You need to unplug the unit, wait for 30 seconds reset the temp to the lowest temp, then try it, if this does not work it might have done something to the circuit board, are you on a gfi out let it needs to be there is water and ele, and should be on the gfi with a reset on it,,

How to wire tempra 24 plus


1) Copy following link for wiring tankless electric water heater:
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html

2) Look at label on side of unit for total KW

3) Product manual shows 24 Kw or 24,000 watts
24,000 watts divided by 240 volts = 100 amps
So your service panel must be about 250Amp rating to support this tankless electric water heater.
http://waterheatertimer.org/pdf/Tempra_tempra-plus-Tankless-electric-water-heater-manual.pdf

4) Look inside the unit to see how many L1L2 terminals show.
You should have two sets L1L2 terminals
http://waterheatertimer.org/images/Terminals-2-tankless-200.jpg

5) You need TWO 60 amp double pole breakers to supply power to this unit.
This means you need TWO #6 wires from one breaker going to L1L2.
And you need TWO MORE #6 wires from 2nd breaker to other set of L1L2 terminals.

I do have noritz 0931m that some times work and some time not


The NC250 (N-0931M) Series ASME Tankless Water Heater is a commercial grade water heater and many people install the vent wrong. PVC CANNOT be used for venting. The NC250-DV-ASME is for indoor use only. Improper venting will cause the symptom you describe.

I would like to know the electrical requirements.( voltage and amperage) Does it plug in or is it hard wired? If the power goes out is the hot water also out? thankyou


Are you asking about tankless gas or tankless electric?

You posted under Tankless gas water heater: gas type tankless plugs into standard 120Volt household outlet to power circuit board. You need larger gas line than used for tank-type gas water heater.

If you are asking about volt and amp draw of Tankless electric, then that depends on specific model number.
For example, if each tankless element draws 3500Watts, and unit has 3 elements, you will need 3 additional 20 amp 240Volt circuit breakers. Volts x amps = watts. 3500 watts divided by 240Volts = 14.58 amps. At full blast, this unit would draw 43.75 amps and will cost more to operate yearly than tank-type electric water heater. If unit has 4500 watts elements, then it will draw 56 amps at full blast, and use a good percentage of household power.

Tankless water heaters have no hot water in power outage. This is true for gas and electric models.

No hot water? How can we reset?


This happens with Nortiz heaters. They just **** out. Likely the installation is very bad, but the unit can not tolerate that and it just dies. I recommend getting a Bosch 2700 or 715. If you want great efficacy, get the C-800. But follow the instructions! If it is installed correctly and you have the CO2 levels adjusted when it is installed, you will be very happy.

Water becomes ice cold in the middle of a shower


Sounds like you have a problem with water flow. Since your ground water is warmer in the summer, you mix less hot and more cold in order to get the same warm temperature. If your hot water flow gets low enough, your tankless will start to "short cycle" in order to prevent scalding. Use one of these three methods to increase your water flow at the shower:

1) Clean your shower head and descale
2) Widen the hole in the showerhead's flow restrictor
3) Remove your flow restrictor entirely

Good luck!
