I just finished installation of an 80 gal Phoenix Light. I am pretty impressed with the unit, but I have some questions that don't appear to be covered at all in the manual, and I am hoping some of you can help shed some light on them for me.
1) No info in manual about what the "Warning icon" means. I assume it is always on when the temp is set above a certain level to warn about scalding, but I don't see info in manual.
2) DHW mode icon: Is always on and no info in manual about it... what is it?
3) When it kicks in, the fan seems to make a lot of noise during acceleration... when it gets to speed it is pretty quiet. Is this normal?
4) In test mode the flame icon show 3 levels (actually I get low and high but no mid as I ramp fan up and down... not sure why), but during normal operation it seems to always be full on. Does it not show when unit is modulated lower during normal operation? And does it always start in high and ramp down as it gets closer to temp?
5) The default difference in temp for unit to kick on is 8 deg. This seems like a lot... so the tank can get to 8 degrees below set-point before unit kicks in... if I drop this to 4 or 5, will it kick on at low modulation more frequently to keep water at temp? Or will it always start at HIGH and drop down? ie. trying to understand if the modulating level is tied to temp difference or not... trying to get a general understanding of the algorithm it uses.
6) Seems like the only drawback to ECO mode is slightly longer recovery time? Do all 3 modulation levels get reduced by 80% or just high level?
7) There is a t5 menu setting for maximum power percentage. It says this defaults to 80%. So does this mean when not in ECO mode the unit is running at 80% of 76K BTU? And in ECO mode it is at 60% or 64% or something like that? How do these two settings relate?
Any info those of you who have installed one can provide me would be greatly appreciated!
Thanks!
