Ämne: Greenline IVT fungerar inte längre efter strömavbrott, kretskortet blinkar

[Ammarens Bruggenkamp]

Först och främst ber jag om ursäkt för stavningen. Jag är en holländsk användare av IVT greenline pumpen och knappt någon här vet något om denna pump, så jag tänkte få hjälp av mina svenska vänner med hjälp av Google Translate!

Problemet är att pumpen inte längre fungerar efter att ha kopplat bort strömmen tillfälligt. Displayen slutade fungera. Men när väskan öppnades hittades en lampa på kretskortet knackande och blinkande. Jag såg i ett tidigare inlägg att detta kan vara problemet. Jag har beställt ett nytt kretskort. Installerade detta igår. Kretskortslampan blinkade/tickade ett ögonblick men tändes sedan med fast sken. Och till min glädje lyste displayen upp! Men själva pumpen visade sig inte fungera: inget varmvatten och värme. Jag stängde sedan av popmp, kopplade ur den, kopplade in den och slog på den igen. Tyvärr hamnade vi på originalproblemet igen: displayen fungerar inte, lampan på kretskortet blinkar/tickar.

Jag är vid vettet, speciellt för att jag och min familj har varit i kylan i en vecka och teknikerna här är knappt tillgängliga och inte vet något om den här modellen. Är det någon som har en idé om vad detta kan vara? Kan det vara så att jag köpte fel kretskort? den jag beställde och installerade om var från Bosch nr 8733702947. Jag ser dock att det även finns ett annat nr 87183113860. Kan jag ha installerat och beställt fel? eller är det något annat som kan orsaka en kortslutning i enheten, vilket gör att kretskortet inte längre fungerar? Jag vill inte lägga ut några hundra euro igen för ytterligare ett kretskort och vänta dagar i kylan innan delen kommer, om lösningen ligger någon annanstans.

Stort tack på förhand för hjälpen och tipsen, hälsningar från ett kallt Nederländerna!

Hi, Google Translate works pretty well but you can use English if you want. Exactly, what type model of IVT are we talking about here?

[Ammarens Bruggenkamp]

great :-) it's the IVT greenline HE C7

Hi!
Yuo can probably buy and change card after card and see what's works but it can be more costly than contact service.
They will probably do the same, but they change back the ones that work and only sell you the one that fail + charge for troubleshooting.

If you want to troubleshoot yourself, buy the kit: 8738209794.

thanks so much for your feedback. unfortunately, the IVT pump is rare in the netherlands, so there are no mechanics with any expertise let alone spart parts... So that's why I'm trying myself. will order some more parts to see if it works... if there is any IVT mechanic planning a nice Christmas holiday to the Netherlands and want to stay in a nice house in the center of The Hague, they can reach out to me for a free stay (in an unheated house in return for fixing the pump, hahahaha :-)

[Carl N]

Ok, it is quite impossible to tell what card is broken, so you need that kit with all cards.
Change them all.

Maybe you can ask for 2nd hand spareparts here

dear all,

Thanks so much for all the feedback and ! I received the other piece, installed it and the pump went on again! The main panel/screen is working which wasn't the case before, so I was very happy. Until I found out that the pump is not actually heating up any water so basically not providing any heat or hot water... The screen appears normal, there is no error code....Any suggestions where to look now?

All feedback and suggestions are welcome!

Thanks,

Ammarens

This is a configuration setup, here is the manual.
https://cdn.jseducation.se/files/pages/install_he_6720643409_01.pdf

To enter the setup menu you need to enter an access code that is todays date (that is showed on the display) today is 1207. (side 48)
Then navigate to menu Hot Water and acknowlidge the Hot water sensor T3. (Side 50)

Then follow the setup guide in page 56 and forward.

Be careful when navigating in service mode so you don't change anything that should not be changed.
Factory setting can be a good value if you don't know what value to use.

Dear carl,

Thank you so much for responding, you don't know how grateful I am that you are helping me and my family out in this cold with your valuable advice! I managed to get into the installer mode. i also went to the menu Hot Water and acknowledge the Hot water sensor T3. (it was already on yes, but i confirmed it). I went through the steps of the manual, but i see most of it is already in factory setting which i dont necessarily need to change. Are there any specific things that i need to adjust to make it finally work and get the machine out of the configuration set up and start working? 

Regards ammarens

You need to set the kurve, the low value (at 20 deg) is usually around 20 and the high value (at -35 deg) you can set to 65.
Then I'm not sure, I have never set up an IVT HE heat pump...

Can you check up what detailed information you have on the T1 transmitter?
Both flow temperature and the set point for this?

[Ammarens Bruggenkamp]

hello carl,

Thanks again for the advice! unfortunately we seem to be a step back... i have again looked at the two cards, to see if the wires were rightly connected as it still didnt turn on and the light on the BAS circuit board was blinking. I detached the connector cables from the BAs/circuit board. after i turned the fuse of the Circuit boards back on, it started an error code: high flow temperature E11. T1.
Did I cause another problem or is it finally showing what the real issue is?

greeting from a cold netherlands!

Ammarens

[Carl N]

Maybe we have an issue with the T1 sensor.
You have to look in the manual side 43 to locate T1.
Then you need a multimeter to measure the resistance over T1 (detached).
I think the attached table show the resistance at different temperatures.

[Ammarens Bruggenkamp]

Hello all,

We managed to fix it! seems that the problem was still with the BAS circuit board. There is a dial with numbers which we turned to nr 7 as that was in the manual. This resulted in the error. Then we found out that on the old circuit board, the dial was turned to 6. And we did this with the new one, the machine turned on!

Thanks all, especially Carl, for thinking along!!
