Rinnai Australia 9 Operation Manual
GENERAL WATER CONTROL INFORMATION
RADIO COMMUNICATIONS
Rinnai wireless water controllers are classified as short range radio communications devices and
referred to as Low Interference Potential Devices (LIPD’s) in AS/NZS 4268*. As such, they operate in
the same radio frequency spectrum as many other devices classified as LIPD’s such as garage door
openers and keyless automobile entry systems. Although interference with other LIPD's is unlikely, it
is not guaranteed interference will not occur.
Rinnai wireless water controllers must not be used in the vicinity of other devices if radio interference
with such devices could result in a dangerous situation, unless it is verified that interference will not
occur. Possible examples are medical devices and fire alarms.
*AS/NZS 4268 ‘Radio Equipment and systems – short range devices – Limits and methods of
measurement’.
WATER RESISTANCE
MAXIMUM DELIVERY TEMPERATURES
Rinnai 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.
Factory pre-set delivery temperatures for the various models are as follows:
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. 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:
Master Controller (used in kitchen):
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C* 60°C*, 65°C*, 75°C*
Bathroom Controller (used in bathrooms, ensuites, toilets and laundry):
Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Whilst hot water outlets are open the set temperature may be lowered. However the set temperature
cannot then be raised above 43°C. In addition transfer of 'priority' between controllers is not possible.
These are safety features.
The MC-503RC Wireless water controller is a water resistant device, however
excessive exposure to water such as immersion may result in damage to the
controller.
• DO NOT immerse the controller into water.
• 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.
This does not apply to “50 degree compliant” models. To meet the regulatory
requirements the maximum delivery temperature is factory set and sealed.
