Thought I would just give some updates.<br /><br />I do flush it every year, check the filters and check the pressure in my expansion tank. The expansion tank is needed in my case because I use the recirculation. I use straight supermarket vinneger and circulate for about an hour. The water in may area is good, but most pros I have spoken too feel that the flush will prolong the unit.<br /><br />Note: There is a sump drain on the bottom of the unit that I do not believe is discussed in the maintainece manual. Slipping out the metal clip allows you to pull it downward and I have found more muck and debree in their than in any of the filters. The o ring goes on the top edge of the sump insert and I would suggest you have a backup handy. If not seated evenly and correctly it will leak.<br /><br />The APP update : I still do not know whether they have accounted for Daylight savings time-- I will find out tomorrow a as the clocks move forward tonight.<br /><br />They still have not fixed the enable/disable wording despite a recent cosmetic update to the app. When the slider is orange the scheduler is on.<br /><br />Still no digital hot button, but if you turn off the weekely schedule (n Not orange) it acts like a hot button and the unit goes into its automatic recirculation mode. Just remember to turn the schedule back on or it will continue its generic 24/7 cycling.<br /><br />I get warm water sandwiches, but not so much cold during recirculation cycles. The unit always passes some cold water while it blows out the exhuast before starting. My long run of pipes likely heats that to warm along the way when circulation is called for. Under Dradam there is a discussion of my paramater setting in Terry loves plumbing forum. <br /><br />I have never had trouble connecting to my wifi, but parameter 18 must be on for the unit to communicate with the NAVILINK. When in AP mode you have to fill in data fast or ap mode kicks out and you have to start again. I am cat 5 hard wired but it works for me wirelessly as well.<br /><br />Odd note: Started having some moderate mold growth toward the top of my bathroom and finally realized it began after the Navien was installed. Endless hot water means more moisture despite my vent fans so beware.<br /><br />Hope this continues to help someone.<br /><br /><br /><br /><br /><br /><br /><br /><br />Dradamnoreply@blogger.comtag:blogger.com,1999:blog-5834591349436314089.post-25964510771614565402022-05-14T16:54:03.856-04:002022-05-14T16:54:03.856-04:00May 14 2022.

After much frustration getting the app installed and setting a schedule, we are unsure whether the app is actually communicating with the unit according to the schedule. In reading the comments there seems to be confusing information as to whether the schedule button should be set to ENABLE or DISABLE. Can anyone clarify? We do not have a hot button.<br />Also any suggestions on other troubleshooting actions we can try to be sure the two pieces are actually communicating?<br />Our installer has been on the phone with tech support multiple times and received no real guidance or solutions.

To correct it put your navilink in AP mode Add a new device with a changed name following the menus in your app (quickly or the navilik will go out of ap mode) and then delete the old name and the time will be correct in the device you you just created. Your settings are not lost.<br /><br />I have been tweeking my parameters a bit to try to maximize hot water in the pipes during a recirculation (cold water recirc system)-- adjusting time between sampling temp and time of recirulation. Still get occasional warm sandwich but overall 4 seconds to hot water at my farthest fixture during a recirculation cycle.<br /><br />Wish Navien would address DST, label enable correctly and create an easy software hot button !! Some guidance on the parameter tweaks would be nice as well.<br /><br />Hope this helps.dradamnoreply@blogger.comtag:blogger.com,1999:blog-5834591349436314089.post-91653808416454032812020-10-09T11:05:24.919-04:002020-10-09T11:05:24.919-04:00Thanks for the comments folks.

I was previously using the unit without any remote controller and in the "intelligent preheating" setting but found it to be recirculating in the middle of the night. I appears it is not that intelligent....<br /><br />It's just a bit frustrating that I need to have a plumber ($$) come set the dip switches as opposed to Navien providing the information directly. Going to search a bit more and see what I can find. Maybe I need to invest in the Navilink system.<br /><br />Thanks.Anonymoushttps://www.blogger.com/profile/00883496562284011924noreply@blogger.comtag:blogger.com,1999:blog-5834591349436314089.post-68993067016722597472020-10-08T18:00:04.516-04:002020-10-08T18:00:04.516-04:00Your question is two parts:

To do this you must have a water flow valve inside the unit set to "ext"for external circulation and and in "patrameter" settings option 2 must be set to thermal bypass valve "on".<br /><br />As of naviens technical bulletin updated march 2018 dip switches are 1-off(down) 2Up(on) and everything else off (down)<br /><br />2)Nr-20 Du--- I do not have this controller. I have the wireless navilink. To enable navilink control parameter 18 must be set to "on". I dont know if your controller works the same way.<br /><br />To access the parameters menu you must shut off the unit then hit up (+) three times down three (-) times and up (+) four times again. then use the up/down buttons to enter parameter mode-- not Tec. <br /><br />Hope this helpsdradamnoreply@blogger.comtag:blogger.com,1999:blog-5834591349436314089.post-65929556312351443372020-10-08T16:38:35.095-04:002020-10-08T16:38:35.095-04:00Interesting reading these comments.

So I purchased a NR-20DU remote controller to gain the programmable recirculation feature. Called Navien to find out what/if the dip switch settings should be when using the controller and they will not give them to me as the homeowner. Apparently this information is only for a licensed contractor.....sigh. Can anyone lend some guidance as to what the recommended dip switch setting should be? It is not in the manual.<br /><br />Thanks in advance Anonymoushttps://www.blogger.com/profile/00883496562284011924noreply@blogger.comtag:blogger.com,1999:blog-5834591349436314089.post-51636268089318447522020-06-21T18:59:41.704-04:002020-06-21T18:59:41.704-04:00Thanks for the replies.

What if I had recirculation off or a non recirculation unit? In those cases the water would do just that, right? I may test that by turning dip switch 2 off.<br />It seems unnecessary to use that electricity. And also my pump makes an odd noise like a groan at the end of each recirculation cycle. It's a bit of a bother to hear it.

So when you request hot water, it’s going to start the pumps to make sure that water stays heated as it passes through.

Are you sure it is the pump running and not the blower for the heat exchanger? that fan will come on when water is called for and go off a bit after the call has stopped.<br /><br />You may be correct though-- when you call for water it comes from the outside source and maybe the temp difference triggers the recirculation? That would make sense to me if you are calling for water during a scheduled recirculation interval. Have you tried it outside of a scheduled recirculatian?<br /><br />I would be interested if anyone has a definitive answer.

It may not run the entire time but it does run. <br /><br />For example: If I turn on my hot water faucet, I can hear the pump start and run. I get hot water right away since recirculation mode is on. If I turn the faucet off and wait until the pump stops, then turn hot water on again, the pump runs again. Is that necessary and normal?
