Hello,

Installed my Samsung gen 7 8Kw heat pump recently and it seems to be running well. I have finally got the app to work thanks to much help from Glyn and others.so I can see some results but cannot see how to add and share my results to get comments which will help answer some questions I have?

Can anyone guide me? Thanks

Peter

Here on this page? What exactly can’t you do?

You’re a ‘Basic user’ so you should be able to. If you click the ‘Upload’ arrow in the top margin of the box you type in, you can select a file and it will attach to your post, or you can drag-and-drop.

It’s the 7th from the left. Some file types are not allowed - so either zip or rename the file.

Do you mean “My Heatpump” app? Is it marked as public? Can you share the URL to it?

Thanks for trying to help, sorry for the slow response.

Now found the video and followed the steps, follow them and can see my system fine but when I log into HeatpumpMonitor.org from the header

If you’re monitoring a heat pump with OpenEnergyMonitor login to add your system

I end up on the home page.

Where am I going wrong?

When you have logged into HeatpumpMonitor, go to My Systems and click on the blue Add new system button:

Thanks, that’s a good help, as I said in my post I had found the video which was very useful.

I have followed it through and can log in etc but when I go from the page you have displayed above to the add new systems page the box which is under the installer URL box where I add my URL is missing, see pic.

Tried logging in on a few different computers with the same result
where am I going wrong?

Ah, that bit may have changed. You’ll be asked to pick one of your systems to add, rather than for a URL.

Ok. Added as suggested and seems to have gone further but cannot see it on the list?

Since the last message saying that has my submission been received.

Has it been approved or do I have further work to do?

Or perhaps it all just takes a while?

Hello @JPB

I can see the system publicly here:
https://heatpumpmonitor.org/?filter=samsung&period=all&minDays=0&add=id&other=1&mid=0

It’s listed under other metering, are you using an SDM120 Modbus electric meter or an original emonPi v1 or Tx3 as selected?

12

I wonder if it would be worth increasing the minimum flow temperature on your system? It’s cycling > 3 cycles an hour, you may be able to increase your COP by increasing that minimum flow temperature 
 counterintuitively

@glyn.hudson and @SarahH may have other suggestions as they have more experience with Samsung than I do

Thanks for your comments.

My mistake on the metering, it is an SDM120, with my ‘black box’ being a EmonHP.

Tried changing the entry, looks like I need to edit it somewhere and save the setting?

Thanks for the comments, we put in the min flow temp as suggested elsewhere and thought it was a decent starting point so all comments welcome.

We can easily add a volumiser or buffer an extra pump which we have in stock but thought it worth trying without as we seem to have a decent flow?

Really pleased to get it working and get some reasonable results especially with the comprehensive metering. Lots of learning!

I’ve changed it for you, all good now!

Yes I would try going a bit higher, it would be interesting to see what flow temperature is required to get it to run nice and steady but there maybe other settings that are worth adjusting that @glyn.hudson and @SarahH will be better able to advise. Are you using the samsung controller or 3rd party controls?

16

Hi @JPB,
I have a Gen 6 so may not be able to help much :face_with_diagonal_mouth:. What controller does the Gen 7 have? If it’s similar to the MIM-E03EN, is there an easy way that you can convey to us what your FSV #2*** settings are (and whether you have a third party roomstat, and if so, is it TPI)?
TBH I run my Water Law much hotter than you (nearer 40degC at the ~15degC ambients we are seeing atm), and I don’t get any cycling faster than ~2-3times per hour.
So it may be just a case of nudging up your LWT FSVs as @TrystanLea wisely suggests, but there are a couple of other possibilities (mainly related to adverse roomstat interaction).

Hi Sarah,

Thanks for your reply. According to some of the utube posts its the same controller, at least in appearance, but my part no does not is very different at DB9204639D from the control or MWR-WW10N from the manual.

We have altered the settings as suggested but when we intially started the HP we soon got a 911 error which is low flow rate. We thought this was air but now we have the level 3 kit working we can see the HP reading is about half the flow of the monitor.

Left it running overnight on heat at 35c and its still going but 7.4l/min on the controller and
17.7l/min on the monitor

Not really sure but think we have a faulty sensor and until we can investigate this further
and get a fix not sure what to do.

Hi Peter,
Can you clarify what you mean by

By “controller” I infer that you mean the Samsung controller (which is what would generate the 911 error), and “monitor” refers to a heat meter that you have added. In which case it does sound like like a faulty (or air locked) Samsung sensor - my Gen 6 creates a 911 error at ~7.0lpm which is very close to your 7.4lpm, and 17.7lpm sounds far more sensible for a 7kW nameplate HP.
You can do a rough check - does your (Samsung indicated) (LWT - RWT) x (lpm/60) x 4180 (if water) give a heat output roughly consistent with your predicted house heat loss (at current ambient temperatures)? If it’s only about half, then your Samsung meter could indeed be faulty.

Hi Sarah,

Yes dead right, Samsung controller, Openenergy as monitor —sorry about it not being very well explained.

We got a 911 a few times after filling and the first few runs but thought it was probably air locked which the Spirovent seemed to successfully snort out. Then we got into it a bit more but it didnt seem to ramp up very hard even when we set the water temps high to make it work but having never seen a Samsung HP in operation thought it was normal. Also it worked on weather law so left it like that. However unknown to us we had left the outside stop temp at the factory setting of 20c so although we had it to stop at 15c in one place it ran in short bursts as it was looking for 20c in another.

Then we got the Open energy monitor working and could finally see what was happening, corrected the temp disparancy, put it on weather law, but it kept failing on a regular basis and everything added up to be probably the flow sensor. Not much to see really on the sensor, wiring is intact and nothing obvious.

The HP is registered, tried contacting Samsung about it other but things got in the way so I will try again soon, looked for a sensor as thought it may be a common part but unable to find much about it, perhaps a newish product.

Left it running on water outlet temp of 35c overnight and didnt fail although seeing 7.4l/min on the controller, will do the same again tonight.

Thanks for the rough check but unable to get a sensible result at the moment.

Impressed with the product, seems decent quality and very quiet. Perhaps I’ve been
unlucky.

Have you seen some of my results on the monitoring pages—look terrible to me!

Peter
