Question: Explanation for some Values #336

Open NeoCortex97 opened 1 year ago

NeoCortex97 commented 1 year ago

Hi, do you have enough information about some of the parameters?

I was wondering about the DUTY parameter? I thought it might be the duty cycle of either a heater, or a pump, but that seems to be incorrect.

So I would be very grateful if you could share that information with me if you had it.

Could you clarify about what dutty you're talking about?

In Heishamon there is only one pump_dutty, it's work of circulation pump..

MiG-41 commented 1 year ago

Yes , it should be called Max. Dury ( acc manual) , and be in HEX values ,then would be more intuitive...

@MiG-41 we have max duty.. just with pump in front :) and also hex value will not make any sense.. just will be same as in screen :) and i don't understand why Panasonic went in that way... Who is showing value as hex.. which you need to convert to dec to understand it..

NeoCortex97 commented 1 year ago

I will take a look in the docs for the bytes I meant. But something just was strange. On my pump it is above 100 decimal. That is why I was asking about. since if it is a duty cycle, it would not make sense if it was above 100

NeoCortex97 commented 1 year ago

It is top93 aka byte 172. Pump duty.

Also there is a max pump duty, which I did not look up for now, but that is fixed on 130 Dec.

NeoCortex97 commented 1 year ago

To me it seems to be the duty cycle of the water pump. But why does it go over 100. But if it is, shouldn't the decoding hint be hex?

Currently it is Dec + 1

No, duty cycle in electronics is not same duty for pump work :) for pump it's more about pumps efficient point between flow ratio and pressure..

Becouse you are thinking in DEC :) In HEX max value is xFF , with corresponce to DEC 256 , and that is max ( in HP this values are -2 , so 254 in reality ,and lower value is also limited to 64 , otherwise pump could simply not run stable ).... You do SetMaxPumpDuty and this will set max. duty ( same as in menu and TOP95) , and then TOP73 (so real vaue of the pump ) will not exceed that value ( during normal work , in defrost is not valid).

NeoCortex97 commented 1 year ago

That makes sense to me. Since you guys are way more into that topic, do you know of a good introduction to the operating parameters of a heatpump? I want to learn, but don't know how to start - as many others newly getting a HP would likely do.

Even if it is not useful to you pros, could you either compile explanations of the parameters, or link a good explanation for these who are techsavy and want to learn. If you would point me to literature, I would be willing to write explanations and issue a PR for you.

I am an IT-guy and act as a smart home integrator for most of my friends, so I need to turn this partly freestanding numbers into graphs with units and alerting rules.

But thank you all for your help!

geduxas commented 1 year ago

Try to start reading service manual.. i think there is all you need to know and understand :)

NeoCortex97 commented 1 year ago

Thanks. I'll find myself a service manual, but would you like me to write explanations as a pr? I could offer them in German an English. Sadly my Dutch is not that great.

MiG-41 commented 1 year ago

Any PR are welcome , @Egyras is an owner ,and accepting them.
