WARNING ABOUT HOT WATER
Heated water can be dangerous, especially for young
children and the infirm.
Water temperatures above 50°C can cause severe burns
instantly and may even result in death.
Those most at risk are children, disabled, elderly and the
infirm.
Hot water at 65°C (a very common hot water temperature in
Australia) can severely burn a child in less than half a second.
At 50°C it takes five minutes.
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 1 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 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.
• 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.
• 'Deluxe' or 'Universal' Water Controllers are 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 7 for details.
• Water controller cables are connected easily by the end user using a convenient quick connect
system.
• Operating NOISE LEVEL IS VERY LOW.
• ERROR MESSAGES ARE DISPLAYED on the Water Controllers and Status Monitor*, assisting with
service. *Status Monitor available on INFINITY 26 Plus (REU-VRM2630WD), HD250e (REUVRM3237WC), HD200e (REU-VRM2632WC) and HD200i (REU-VRM2632FFUC) models only.

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.

Kitchen
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.

GENERAL WATER CONTROL INFORMATION
Remote 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:
Kitchen Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55*, 60*, 65* and 75°C*
Bathroom Controller:
Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Bath fill Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48°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 water controllers is not
possible. These are safety features.
Suggested temperatures are:
Kitchen 50°C ~ 55°C* Shower 37°C ~ 43°C, Bath fill 39°C ~ 45°C
* Temperature may not be available refer to “Delivery Temperatures”.
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.
Water controllers are an optional extra. 'Universal' and 'Deluxe' water controllers can be fitted.
Universal water controllers allow temperature selection only. Deluxe water controllers allow
temperature selection, shower saver / bath fill and have a clock function.
Water controllers allow the water temperature to be set from the various locations where they are
installed. The temperature selected will be available to all outlets.
Universal (MC-91Q) and Deluxe (MC/BC-100V) Water Controllers - available configurations:
A maximum of 4 water controllers can be fitted. Any combination of both deluxe and
universal controllers can be used with the following provisions:
