It is also about a LAD 9 there. You will definitely find some helpful tips. And then open your own thread.
What do you mean by high spread, so before the incident?
- 5-8K during heating operation - 0.2 - 2K in standby Still 4 degrees until the hysteresis of 2K is undercut. I think it will only switch on again shortly before midnight. Spread currently at 0.1
hoihoi together, I have read everything and am a bit confused... We have a Novelan LAD9 system with photovoltaics and only one meter. There are not many devices running. - Controlled residential ventilation - Bus system - usual consumers like refrigerator etc. I noted the value from yesterday and looked at the meter today. I came to a total consumption of about 30 kWh / day. Electricity I wonder if our device might be set incorrectly...? We have the same menu on the device as
We basically have a similar model. I just evaluated from mid-December until now. We also needed 28 kWh / day for heating ELECTRICITY. In fact, this results in a COP of 3.3 from the heat pump meter. That is not really satisfactory, especially since recently the bathroom only gets up to 21.5 degrees, no matter what I set. I have the feeling the system is not running properly yet :(
