2. Select the desired temperature using the 'Temperature' buttons until the required
temperature is displayed in the digital monitor .
3. Press the ‘Preheat’ button once. The ‘preheat’ indicator and the ‘In Use’ indicator will
illuminate, signifying that the preheat system has been activated.
4. Wait approximately two minutes before opening an outlet. This will allow the water in the
pipework to be warmed.
Other Water Controller Functions
Water controller functions such as temperature control and transfer of priority between multiple
controllers are not affected by the operation of the preheat. Such functions are described in the
applicable sections of this manual.
The waiting time may be longer or shorter than two minutes depending on your
particular installation configuration.
The preheat function is cancelled 5 minutes after activation and the ‘preheat’
indicator will go out. This is to conserve energy. To reactivate, simply repeat
steps 2-4 above.
* If the ‘preheat’ button is pressed and the ‘Smartstart®’ preheat unit is not
installed, the ‘preheat’ indicator will still light but there will be no preheat function.
The ‘preheat’ indicator will go out after a short time and will not affect the other
functions of the water controller or water heater.
