Electrical Connections
Below is the connection for the RS100. Please refer to the installation manual and Rinnai’s recommended
application guide for more details or contact Rinnai’s Engineering Department as needed
The RS100 will connect to terminals 20 and 21
•
Controller wire should be no longer than 164 ft
•
Controller wire should be 18 (AWG) Gauge
•
Controller wire should be shielded if near high
voltage (120 V or higher) or if a long distance-the
ground should be connected at the boiler (not at
the controller)
•
Mount the controller in the coldest area of the
structure
•
Do not mount in direct sun
•
Do not mount too close to a heat emitter (where
the emitter could falsely influence the controller)
•
Do not mount near lighting that could falsely
influence the controller
Outdoor reset sensor (included with boiler)
connects here. When power is first applied
to the boiler, if the outdoor reset sensor is
not connected, the boiler will not incorporate
any outdoor temperature monitoring
On/Off room
thermostat or
control (no
voltage, dry
contact),
jumping these
points will
cause the
boiler to fire if
there is no
RS100
connected. If
an RS100 is
connected at
terminals 20
and 21, the
boiler will
ignore these
terminals.
Connect the wires to
the back panel of the
controller. Ensure
wire ―A‖ from the
controller is
connected to
terminal 20 (wire
―A‖) on the Boiler.
Ensure wire ―B‖ is
connected to 21.
Release the tab at
the bottom of the
controller to
access the
connection points
Note
: If these are swapped the RS100 will
not exit ―Auto Set‖ upon booting.
