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 pipework 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 6 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.

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.
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.
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.

Operation Manual |
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°C* ( 60, 65°C HD models only )
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 on all installations. Rinnai water heaters can be programmed to deliver higher temperatures via the kitchen water 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.
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: |
All |
Only ONE MC-100V water controller can be installed. |
Models |
Up to TWO BC-100V water controllers can be installed. |

NOTE
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.
Temperatures higher than 50ºC should not be able to be selected on controllers installed in bathrooms, ensuites or toilets. This is to help reduce the risk of burns from hot water. If this is not the case, the controllers have been incorrectly installed. CONTACT YOUR INSTALLER.
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 or the pre-set limit when water controllers are not fitted, 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 (or the pre-set limit of the appliance).
