Water Controller Combinations & Configurations - Rinnai Infinity 20 External Operation And Installation Manual

Controllers must be installed at least 400 mm above the highest part of a sink, basin or bath.
Do not immerse the water controller into water.
IMPORTANT
Avoid direct exposure to water or steam as these conditions may cause a malfunction.
When cleaning your water controller use only a damp cloth and a mild detergent.
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:

temperature available after PCB settings adjustment.
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.
Universal water controllers allow temperature selection. Deluxe water controllers allow temperature selection, have a
clock function and, Deluxe Bathroom water controllers, have a shower saver/bath fill function.

1.3.4 WATER CONTROLLER COMBINATIONS & 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-601 (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-601.
When multiple temperature controllers are used they allow the temperature to be set from various locations by pushing
the transfer button which gives that controllor priority over the system.
The temperature selected by the controller with priority will be available to all outlets.
