• Additional wiring can run up to 300 feet (91 meters) away
from the water heater to ensure a strong wireless signal
(18-22 gauge wire is required).
• For outdoor water heaters, the module must be installed
indoors.
Basements, crawl spaces, attics, garages, and
mechanical rooms may have poor wireless signals.

sensor package.
Mounts in a
convenient
location (such
as a kitchen faucet or
bathroom sink) and
operates the recirculation
system by pushing the
button.
Motion Sensor
Mounts flush to
the wall or in
the corner and
operates the recirculation
system with the detection
of motion. Designed to
detect full-body movement
up to 30 feet.

• Push Button - Requires two CR2450 watch
batteries (included with push button)
• Motion Sensor - Requires one 2600mAh AA size
Lithium-Thionyl Chloride battery (3.6V or 3.7V)
(included with motion sensor)
Pair the Push Button or Motion Sensor to the module.
You Will Need:
• Control-R™ Module
• Push Button and/or Motion Sensor
• Phillips Head Screwdriver (Motion Sensor only)
❶
❷
Ensure the module LED has been solid red for at least
one minute prior to beginning the pairing process.

You have five minutes to pair the push
button or motion sensor with the module
before pairing mode times out.
Press and hold down the Connect button on the
module until the LED turns solid GREEN.
Then, release the button (you will need to repeat this
process to pair each accessory).
• Press and hold down the button
until it flashes three times.
• Release the button.
• If paired successfully, the module
LED will return to the previous
color.

• Use a Phillips Head
screwdriver to remove the
front cover.
• Press and hold down the
Connect button on the PCB
until the LED double flashes
every second.
• Release the button.
• If paired successfully, the
module LED will return to the
previous color.
When a push button or motion sensor is activated, the
pump turns on and runs for five minutes or until the
selected water temperature is reached (whichever occurs
first). The pump turns off and enters into a dormant
(inactive) state according to the parameter settings/dip
switches selected in the water heater. During this time, the
pump will not turn on for any reason, even if the push
button or motion sensor is activated.
Refer to the tankless water heater installation and
operation manual for more information on Circ-Logic
(Rinnai’s recirculation technology) and recirculation
parameter/dip switch settings.
IMPORTANT

Install the push button or motion sensor near the
water fixture that will be used frequently, such as a
kitchen faucet or bathroom sink.
Refer to the instructions in the push button or motion
sensor package for detailed installation steps.
Mount flush to the wall or
in the corner between
6 to 9 feet (1.8 to 2.7 m)
above floor level.
Adhere to any wall or
counter service using the
adhesive backing.
