Just moved into a newly built house and they have this thing set at 120. You almost have to turn it entirely HOT in order to hop into a shower/bath. I appreciate the video man... it helps alot
Thank you so much for the great instructions… I just adjusted my Rinnai and we’re back in business with hot showers - subscribed!
Resolved my RU199iN temperature issue. Thanks Bob!
Quick and easy, thanks for making this video!!
Great video simple yet easy to execute!
Straight and to the point. Thank you
Thank you, you just saved my day with this information. I was like crazy figuring out how to raise the temperature more and thanks to this video I managed to do it, thank you.🔥💯
Thank you so much for your detailed instruction!
Thank you so much! Found all kinds of videos for units with the dip switches in the front but you were the only one who showed how to do it with this unit!
Thank you so much for your instruction. Worked perfectly.
This was exactly what I wanted to know. Thank you very much.
Wow I thank you !!! My builders are idiots!!! I moved it to 130 !!! My temp was 98 degrees I love you ❤️
Big thanks for this video!, worked like a charm!
Worked perfectly. Thanks!
Perfect instructions. Thanks!
Thank you! Easy, just as you said.
Awesome! Just what I needed! Well done!!!
You're welcome! Thank you for your feedback.
Will try it, I was frustrated also why it was stuck at 120. Thanks for the video.
This was very helpful, thank you. Ours is set to 115 and that’s just not hot enough
There are 2 buttons on the RUC98. Top button is A and bottom button is B. Had to do a little digging to find out as it is not in the manual.
Outstanding!!! Thank you sooo much!!!
you're incredibly genius thank you sir
Thank you! I followed this to bump it to 130, everything worked great. Hopefully tomorrow’s shower will be hot instead of just warm.
Wow Sir! Super easy. There was no issue with the water temperature until we got into Fall. When I take a shower now it feels like I am on a cloud in heaven!
Thanks a lot, very helpful
Thanks for sharing this 👍🏻
Super helpful and simple. Thank you. Also thank you for the “water will be hotter tip!” Haha😂
Thanks very helpful
Thank you!
Thanks for posting. Easier than the directions in the manual.
It is literally identical to the directions in the manual.
Thank you
thank you
Subscribed and thanks for sharing. I have the Rinnai recirculating tankless heater and it's not your typical tankless heater since the pump or fan is constantly on. Even if I disable the recirculation on the app it will automatically turn on again. I know one of the features is the scheduler where you can schedule to turn off and on during the day. My old tankless only turned on when hot water in the house is used, which I like. This tank's pump or fan seems to be on constantly and it's loud. By any chance do you know another way to disable the recirculation pump besides the phone app and scheduler? The recirculation pump supposed to give instant hot water, but I really don't like the noise.
It's annoying to even have to go through this. Thank you for your help.
Thanks Bob. 120 at my house is barely hot enough.
Thank you!!!
I love you. Thank you!
Great video. 120F is not hot enough for me. 130F is perfect!!!
You made that so easy! THANK YOU! It worked perfectly!
You're welcome! Thank you for your feedback.
Thank you sir
Thanks.
Thanks so much!!! This is great. My hot water line runs along a concrete slab and drops it's heat very quickly; is there a way to get above 140 degrees?
Worked like a charm, thanks! Is there a way to set it higher than 140? Just curious. 130 is plenty for me, I don’t even need the full 140, so I definitely don’t need even more than that. But like I said - just curious.
Thanks
Thank you, thank you, thank you, work like a charm the only problem is I dropped one of the darn screws.
Thank you!!
You're welcome! Thank you for your feedback.
I'm using the Control-R mobile app and after making this setting modification I can modify the temp using the app, but not manually. I'm guessing it's because I have the Control-R box connected to the heater but have found no documentation about that.
Thank you for the video.
Very helpful, why don't they do this when they do the initial setup? I bet this is a common problem that many people just live with.
As a single mom I have to do all the manly duties your instructions were perfect 👍
I rent a townhouse that's
Thanks very much for you video.
I just moved to a newly constructed house which has Rinnai V75e. It is outdoor gas unit and it does not have temperature controller installed. What are my options? Thank you
You will need to do some homework.
May I know what is the GPM level on this tank on yellow paper what is the high GPM it usually on the yellow paper that says energy guide
Is there a way to make the default LOWEST temperature setting lower than 98F?
Any videos on how to “flush” / drain this particular tank?
Is it ok to set at 140 ? Thanks again
Manual says to set switch 6 on dipswitch 1 to on in order to raise temp up yo 140. Is that an option to your method?
I have the Rinnai RU98. I went ahead and pressed the A button for second and there's no response what should I do next.
After following the steps mine would only toggle up to 125. Is there something I'm missing? thank you.
This is very helpful. Thank you so much! Is 140 the max?
Previously my rinnai was upped to 140 a year or so ago. It's felt mild lately even when at maximum in the shower. I looked and it's at 130. It let me 'button up' to 140, but I haven't felt much increase in temp when showering. It still says 140 now. It used to be I couldn't even have the temp holder on my shower at maximum, not I'm shivering if I step away from the stream with it at max.
Hi Jojo,
If the 'buttoning up' is still not working for you there may be a bigger problem with the unit. I'd recommend contacting Rinnai directly about the issue. They have a contact form on their website (see link below). Hopefully they can help you out because no one likes a cold shower

Maybe you're due for a vinegar cleaning
Hello , Do you know how come my tankless already140Fc, but the tempter only like 60fc?
Mine wouldn't go above 110. It's 199999btu unit. Would it be the same?
We did this a few years ago so thank you but in texas we lost power for a week and the heater seems to have reset to 120. Haven’t checked as it’s k the attic but would it lose its memory if out of power for a week?
Same thing happened here except power was out for like 10 minutes. I think it resets on power loss.
mine doesn't have any buttons inside! any idea how to raise the temp with no A or B buttons?
Does this void the warranty in anyway overriding the set temperature?
I don't think so because my installer showed me where the button to set the temperature was. I just forgot the instructions to change and my manual doesn't tell me the correct information.
I had a slightly different model. Mine had a series of numbers, 1-8, on a connector. I flipped the switch down for number six and can now increase the temp to 140. Just leaving this comment here in case anyone else doesn't notice an A button on their board.
I have the 1-8 as well but I have a
Upper 1-8(with yellow pegs)
Lower 1-8(with white pegs)
Each has the 1 peg pressed down. Which #6 did you hit(yellow or white) and did you touch either of the 1’s already pressed down or did leave them where they are and then pressed down which #6
@@spudwebb3837 Mine was the yellow switch
Mine has the buttons, but pushing them didn't change anything. So it was dip switches. Yellow #6
broooooo im at my bosses house rn you just saved me ty dude.
How to change the display temperature to celsius? Thanks.
If you haven’t figured this out. Hold the on off button for 5 second. Should switch
How do I change water pressure
Can I keep the temperature to 130 !
I new it could get hotter. The installers I had were dumb and didn't know.
I don’t see the A or B button on my Rinnai RL75 unit
Hi, it is not work on my model. I have MC-91-2US-V. any suggestions. Thank you so much.
Me too
Dip switch 6
Thanks. I was able to get to 130. But the temp keeps falling back to 120 automatically after one or two days.
How to permanently make it 130 please?
Are you pressing the priority button when you set the temp? The button tells the water heater that the controller you're touching has priority on water temp for the heater. Note that the priority can only be changed while no hot water is running. I was able to find more detailed instructions on the link here under "How to Set the Temperature" if you need further help: www.alpinehomeair.com/related/Rinnai%20LSe%20Series%20Installation%20Instructions.U287-1932x01(00).pdf
@@AlbanyCountyFasteners thank you for the video. I’m confused though. When you ask if they are hitting the priority button, does this mean they weren’t supposed to or they were supposed to. I’m going to be doing the same thing I just want to move it to 125, but do I need to press that priority button at some point, or else it will just go back to 120 in a couple days?
Will this get me hot water quicker? I find the only flaw with a tankless is the waiting. Otherwise it's great.
You won’t get hot water any faster than your previous hot water heater, unless you have a recirculation pump which keeps hot water criculating continuously through your pipes.
No, Coils have to heat the water.
We just moved yesterday to a townhouse condo and the heater the same as this but the highest water temperature is only 32 degrees with 140. It so cold for shower. Please help
Follow the process
Thank you so much for the reply. It was already set to 140 but the highest water temperature is only 32 degree celcius. It didn’t get hotter than that. I want more hotter, because 32 degrees is so cold for shower. Thank you
Mine won’t move when I push the a button
Mine didn’t either, but I figured out it’s because I have two tankless water heaters, running in parallel and only one control panel acts as the master for both. So if you have two running in parallel with the cross connect cable, try the other one and the guidance that he gave worked.
Hi,
I’ve tried this and mine doesn’t change anything on the screen with either button pushed. Mine looks like yours but doesn’t have everything on the plastic panel which the button is located.
It’s a RL75i model
Same thing happening here,did you ever figure it out?
@@waddo777dlc2 Yes. I called and the guy actually sent me the page that wasn’t in the book.
Is this safe? I’d like to know before I try.
How do you switch it to commercial mode to increase temp to 185°
You can’t
Switched it to no recirculation- goes to 185° with 1b and 2b set
Figured it out. It can't be in-use. Mone as at the time
i did this and now i have to let the water run for at least 15 minutes minimum to get hot water 140 but with in 2-5 minutes tops the hot watet cuts off and freezing water comes out
Mine does same
Yeah this happened with ours as well. Plumber here for 5 hours just determined that at 140 the unit overheats and shuts off...
@@margodunlap6345 THANK U i had just given up at that point TRUELY THANK YOU GUYS❤️
I pressed the A button but nothing happened. Any ideas?
My thermostat is dead and won’t even turn on?
I can't find any video on code 63 or way to fix it
I followed exactly but for some reason my water pressure dropped
my A button is not working i try pushing its not doing anything need help
Maybe give the model number next time???
Sir where is the button ?!
There is a plastic cover in the lower right quadrant of the heater corner. Carefully reach under that plastic to press the top black button. The top button is the "A" button he mentions. Then follow the rest of the instructions. Just be careful not to tear the plastic cover over the buttons. Works exactly as he describes.
I'm holding A button and nothing happens. Suggestions?
Poop
simple??? that stooped ! you need to remove panel , nothing difficult to remove the panel , but that’s 21 century . for me thats not normal
Thank you for your feedback.
Rinnai doesn't want to be responsible for scalding injuries. It's fairly simple to DIY since you only have to do this one time.
Most adults will suffer third-degree burns if exposed to 150 degree water for two seconds. Burns will also occur with a six-second exposure to 140 degree water or with a thirty second exposure to 130 degree water. Even if the temperature is 120 degrees, a five minute exposure could result in third-degree burns.
You should probably check your local codes before doing this you could be liable if a child gets hurt.
Thank you for your feedback.
You're totally right, when I take a 5 minute and 1 second shower at 120 degrees I always get third degree burns. For this reason I try to keep my showers to 4 minutes and 59 seconds. I'm going to go check my local codes ASAP!
Uhhh this comment has nothing to do with the video, many businesses use these
@@LundieF Your reply is golden lol. You're the best
LundieF 😂😂
Anybody else pissed off that you have to take a panel off and use a tech to do this? Anyone else pissed it takes gallons of water to start to heat the system up when their motto is "The smarter way to heat water"? Hey Rinnai - NOT HELPING. Just put an advisory on the front "Setting above 120 may result in scalding" and let us big boys and girls set our own water temp with the buttons thanks.
