I have a new installed Navien nhb 55.
I installed it myself and I’m trying to figure out the settings. Heated concrete slab in my barn.
Right now I was able to set it to Custom with outdoor sensor disabled. It heats SUPER slow. The supply temp only come out maybe around 75f and that’s after a while. Return temp starts at 45f because the slab is cold.
The unit also either times itself out and stops the burner, or my regulator freezes from it running for so long (but it’s only 20f outside so it shouldn’t right now).
When I turn the pump off and then back on the boiler doesn’t re-fire. I have to wait a long time for it to work again. Last time I let it sit over night.
Finally, I have no error codes showing.
My fluid is 80/20 glycol/water.
Thanks for any help.
