THZ / LWZ Tecalor Stiebel Eltron Heizung

I tried to do so, but the command ended within a few seconds and logged  just a few registers:
..
What am I doing wrong?

Hi Willy
Nothing wrong, you have an older version of thz-fhem. I use the sub THZ_debugread (line1241) for debugging and I change it very often. You can select some register manually  or select an intervall, just by uncommenting some lines.
I need to debug Andre´s old firmware.

@ Immi can u add the other lines
0a 033b - flow rate/Volumenstrom, 0.1 l/min
0a 064f - hum. masking time/Feuchte Maskierzeit, min
0a 0650 - hum. threshold value/Feuchte Schwellwert, %
0a 06a4 - output reduction/Leistungsreduktion, %
0a 06a5 - output increase/Leistungserhöhung, %
0a 09d1 - humidity protection/Feuchteschutz, bool
0a 09d2 - set humidity min/Feuchte Soll min, %
0a 09d3 - set humidity max/Feuchte Soll max, %

I cannot just add it, because they are not working for my firmware.
I have to think how to manage it, maybe with an attribute like for Peter.

Hi immi,

thank you for your answer.

I'll check v0.125 tomorrow. In the meantime I tried to debug all registers from 1..FF, but I got only two entries in the logfile:

I changed the debug routine a little bit.

It seems to be timing issue.

@Immi,

i have checked


Added in getsonly
"sFlowrate"                     => {cmd2=>"0A033B", cmd3=>"0A033B",     type =>"1clean", unit =>" cl/min"},

Outpud is Flowrate in Centiliter / min
THZ Display 19,1 Output lik 191 cl/min

i make a interval an test over time.

Während der Messung sollten aber alle Thermostatventile zu sein, so dass nur diejenigen Heizkreise in die Messung einfließen, die direkt angebunden, d.h. ständig offen sind. Sonst stellst Du einen zu geringen Wert ein und es kann passieren, dass in einer unglücklichen Situation der Mindestdurchfluss unterschritten wird.

Ich hab mir den Satz paar mal durchgelesen, verstehe ihn nicht. Wenn nicht geheizt wird sind noch per default alle Heizkreise zu über die Regler? Da ist keine ständig offen. Oder missverstehe ich da was?

[belu]

@ Houseownwer.

Die Anlage braucht einen Mindestdurchfluss von 550 l/h also mehr wie 9 l/m.

Wenn die nicht errei hat werden geht die Heizung am Störung. Wenn alle Heizkreise geschlossen sind hast ja theoretisch 0 durchfluss. Wenn die Heizung trotzdem heizt wegen niedrigen Außentemperaturen kommt dann eine Störung. Um das zu umgehen gibt es 2 Möglichkeiten die ich kenne. Einen Kreis immer offen lassen der als Bypass dient und über den die 9 l /m laufen. Oder eine Hadraulische weiche. Hab die heute Mittag eingestellt. Alle Kreise zu umwälzpumpe laufen lassen und dann auf etwas mehr wie 9 l eingestellt.

Es muss immer gewährleistet sein das durchfluss  da ist. Die anlag ist ja im default 30 / 70 Vorlauf Rücklauf gesteuert. Das heißt die Anlage muss umwälzen damit sie weis wie warm der Boden ist um dann die den hc 1 set Point zu erreichen.

Stimmt soweit. Bei mir wurde das so realisiert, dass es 2 Heizkreise gibt, die immer offen sind. Das sind die Flure in EG und OG. Die haben nur sehr wenige Heizschlangen, heizen deshalb nur wenig mit, aber sorgen eben für einen Mindestdurchfluss, wenn alle anderen Heizkreise zu sind.
Die hydraulisch Weiche gabs zusätzlich - sicherheitshalber. Aber die habe ich komplett zu gedreht. Nachdem ich die Thermostatventile wegrationalisiert hatte sind ja immer alle Heizkreise offen.

[houseowner123]

Danke für die Erklärung willy und belu.
Die Raumthermostate sind immer alle auf max. offen gestellt.
zu den Ventilen im Verteiler: Sind die stromlos dann immer offen? Also nur einen im EG und einen EG von den Ventilen abschrauben? Richtig?

[belu]

@Houseowner,

Ohne Ventil sind die Heizkreise offen. Die Ventile gibt's als NC normaly close oder NO normaly open. Würde es eher abziehen dann bist sicher. In der Regel NC verbaut. Stromlos geschlossen.

Ich hab echt Geld ausgegeben habe in meine sind Stetige Ventile 0-10 V ich muss mal schauen wie ich alles trotzdem hinbekomme das die THZ nicht taktet.
Hatte eigentlich nicht vor immer alle offen zu lassen. Mal schauen was mehr Energie spart. Evt Kompositionen aus beiden wenn die Heizkurve sehr knapp ist.

Wäre echt doof habe überall analoge Sensoren und fuzzy Logic regler für 0-10 v

[willybauss]

Hatte eigentlich nicht vor immer alle offen zu lassen.

Kannst ja nach dem perfekten hydraulischen Abgleich wieder die Ventile in Betrieb nehmen und die Heizkurve um 1 - 2° parallel nach oben verschieben. Dann haben die Ventile eine Regelreserve und das Geld war nicht umsonst. So kann auch Jeder im seinem Zimmer die Temperatur etwas höher stellen, wenn er das möchte.

Hi Andre
you are sending too many commands to the heatpump in a short time.
If you want you can change line 1283
select(undef, undef, undef, 3);
in this way it will wait 3 seconds between each command/register
immi

[andre.k]

Hi immo,

it's better with 3 sec. wait time, but I run still in a timeout.
I don't understand why we got the "02-new unknown answer". I would expect return code 0100 or 1003.

As explanation:

• if the answer is starting with 0100, I parse the message (eg FD where I remove footer and header B6FD01B7)
• if the answer is starting with 0103, the heatpump does not know what to do with the command (e.g. 02 command not known)
• if the answer is starting with 0104, the command is incomplete; the heatpump expects a longer command  (e.g. 0A UNKNOWN REQUEST)
• if the answer is starting with 0102, a CRC error occured in request
• if the answer is starting with something else "new unknown answer"

This week, I have not so much time to support, maybe I have a better idea next week, how to scan your registers.
I think at the moment, you can live quite well with the actual status.



Hi Belu
I just uploaded v0125, tomorrow you can update.
some of your new parameters have been implemented: use the attribute firmware.
changelog

This module is starting to support (read-only experimental mode) older firmware 2.06; the following attribute adapts decoding and blocks any write back to the heatpump 
      attr Mythz firmware 2.06
This module is starting to support newer firmware 5.39; the following attribute adapts decoding
      attr Mythz firmware 5.39
If no attribute firmware is set, it is assumed your firmware is compatible with 4.39 (standard mode for everyone

@ Immi,

i tested the 0.125, works not with my firmware 5.19, the firmware is the same 5.39 only the heatpump is the diffrent.
can u add the line 5.19 or 5.39 for newer firmware?

big thx

please be more precise, I do not understand.
What is not working?
have you set the attribute firmware to 5.39 in your config file < attr Mythz firmware 5.39 >?
what do you get if you type < get Mythz sFlowRate >?

willy and others: the LWZ/THZ is full of surprises. I just noticed that when the HC heating is on, the cooling rate for DWH doubles. No warm water was taken at that time. Can somebody check this behavior on their heap pump too? It is bizarre!
