Right definition file for Daikin Rotex HPSU Compact 508 H/C BIV

[DanieleNeo]

Hi,

I searched around and found this old thread where it says the correct file is ALTHERMA(HPSU6_ULTRA).h
#45

I looked at the wiki and found the same thing
https://github.com/raomin/ESPAltherma/wiki/Choosing-the-right-definition-file

The problem is that this file doesn't exist anymore (probably it has been replaced) and I have no idea what is the most correct definition for my machine. I am currently using default.h and it works, but I am missing some values ​​to calculate the COP correctly, can someone help me?

Thanks,
D.

I have a 2011 Rotex HPSU 508 Compact. I use the PROTOCOL_S_ROTEX.h file with some modifications. Essentially it only spits out these values: (my interpretation in german added as comments)

{0x53, 0, 200, 1, -1, "Circulation pump"}, //Rotex Zirkulationspumpe
{0x53, 3, 200, 1, -1, "External heater?"}, //Solarunterstützung

{0x56, 0, 103, 2, -1, "????"}, // Warmwasser Zieltemperatur

Maybe we can identify more values :)

Hi @philipgo,

I tried the definition you said but I think that it's not good for me, some values are surely wrong, operation mode for example is "heating" when my heat pump is off because I'm waiting for the first start (scheduled at 5/12, I bought the heat pump a few years ago and only this year I managed to put it into operation). Mine is 2014 version, so something is different I think. From what I understand Daikin Rotex HPSU Compact is "the same" as Altherma ECH2O (the first versions at least), I used the file def/Altherma(ERGA E EHSH-X P30-50 E_EF series 04-08kW-ECH2O).h and some values ​​come back to me

I'll do some tuning in the next few days...
