Operational Safety Information
IMPORTANT
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their
safety. Children should be supervised to ensure that they do not play with the appliance.
To clean your water controller(s) use a soft damp cloth
with a mild detergent.
'2127 use solvents!
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.
Depending on the weather conditions and the length
of the pipe between the hot water unit and the
outlet in use, there may be a variation between the
temperatures displayed at the water controller(s) and
the temperature of the water at the outlet.

at all times whilst mains power remains connected.
As a safety precaution, if a Kitchen Water Controller's
temperature is set above 50°C, transferring and then
returning 'priority' to the Kitchen Water Controller will
result in a set temperature of 50°C being selected.
When 'priority' is returned to Water Controllers other
than the Kitchen the temperature will be 42°C.

GENERAL INFORMATION
IMPORTANT
Other manufacturers water controllers are NOT compatible with Rinnai water heaters. Water
controllers MUST NOT be used with any Solar Boost water heater. Rinnai water controllers
brought in from other countries are not compatible with Rinnai appliances sold in Australia.
Regardless of water controller installation, all Rinnai water heaters must only be installed by an
Authorised person.
Water controllers, transceivers and water heaters DO NOT contain user serviceable parts and
must ONLY be serviced and repaired by an authorised person.
Master / Sub Water Controllers & Associated Temperatures
Only one MC model water controller can be designated as the 'Master' water controller. This water controller is
QRUPDOO\XVHGLQWKHNLWFKHQDQGXVXDOO\KDVDPD[LPXPWHPSHUDWXUHRI&ZKLFKLVVXႈFLHQWIRUDOPRVWDOO
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.
Some additional conditions regarding Master Controller maximum temperatures apply when a wireless water
controller is used as the 'Master' water controller.
(i) Temperatures of 55°C or higher can only be selected on the controller designated as the 'Master' water
controller if the transceiver 'Max Temp' is also programmed to 55°C or higher.
(ii) The temperature of hot water delivered is always limited to the maximum temperature programmed into the
water heater itself. For example, if the transceiver maximum temperature is programmed to 55°C and the
water heater is limited to 50°C, the maximum temperature that the water heater will deliver is 50°C. In this
case 55°C will be displayed on the wireless Master Controller until a tap is opened after which the display will
revert to 50°C.
IMPORTANT
The water heater maximum temperature cannot be adjusted by the user. These adjustments can
ONLYEHFDUULHGRXWE\DTXDOL¿HGDQGOLFHQVHGWUDGHVSHUVRQ
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.

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 in accordance
ZLWK$11=6
• 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.

MUST BE installed at least 400 mm above the highest part of a sink, basin or bath.
• When cleaning your water controller use ONLY a damp cloth and a mild detergent.
For water controller dimensions refer to "Table 4. Appliance Dimensions - B Series & Universal
Water Controller" on page 37.
Communication Cables
Wired water controllers operate at an extra low voltage (12 Volts DC) which is supplied from the water heater,
a 10 metre long communications cable is supplied for connection to the water heater. 21/< Rinnai supplied
communication cables may be used.
Optional longer per metre communication cabling Part No. 92078609 is available from Rinnai.
NOTE
The per metre communication cable does not come supplied with spade connectors, spade
connectors are available from your local electrical component retailer.

UNIVERSAL WATER CONTROLLER (MC-601Q) INSTALLATION
1. Determine the most suitable position, refer "Location" on page 26.
2. Mark and drill 3 holes (mounting and cable access) refer to page 37 for water controller dimensions.
3. When running cable through the access hole ensure the connector end of the cable is located nearest to the
water controller (Fig. 1).
Carefully remove the cover plates from the water controller, using a screw driver (Fig. 2).
5. Connect the cable to the water controller. Feed any excess cable lengths into the wall cavity to avoid the
pinching of cables between the wall and the water controller.
