SENSEI™ RXP PUMP PERFORMANCE AND PUMP + TANKLESS PERFORMANCE CURVE
Recirculation
Pump Control
- Smart-Circ.™ “learns” users’ hot water patterns to activate recirculation.
- Manual schedule selection is available with Accessory controllers (MC-195T or Wi-Fi module).
Internal Multi-Speed DC Pump
Integrated pump allows for recirculation through a dedicated return line or crossover with thermal bypass valve.
- 400 equivalent feet for 3/4 in. pipe diameter
- 100 equivalent feet for 1/2 in. pipe diameter
Maximum Recirculation Pipe Lengths
For dedicated return lines: Total length includes both hot water supply and
dedicated return lines.
Cross-over mode: Total length includes both hot water supply and cold
water piping length from the tankless water heater to the thermal bypass
valve. Cross-over mode requires the use of a thermal bypass valve (included).
