Programming Your Noritz NRCP Part 1 (Demo)

Setting the Time and Date

Want to save on energy costs and enjoy unlimited hot water when you need it? One of Noritz’s most high-efficiency and function-rich products is the NRCP line of residential tankless water heaters.

Usually, no matter what kind of water heater you have, there is a wait for hot water as it travels through the pipes to the outlet, such as a shower head. The NRCP line of heaters, however, can couple with an external water recirculation system to bring you instant hot water.

How to program your NRCP Part 1

In recirculation systems, a circulating pump that is external to the tankless water heater moves hot water through a pipe “loop” created in the plumbing system of a home or building. In addition to supply lines connecting the water heater to each outlet, a recirculation system also contains either a return line back to the heater from each hot-water outlet or from only the farthest fixture.

An added feature of the NRCP is its internal circulation pump, which regularly circulates about half a gallon of warm water inside the unit, with a temperature sensor turning the burner on or off. This prevents freezing if the unit is not in use for an extended period during the winter. It also makes the water heat up more quickly, since it’s already quite warm, allowing for an even shorter wait at the hot-water outlet.

Below, we discuss the basics of setting the date and time on your NRCP.

Setting the Date and Time:

  1. Lift open the window panel located towards the bottom of the unit.
  2. Press the Power button to turn on the unit.
  3. Press and hold the Function button for five seconds to enter the user mode.
  4. The A:GA mode will appear. You’re now able to scroll through the different options by rotating the Dial button to the right.
  5. Once you reach the L:TA mode, press the Dial button to select. This area will let you change the time and date, starting with the year.
  6. Rotate the Dial and press to set the correct year. You will then be able to do the same to set the month, day, hour and minute. To skip past one of the time intervals, press the Dial (Note that the NRCP unit uses military time, meaning a 24-hour time frame; e.g., 1:00 p.m. is expressed as 13:00.)
  7. Once you’ve set all of the options, you should automatically return to the L:TA mode. From here, press the Function button to return to the home screen where it will indicate the time of day.

An upcoming blog will examine how you can program your NRCP to recirculate water only at certain times of the day. For more information on the NRCP, please visit https://www.noritz.com/nrcp/.
