Temperature Control
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.
Only one MC model water controller can be designated as a 'Master' water controller and this is normally used
in the kitchen. All the remaining water controllers are designated as 'Sub' water controllers and are for use in
bathrooms, toilets and laundries. The maximum temperature limit for all 'Sub' water controllers is restricted to 50°C
to minimise the risk of burns in these areas.
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:
Water Controller
Temperatures (°C)**
For hygiene in sanitary areas such as bathrooms, the suggested temperature should be 37°C ~ 43°C.
The above is a suggestion only, as you may find higher or lower temperatures more comfortable, however
maintaining lower temperatures also helps to save energy.
To obtain water temperatures lower than 37°C, simply open the cold water tap and add cold water until the desired
lower temperature is reached.
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
NOTE
will automatically go out� The 'in use' indicator
once the outgoing hot water temperature falls to that shown on the digital monitor (or the pre-set
limit of the appliance)
* Temperature may not be available on all installations� Some Rinnai Continuous Flow water
heaters can be programmed to deliver higher temperatures from the master water controller, or
may be programmed to restrict the maximum available delivery temperature� Contact Rinnai for
more details�
** Temperature limiting devices (where fitted) may further control what maximum delivery
temperature is available to outlets�
Universal and Wireless and water controllers allow temperature selection only. Deluxe water controllers allow
temperature selection, have a clock function and the Deluxe Bathroom water controller has a shower saver / bath
fill function is also available, contact Rinnai for further information regarding Wireless and Deluxe water controllers

WATER CONTROLLER COMBINATIONS & CONFIGURATIONS
Wired Only Configurations
•
A maximum of 4 water controllers can be fitted. Any combination of deluxe and universal controllers can be
used with the following limitations:
•
Only ONE master controller can be installed. This can be a MC-100V, or a MC-601Q (when programmed as
a master controller). Note that when a MC-100V is fitted it will always functions as a master controller, this
is the default setting and can not be changed.
•
Up to TWO BC-100V water controllers can be installed.
•
The FOURTH water controller in any installation MUST BE a MC-601Q.
Combined Wireless & Wired Configurations
•
A maximum of 4 water controllers can be fitted. Any combination of deluxe, universal and wireless controllers
can be used with the following limitations:
•
Only ONE master controller can be installed. This can be a MC-100V, a MC-601Q (when programmed as
a master controller) or a MC-503RC-S water controller. Note that when a MC-100V is fitted it will always
functions as a master controller, this is the default setting and can not be changed.
•
Up to TWO BC-100V water controllers can be installed.
•
The FOURTH water controller in any installation MUST BE a MC-503RC-S or a MC-601Q.
