General Information
Location and positioning
Distances
Distance between water heater and transceiver must not exceed 20 m.
The water controller and transceiver should be fitted out of reach of children, suggested
height from floor to be at least 1.5 m. They must also be installed at least 400 mm above the
highest part of a sink, basin or bath.
Sunlight and LCD display
Do not install wireless controllers in direct sunlight as light reflections make the LCD
difficult to see at eye level. Mount lower than eye level to avoid these reflections.
Chemicals and heat
Do not install near:
a heat source such as a cook top, stove or oven
where chemicals such as benzine, turpentine, hydrogen sulphide, ammonia, chlorine or
similar chemicals are in use

Specific to water controllers
They must be installed in a clean and shaded location. They are water resistant, however
durability is improved when positioned outside the shower recess. Refer next page for further
details.
Signal strength
Take signal strength into consideration when determining the best location for the
transceiver and controller. In some cases building construction and design can reduce
signal strength.
It may be necessary to locate the transceiver in a central location inside the building. For such
locations extended lengths of communication cable are available from Rinnai. alternatively
double insulated flex with a minimum area of 0.5 mm
2
may be used.
Metallic structures, appliances or magnetic fields in the vicinity of the transceiver or controller
may reduce signal strength.
The transceiver’s atenna is located in the top. For best results mount the transceiver so the top
is higher than the top of the water heater. If mounted to the side or below the water heater
the signal strength may be reduced. The transceiver may be mounted inside a metal recess
box or pipe cover, however this may reduce signal strength. aLWayS test the signal before
permanently attaching the transceiver and controller.
The signal strength indicator for the wireless water controller should be at least 2 bars
during installation.
