2.7 WATER CONTROL

2.7.1 GENERAL INFORMATION

Only  one  MC  model  water  controller  can  be  designated  as  the  ‘Master’  water  controller.  This  water  controller  is 

normally used in the kitchen and usually has a maximum temperature of 55°C, which is sufficient for almost all kitchen 

applications. Temperatures higher than 55°C are possible but usually unnecessary and will result in higher gas use 

and increase the risk of burns.
The remaining water controllers are designated ‘sub’ controllers and are for use in bathrooms, toilets and laundries. 

The temperature limit for all ‘Sub’ controllers is always 50°C to minimise the risk of burns in these areas. 
An installation can have up to 4 universal MC-601 water controllers.
Deluxe kitchen and deluxe bathroom water controllers are also available and various combinations of universal and 

the deluxe water controllers can be used with the following limitations:

• 

A maximum of 4 water controllers can be fitted.

• 

Only 

ONE

 master controller can be installed. This can be a deluxe kitchen or an universal (when programmed 

as a master controller) water controller.

IMPORTANT

When a deluxe kitchen is fitted it will always function as a master controller, this is the default 

setting and can not be changed. 

• 

Up to 

TWO

 deluxe bathroom water controllers can be installed.

• 

The 

FOURTH

 water controller in any installation must be an universal water controller.

For more information regarding deluxe kitchen and bathroom water controllers, contact Rinnai or visit: www.rinnai.it.

Location

NOTE

• 

Do not install water controllers near a heat source, such as a cook top, stove or oven. Heat, 

steam, smoke and hot oil may cause damage. 

•  Do not 

install  water  controllers  outdoors  unless  protection  from  water/dust  ingress  and 

sunlight are provided.

• 

The water controller set as the master water controller must not be installed in a bathroom.

•  Do not

 

install water controllers in direct sunlight.

• 

Do not install water controllers against a metal wall unless the wall is earthed.

• 

Water controllers must not be installed where chemicals such as benzene, alcohol, turpentine, 

hydrogen sulphide, ammonia, chlorine or other similar chemicals are in use.

The Water controller is a water resistant device, however excessive exposure to water may result 

in  damage  to  the  water  controller.  Durability  is  improved  when  positioned  outside  the  shower 

recess.

• 

Avoid direct exposure to water or steam as these conditions may cause a malfunction.

• 

Water controllers must be installed in shaded and clean locations. They should be fitted out of 

reach of children (suggested height from floor to be at least 1.5m). Water controllers must be 

installed at least 40cm above the highest part of a sink, basin or bath.

• 

When cleaning your water controller use only a damp cloth and a mild detergent. 

Communication cables

Wired water controllers operate at an extra low voltage (12 Volts DC) which is supplied from the water heater, a 10m 

long communication cable is supplied for connection to the water heater. It is possible to prolongue the communication 

cable by using a similar one, up to a total max length of 50m. It is not recommended to install the communication 

cable near by house electric cables: interfearence may easily happen causing system malfunctions. In these cases we 

recommend to use proper shieldied cables.
When  connecting  the  cables  to  water  controller  or  heater  the  polarity  is  not  important:  either  colour  wire  can  be 

connected to either terminal.
