Ämne: Nibe vvm300 settings

[elena]

Hey! I have a Nibe vvm300 ,  with a fighter 2026 . Floor heating in concrete.  I think i messed up with the settings because the consumption is insane. For example now 18 celsius outside and consuming around 50 kw per day . I tryed different curves and offsets. doesn't change much ... the supply temp is around 23/24. Can someone tell me how I can solve it ? any specific setting which leads to lower consumption or ? Thank you in advance .

Hi! VVM300 is more or less just an electric boiler. You should check if the heatpump Fighter 2026 is working as i it should or if there is a problem(?) If there is an error in F2026 the VVM300 will produce the heat with 100% electricity instead of just one third of it.

Can you tell me the settings in meny 2.0 (both values) and 2.1; 2.2; 2.3.

Hey !sorry for my late reply
2.0 -25.0(24.1)c
2.1 -7
2.2 -0
2.3 -15

[Carl N]

I hope it is not minus 25 in 2.0 ?
The slope in 2.1 should be lower, typically value for underfloor heating is 4.
Change this to 4 and if you start to freeze then adjust it up one step a day.

hey Carl N ! I allready freeze at this curve … should I decrease the curve to 4 and turn the offset higher? ATM with the mentioned curve I have 22.5 Celsius indoors  and around 70 kWh per day 👀Malmo area 14 Celsius outdoors

You don't have any alarm on the pump?
Please check meny 5.2 and 5.3?
You can try with a higher offset, but 0 is a normal value.

Thanks for You’re answer again! 5.2 says normal 5.3 pump heating stoped .I decreased yesterday to 4 curve  and so far the consumption  looks good 27 kw until now! 21 Celsius indoors. Any advice what to do on those settings which  the warm water or  the heat pump starts stops time ? I played around and I think I messed it up👀thank you in advance 🙏🏻🙏🏻🙏🏻🙏🏻

I don't know what setting this is.
But download the manual and reset to factory settings for the ones you are unsure about.
