ALWAYS......
Test the temperature of the water with your elbow before placing your child in the bath, also carefully feel water before bathing or showering yourself.
Supervise children whenever they are in the bathroom.
Make sure that the hot water tap is turned off tightly.
CONSIDER.....
Installing child proof tap covers or child resistant taps (both approaches will prevent a small hand being able to turn on the tap).
Setting your appliance at a maximum temperature of 50°C (Contact Rinnai Australia).
NEVER…..
Leave a toddler in the care of another child. They may not understand the need to have the water temperature set at a safe level.
Rinnai Australia 4 Operation Manual
FEATURES AND BENEFITS
Congratulations on purchasing the latest technology temperature controlled Rinnai continuous flow water heating system.
• The Rinnai Continuous Flow water heater products NEVER RUN OUT of hot water. Whilst
electricity, water and gas supplies are connected, hot water is available whenever hot water taps are open.
• Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEMPERATURE of the
hot water supplied. The water temperature may be limited to various values. This is particularly useful when the hot water unit is installed where young children or the infirm may be using the hot water.
• The Rinnai Continuous Flow water heater products are Fan-Assisted (power flued) appliances. This
makes them COMPACT, saving both floor and wall space.
• The temperature of hot water is CONSTANTLY MONITORED by a BUILT-IN SENSOR. If the
temperature of the hot water rises to more than 3°C above the selected temperature the burner is turned OFF and only turned ON again when the temperature falls below the selected temperature.
• The burner lights automatically when the hot water tap is opened, and goes out when the tap is
closed. IGNITION IS ELECTRONIC, so there is no pilot light. When the hot water tap is off, no gas is used.
• This Rinnai Continuous Flow water heater product is supplied with one “MC-503” wireless water
controller that is pre-programmed as a master controller.
• Additional ‘MC-503’ wireless water controllers are available as an optional extra.
• 'Deluxe' or 'Universal' Water Controllers are also available as an optional extra. Depending on the
models chosen, these offer the following features:
• Bath fill function (Deluxe Bathroom Control Only).
• Voice Prompting (Deluxe Control Only).
• Clock (Deluxe Control Only).
• Up to four water controllers can be fitted. See page 10 for details.
• The "Smartstart®" system when fitted can pre-heat the water in the pipe-work between the water
heater and the hot water outlets. This results in water savings and reduces waiting time for heated water at the outlets.
• Operating NOISE LEVEL IS VERY LOW.
• ERROR MESSAGES ARE DISPLAYED on the Water Controllers and Status Monitor*, assisting with
service. *All models in the range covered by this manual have a “Status Monitor”.

To clean your water controller(s) use a soft damp cloth with a mild detergent.
Do Not use solvents!
Depending on the weather conditions and the length of the pipe between the hot water unit and the outlet in use, there may be a variation between the temperatures displayed at the water controller(s) and the temperature of the water at the outlet.
Whilst hot water outlets are open the set temperature may be lowered. However they cannot then be raised above 43°C. In addition transfer of 'priority' between controllers is not possible. These are safety features.
There is no need to turn the water controller(s) off after use. However, if you prefer to turn the water controller(s) off, selected temperatures to a maximum of 50°C will be stored in the system memory at all times whilst mains power remains connected.
As a safety precaution, if a Kitchen Controller's temperature is set above 50°C, transferring and then returning 'priority' to the Kitchen Controller will result in a default set temperature of 50°C being selected. This is a safety feature.
Do Not push the On/Off button on any Controller when the ‘Red’ water heater ‘In Use’ indicator is illuminated as this will turn off the water heater causing the water to go cold. Someone maybe in the middle of having a shower or filling a bath.

Rinnai Australia 8 Operation Manual
GENERAL WATER CONTROL INFORMATION
NOTE NOTE
RADIO COMMUNICATIONS
Rinnai wireless water controllers are classified as short range radio communications devices and referred to as Low Interference Potential Devices (LIPD’s) in AS/NZS 4268*. As such, they operate in the same radio frequency spectrum as many other devices classified as LIPD’s such as garage door openers and keyless automobile entry systems. Although interference with other LIPD's is unlikely, it is not guaranteed interference will not occur.
Rinnai wireless water controllers must not be used in the vicinity of other devices if radio interference with such devices could result in a dangerous situation, unless it is verified that interference will not occur. Possible examples are medical devices and fire alarms.
*AS/NZS 4268 ‘Radio Equipment and systems – short range devices – Limits and methods of measurement’.
WATER RESISTANCE
The MC-503RC Wireless water controller is a water resistant device, however excessive exposure to water such as immersion may result in damage to the controller.
• DO NOT immerse the controller into water.
• AVOID direct exposure to water or steam as these conditions may cause a malfunction.
• ALWAYS AVOID exposure to water when the battery compartment is open.
• When cleaning your water controller use ONLY a damp cloth and a mild detergent.
MAXIMUM DELIVERY TEMPERATURES
Rinnai continuous flow water heaters are factory pre-set to various maximum delivery temperatures depending on model and their intended application. For the majority of applications, the factory pre­set temperature is appropriate. In the unlikely event this is not the case this setting can be increased or decreased by an authorised person such as a licensed plumber.
This does not apply to “50 degree compliant” models. To meet the regulatory requirements the maximum delivery temperature is factory set and sealed.
Factory pre-set delivery temperatures for the various models are as follows:
MODEL NUMBER MODEL NAME FACTORY “PRE-SET”
MAXIMUM DELIVERY
TEMPERATURE (°C)
REU- VRM2626WD INFINITY 26 Touch 60 Yes
REU- VRM2626WD-50

Water controllers allow precise temperature control by the user. When used correctly, the hot water unit will deliver the selected temperature, even when the water flow is varied, or more than one tap is in use. Each water controller can be individually programmed, however the water heater can only deliver one set temperature at any time. The available temperatures (°C) are as follows:
Master Controller (used in kitchen):
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C* 60°C*, 65°C*, 75°C*
Bathroom Controller (used in bathrooms, ensuites, toilets and laundry):
Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Whilst hot water outlets are open the set temperature may be lowered. However the set temperature cannot then be raised above 43°C. In addition transfer of 'priority' between controllers is not possible. These are safety features.
Rinnai Australia 9 Operation Manual
GENERAL WATER CONTROL INFORMATION
Suggested temperatures are:
Kitchen 50°C ~ 55°C*, Shower 37°C ~ 43°C
* Temperature may not be available on all installations. Rinnai water heaters can be programmed to deliver higher temperatures via the kitchen controller. Contact Rinnai for more details.
These temperatures are suggestions only. You may find higher or lower temperatures more comfortable. Maintaining lower temperatures helps save energy. To obtain water temperatures lower than 37°C simply add cold water.
The temperature of outgoing hot water is constantly monitored by a built-in sensor. If the temperature of the outgoing hot water rises to more than 3°C above the selected temperature shown on the digital monitor, the burner will automatically go out. The ‘In Use’ indicator will also go out. The burner will ignite again once the outgoing hot water temperature falls to that shown on the digital monitor.
Wireless water controllers can be fitted along with wired 'Universal' and 'Deluxe' water controllers. Wireless and Universal water controllers allow temperature selection only. Deluxe water controllers allow temperature selection, have a clock function and on the Deluxe Bathroom water controller BC­100V a shower saver / bath fill function is also available.

When the water heater is in the ‘Off’ condition only the communications and battery status indicators are displayed on the digital monitor. To turn the water heater ‘On’, press the On/Off button once (if Child lock
is activated see page 12). The communications indicator will briefly illuminate to confirm that a signal has been sent to the transceiver connected to the water heater.
The transfer indicator and the water temperature display will flash until communication between the controller and transceiver is complete. When the display stops flashing the water heater is ready to supply hot water.
ADJUSTING TEMPERATURE
Simply press the 'hot water temp' or buttons until the required temperature is displayed on the digital monitor. The water temperature and any active status indicator will flash until communication between controller and transceiver is complete. DO NOT open the hot water tap until the flashing stops and the desired temperature is displayed.
To operate the water heater, open any hot water tap. This will automatically light the burner, providing hot water. The ‘In Use’ indicator
will illuminate on the water controller.
Once the hot water is running, if the set temperature is either too hot or cold press the or buttons until the desired temperature is reached.
Whilst hot water outlets are open the set temperature may be lowered to a minimum of 37°C. For safety, it cannot then be raised above 43°C until all hot water taps are closed.
If the water heater is turned ‘Off’ whilst hot water taps are open it can not be turned back ‘On’ until all hot water taps have been closed.
Always check water temperature at the outlet before use.
A parent or carer should always check the temperature
Rinnai Australia 11 Operation Manual
before a child is placed in contact with hot water, see page 4.
WIRELESS WATER CONTROLLERS
NOTE
3 seconds
NOTE
TRANSFERRING PRIORITY BETWEEN WATER CONTROLLERS
To control the water delivery temperatures when using two or more controllers it is necessary to have priority transferred to the water controller you wish to use.
An illuminated Transfer indicator confirms that the desired water controller is in control of the water delivery temperature.
If the Transfer indicator is not illuminated press the ‘Transfer’ button to transfer priority to the desired water controller.
The Transfer indicator on the water controller will now illuminate to indicating that priority has been transferred and that the water heater is ready to supply hot water once a hot water tap is opened.
Whilst hot water taps are open transfer of 'priority' between controllers is not possible. This is a safety feature.
HOT WATER CONTROL Temperatures higher than 50°C should only be able to be selected on the controller labelled ‘Master’ controller (used in the kitchen), not on those labelled ‘Bathroom’ controllers. This helps minimise the risk of burns.
The wireless transceiver has been incorrectly assigned if temperatures in excess of 50°C are able to be selected on controllers used in bathrooms, ensuites, toilets and laundries. Re-assign the wireless transceiver if this is the case. See “UN-ASSIGNING AND RESETTING WIRELESS WATER CONTROLLERS” on page 36 and “INSTALLING WIRELESS WATER CONTROLLERS” on page 34
USING CHILD LOCK FUNCTION
The Child Lock function is designed to prevent small children or the infirm from operating the wireless controllers.
To Activate the Child Lock
To activate the Child Lock function press the button for 3 seconds. The Child Lock indicator will illuminate to confirm that the function is now active. Once activated only the initiating controller can then deactivate this function?
To Deactivate the Child Lock
To deactivate the Child Lock function press the button for 3 seconds. The Child Lock indicator will go out to show that the function is no longer active.
Child lock only applies to the water controller initiating the function and can be activated / de-activated regardless of priority status or whether the water heater is in the ‘On’ or ‘Off’ condition.
While the child lock is activated only the ‘Child Lock’ control and the ‘Off’ control are functional from that controller.
When the water heater is turned ‘Off’ while Child lock is activated it can not be turned ‘On’ again from a controller where the Child lock is activated.
If the water heater is turned ‘Off’ whilst hot water outlets are open it can not be turned back ‘On’ until all hot water outlets have been closed.
Child lock is de-activated during a battery change or when batteries fail.

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.
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.
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.
Rinnai Australia 14 Operation Manual
* 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.
