WATER TEMPERATURE CONTROL
MAXIMUM DELIVERY TEMPERATURES
Rinnai gas continuous flow water heaters are factory pre-set to various maximum delivery temperatures depending
on model and their intended application. For the majority of applications, the factory pre-set temperature is
appropriate. In the unlikely event this is not the case this setting can be increased or decreased by an authorised
person such as a licensed plumber.
This does not apply to "50 degree compliant" models. To meet the regulatory requirements the
maximum delivery temperature is factory set and sealed.
NOTE
For model specific information in regards to the factory pre-set temperature of your appliance
refer to "Table 3. Maximum Delivery Temperatures" on page 34. The appliance model number
can be found on the dataplate, which is located on the left hand side of appliance.
OPERATION WITHOUT WATER CONTROLLERS
Rinnai gas continuous flow water heater products do not use a pilot light. When installed and operated without
water controllers, the opening of any hot water tap will automatically start the appliance. Once water is flowing
through the appliance the burner will be ignited by electronic ignition and water will be delivered at the maximum
temperature that the unit is capable of delivering. As with conventional water heaters cold water will need to added
to reduce the temperature to the desired level. When the hot water tap is closed and water ceases to flow through
the appliance, the burner flame will be extinguished.
Rinnai WATER CONTROLLERS
Other manufacturers water controllers are NOT compatible with Rinnai water heaters. Rinnai
water controllers brought in from other countries are also NOT compatible with Rinnai appliances
sold in Australia.
NOTE
Water controllers MUST NOT be used with any Solar Boost water heater.
Water controllers are available as an optional extra. Wireless, Universal and Deluxe water controllers can be
used together and will function as described in the Operation Sections of this manual. Refer to "Water Controller
Configurations" on page 9 to confirm the maximum number and combination of water controllers that can be
fitted to your water heater model.
Location
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 1500 mm).
Water Resistance
The MC-601Q universal water controller is a water resistant device, however excessive exposure to water such as
immersion may result in damage to the water controller. Durability of water controllers is improved when positioned
outside of the shower recess.
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.
NOTE
AVOID direct exposure to water or steam as these conditions may cause a malfunction.
ALWAYS AVOID exposure to water when the battery compartment is open.
When cleaning your water controller use ONLY a damp cloth and a mild detergent.
