    Navien NPE240A- Navilink,Navilink App, Recirculation settings And Parameters

    Glad this thread was able to help you-- The app could really use clarification and a reboot. The enable/disable work around for a hot button really speaks to the fact that they could just make an app based digital hot button alone-- with a timer better yet to resume the normal schedule. One...

    Navien NPE240A- Navilink,Navilink App, Recirculation settings And Parameters

    I agree with Spacecowboy-- The information I have refers to external recirculation with cold water line return, but I expect the settings would be the same with a dedicated return line. dip one off, dip 2 on, everything else off (down is off) I can send a copy of the Bulletin -- but I can't...

    Repair for a Shower floor

    Thank you for these great suggestions, I like the idea of the self leveling crack sealent. I was planning to use simple grout brand as it is a flexible grout. "worth florida" recommended siliconized latex sealant so that the new grout would stick to it. Does anyone have any idea if flexible...

    Repair for a Shower floor

    Thanks for your reply. Pan was hand done 15 years ago. Plywood floor over joists. Not sure if there was a cementboard laid first- but I doubt it. Complete rubber membrane clamped to drain. Dry packed mud pan, thinset, tile. I can see the bottom of the drain from underneath- I see no sign of...

    Repair for a Shower floor

    Photos attached: There seems to be a fault through my shower floor and separation of the grout along those lines. Closest to the wall I know some water accumulates under delaminating tiles. I have cleaned off the "fault" line with CLR. Hoping to find a fix with out removing the entire floor. I...

    Navien NPE240A- Navilink,Navilink App, Recirculation settings And Parameters

    If the hot button is not engaged, or a schedule is not specified and enabled in the app then the water heater simply will not re-circulate. Quote Have you tried creating a schedule but then disabling the schedule? With a specified schedule if I then disable the schedule my unit will run...

    Calibrating Navien NPE240A

    Yes, You are all correct-- it is calibrated in my head-- that said I was just curious if there were a setting where calibration could be adjusted. I would think that tested at the factory some calibration must be done. Thanks.

    Thanks for your replies. I understand there will be heat loss. I simply want to calibrate the machine reading with the actual temperature at the farthest fixture-- if there is a way. Thank

    Calibrating Navien NPE240A

    When my Navien NPE 2401 tankless water heater is set to 120 degrees F I get 115 degrees at my farthest fixture. Set at 125 degrees I get 120 F at my farthest fixture. It there a way to calibreate the temp on these units-- I see nothing in the Manuals. Thanks

    Navien NPE 240A— Navilink recirculation—some customer insights. I have had The Navien NPE240A for about two years now and the unit has worked flawlessly, but it has taken me a while to get my recirculation settings working and recirculation parameters dialed in. I thought I would share here...

    Navien NPE 240A Parameter list.

    No worries Dana and thank you again. I understand what you are saying and it makes perfect sense. That said I feel that my changing the parameters has helped. While it can not prevent the delay in cold water being heated when called for ( as you have explained) I feel like I am softening the...

    Questions about Navien NPE-240A recirculation

    Above is a list of the parameters. I have The NPE 240 A-- about 2 years old 2017. I can not tell you what to order if yours is different, But what you say makes sense. In my situation to set up scheduled recirculation all I needed was the Navilink and The APP. Note. As of this writing if you...

    In response to zl700 thank you for the parameter list.In response to Dana, Thank you for responding. I have read the manuals thoroughly .

    Navien NPE 240A Parameter list.

    I finally have my Navien NPE 240 A scheduling working, but I want to tweak the parameter settings to try and get the hottest water to my farthest fixture and keep it hot during the scheduled recirculation times.
