2.11 RECIRCULATION MODE
The Rinnai Infi nity SENSEI Series water heater has the ability to control a recirculation pump (optional), with a
connection cable supplied separately. With this optional mode is possible recirculate the water in the plumbing system
to provide hot water quickly when a tap is opened.
Two modes are available, “Economy” and “Comfort”. Recirculation mode is for residential installations only, this mode
cannot be used with the Bath Fill controller (BC-100), or with multiple Rinnai water heaters. The maximum Rinnai
temperature setting while in recirculation mode is 60°C.
2.11.1 INSTALLATION
Pump
•
Voltage: 230V AC, 50 Hz
• Amperage: < 2Amp
•
In-rush current: less than 2.5 Amps.
•
Check valve: an integral fl ow check (IFC) valve is required. See plumbing
diagram.
NOTE: The Rinnai PC board will be damaged if amperage exceeds 2 Amps.
•
The pump should be sized for 10 L/min at the pressure loss through the tankless
water heater and the supply and return plumbing in the recirculation loop. For
more information on sizing the pump refer to Rinnai.
Installation procedure
1.
Turn off the electrical power supply by unplugging the power cord or by turning
off the electricity at the circuit breaker.
2. Install the recirculation pump on the return line according to the pump manufacturer installation instructions.

The connector pump (supplied separately) has a black and white wire, to connect to the pump, cut the
connector, splice the wires and add 4 Amp fuse to the hot wire (black) of the pump.
4.
Connect the ground wire from the pump to a screw at the base of the water cabinet (refer to the pump electrical
connection diagram). Follow the electrical code and pump manufacturers recommendations.
5.
Connect wire harness must in the correct port on the PCB; the pump connection port is located at the bottom
of the PCB, in the middle. (Fig. 1).
