Rinnai New Zealand i Operation Manual:01-07

Controllers and water heaters must be installed correctly by an authorised person. The installation of
gas, water, and electricity must conform to local regulations.

The installation must also comply with the instructions supplied by Rinnai.

Please keep this instruction booklet in a safe place for future reference.

All dimensions referred to in these instructions are in millimetres, unless otherwise specified.

Excessively hot water is dangerous, especially
for young children and the infirm. Rinnai water
heaters allow you to control the temperature of
hot water to safe levels.

Water temperatures above 55°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 (the
average hot water temperature in New Zealand)
can severely burn a child in less than half a
second. At 55°C it takes half a minute.

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 55°C (Contact Rinnai New
Zealand).

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.

GENERAL WATER CONTROLLER INFORMATION

Temperature 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°C, 65°C, 75°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 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 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 Controllers allow temperature selection only. Deluxe controllers allow temperature
selection, 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-91-2A) and Deluxe (MC-100V & BC-100V) Controllers - available configuration:

A maximum of 4 water controllers can be fitted. Any combination of the deluxe, universal and wireless
controllers can be used with the following limitations.

Only ONE master controller can be installed. This can be MC-100V, a MC-91 (when programmed as
a master controller) or a MC502S (wireless) controller.

Up to TWO BC-100V water controllers can be installed.

The FOURTH water controller in any installation MUST BE a MC502S (wireless) or a MC-91.
