My experience, 3 years on is the unit runs in Normal mode in the daytime (with Boost just for manual boost post shower/bath) and at night I run it at 3% tickover (so minimal noise) - with the bedroom windows open. So balance it for Normal/At Home. Boost I set at a happy medium of being functional and not too noisy. Footnote: if you have a (sealed) log burner as I do I would encourage you to have a positive pressure in the space around the log burner as when opening the log burner door you don't want to suck the fumes out. Ours could do with a tweak, as we have to slowly open and shut the door to not create a stink.

Well after rebuilding both stacks, with new lime mortar and applying a water sealant in early 2020 - it now looks mighty ugly (on both stacks) and I still have concerns of internal damp - hoping to get an expert out and will see how it fairs this winter

Finally (well about two years after the conversion was completed) I've managed (to find someone else) to trawl through the hours of video to create a 12 minute time lapse of an old barn on our family farm to holiday cottage conversion! See here https://youtu.be/xJuw4Q1SYrs We remain indebted to BuildHub for the support (mainly with the Sunamps) - thanks all

These four LEDs?

Cheers if I have to get an electrician to disturb this box again I'll pass on the comments - for sure cable markers or even a scribble on the inside of the box lid would have been very handy recently!

Correct

Like the PCM58 I have the PCM34 has a series of 4 led lights on the left of the control board, located between two buttons. What do these lights mean when on/off Thanks Paul Read Rigsby Wold Holiday Cottages

Upgraded relay installed, seems to be working fine.

Thanks @Andrew Bissell - Sunamp much appreciated. Not sure I count the invoice date as the start of the warranty period but however I appreciated the upgrade part being sent - which my electrician has just swapped the unit over too. My primary concern is not having my future customers experiencing a loss of hot water (and potentially leaving a negative review) in two or three years time I'm assuming the upgrade relay resolves that.

With spade connectors, Sunamp warn me this one also has visible sparks from the internal contactors

Upgraded relay received from Sunamp, now need to get electrician back out to install it.

Correct, having spoke to Sunamp they say that is normal!

Sunamp say they are going to send me a new relay, they say they considered the Finder relay fine and therefore no need to contact existing customers! I'll be sent the latest spec - though it was unclear what that is going to be. @Jeremy Harris Have you a picture of your replacement relay please ?

Not ideal I reckon 20200726_210049.mp4

This issue was two years ago and in a number of places (and with the multiple additions of extra top soil and seed) we finally have the grass up to the edging stones. Still some patches needing further attention though

Got a call from our holiday cottage - guests no hot water. Thanks to @Nickfromwales support was quickly able to identify control main relay failure exactly as @Jeremy Harris I believe - with the neutral line remaining open. Horrified to see it spark through the relay body and very annoyed no proactive input from Sunamp telling me to replace the relay so now got an expensive electrician call out for a short term replacement relay to get hot water flowing again - argh!

Gosh! I know how must be feeling. I'm still trying to teach my 8 year old boy after nearly 3 years living in my house to try and walk gently on the first floor as it flexes so much. Not ever checked the level though, not to worried about that, more concerned about sag - dare not check that. Got no where with the builder, floor joist supplier, floor joist software developer all passing the book. Still peeves me I'm just glad my home office is in a different part of the house and we are rarely upstairs except for sleeping

These 4 steps are exactly what I did! At night I have the unit set to 3% to reduce the noise and open a window!

Moving it would not resolve the issue - just giving a different property a noise issue. Sound fencing certainly seems the most viable option the only trouble is that it needs to easily removal and replaced as they is very little space between the fan entrance and the barn door entrance and we need all that for grain loading.

Budget is £1000 so not intending to replace unit (at this stage)

It is difficult to block out the dates as when the harvest comes in can vary +/- a couple of weeks and if the wheat is wet or hot then we need to run the fan when ever the weather lets us so can easily be a few months of on and off use. Yes it is a 37kW fan. Bearings seem ok when I did a quick test the other week. I'll give the blades a good clean and see if that improves it.

The plate says: 1450 rpm 37 kW 400 V 70 A 50 Hz 3 phase Rewind (and probably last time balanced etc) 28/10/2011 Though watching the fan slow down to stop it seemed very well balanced. I believe there are 12 blades from looking at this pic: I used an Android app called Recorder with high quaility enabled on a Samsung S10 this created an AMR file that I opened in Audacity using the FFMPEG extension and applied no filtering.

We had opportunity to run the fan over Xmas. Using my Android phone and Audacity I gathered this spectrum. Taken with the phone close to the input of the air to the fan. I also did a recording with the phone held directly on the electric motor body but felt this was the less noisy side. Quite hard to say as my ears are so full of sound I could not truly say which was the louder side! I welcome any analysis of this frequency plot as I'm not really sure what there is to learn from it. Thanks
