Termet ECOCONDENS GOLD PLUS + ROUND with Wi-Fi - Open-Therm - connected incorrec

I have Termeta ecocondens Gold Plus 32 Kw. I have a Honeywell Evohome control system with heads on radiators and an OT gate. I do not know how the gate works, but rather the stove tries to keep the temperature around the manual setting, i.e. 55 degrees for me. I only noticed that when it's warm, the temperature goes down to 49, while when all radiators are open, the temperature is equal to the set temperature, i.e. 55, and when the valves on the radiators close and one radiator remains, it increases to about 60 degrees. I do not know if this is how I control this OT bridge, or maybe the boiler controller modulates this way. When all rooms are welded, the controller turns off the stove. Sometimes with one radiator, the boiler is not able to modulate so low and L3 crashes, hysteresis set to 10 degrees, I wonder if I should give it to the max, i.e. 15, burner blockade for 15 minutes. P1 40, P16 2, P17 18, P20 10, P24 15. And with these settings, L3 occurs maybe 2 times a day.
I'm wondering if I should add a weather forecast and set P26 to 3? Will it be like this?

Hello,
I am writing because I was looking for the answer to the possibility of connecting Google Nest as a driver for Termet gold 25k 2f.
I've had it for a week...
Everything works fine.
Now I have to see what's cheaper Google or the curve will turn out in a few days.
Oh, connected with opentherm ....

I'm asking because I don't quite understand. Google Nest works with Termet after OpentTherm?

So connected under the opentherm input.

Hello, I have a teremet ecodens gold plus 32 boiler. I bought a Tech wifiOT controller. I have two temp sensors, one external and one internal. I use the eModul application and I am able to set the HUW temp. The boiler responds correctly, but does not respond to the set room temperature - the boiler does not respond at all, it does not turn on and does not heat up. Tell me what could be the reason?

Hi!

I have an ecocondens plus gold 35KW boiler, which one should I buy, do I need a controller for this furnace?
Apparently, older models (mine is from 2017) do not support it.

I'm looking for something similar to ST 2801, it doesn't have to be connected to WiFi.
So that it can communicate with my stove as best as possible and have a touch screen.

I would like to ask for some suggestions and advice.

When I see how this board is designed, I am discouraged from buying this stove.

So buy a Scottish product, you will have a better plate.

Can I find something better than the ST-292 controller FOR ECOCONDENS Gold Plus (I don't have opentherm)

Any suggestions??

ViSSmann tiles are not better either. Three processors, quartz far from the processor, capacitors too. Only the lengths of the insulation gaps seem to be maintained correctly

The Termet Komfort controller seems interesting. Communication with the boiler, the rest is set in the application on the phone. Room sensor with the ability to create up to 3 heating zones.

For Termet Silver/Gold I can recommend the Czech PT52 which runs on OpenTherm - you set a lot of things on the panel including functions that other OT controllers don't give a shit about i.e. you have a DHW timer heating option, power shown, IN/OUT temperatures and heating curves. It's not overpriced and Salus or some EMOS, Round, etc. don't have as many features. In addition, the PT52 powers completely over the OT data bus, no batteries needed. It's not perfect, the software has a few mini bugs but that's a pimple.
Totally better option than the V293 on/off from the kit or some moronic Salus.

PT52 has a mobile preview?>.

no, I asked aloud if you really need it because in my opinion a superfluous byte. But the Czech manufacturer also has such a model although the price is appropriate then. Realistic needs are behind the cell? It heats and does what it's supposed to do, there you don't mess around - it's not a robot vacuum cleaner, etc. This is my opinion, you set and forget. It's better to forget about Techa and get a comfort module from Termet, because it costs 600zl and can handle more things, even complex hydraulic systems. The downside is that the software is rather written for old versions of Android (there is no iOS) because it looks like it is 10 years old, but in time it may change.

See the manual for how many things it can handle and the price is already reasonable and is tested by them (the manufacturer of this module also makes electronics for Gold). If you must have it Techa I would exclude completely.

I wrote above but didn't quote you sorry, 292 is crap, plain on off in the sense as you don't have OT as you have Gold Plus. PT52 works nice and nothing more is needed, only https://www.termet.com.pl/produkt/modul-komfort/150 you can possibly try but it's a minimum of 600+ these room adjusters probably, if you have a simple PT52 plumbing and nothing more. You can even see the power with which it is going, the temperature and control the DHW in the hourly and weekly schedule.

I have a Comfort module and room controllers. The ability to control from a cell phone is very convenient. Unfortunately, the system works On/Off without modulation and this is a huge drawback, because the boiler shuts down and then goes to max power. An OT modulating controller with a convenient mobile app would be ideal.

there is info that curves with sensor also supports? The boiler itself also has the option of curves bypassing the controller, but through LIN I do not know if it would still work (if LIN does not take control after all). How do you supposedly solve that in room X you want to have heat, underfloor heating and valves? But what are they controlled by some additional module? Boiler of average class and you spend a lot of PLN on such trinkets hmm? Exchanger in my opinion for a few years at most and to be replaced, I would rather add to a better boiler on Al-Si exchanger than some trinkets. I have a large apartment with a cable and more or less it is good everywhere and the underfloor heating system takes a long time to "surprise" to play with the control on demand because it will not work, where I want more heat I gave a larger flow rate.

The five-point weather curve is operated with the ability to change in the application. I have two controllers, the boiler turns off if it reaches the set temp in both zones. As the temp drops by the hysteresis it turns on again.

Hey guys,
I created an account just to confirm that Nest Thermostat gen 3 indeed works with Termet via OpenTherm.

EcoCondens Silver Plus combi. It's currently 15 degrees outside and the thermostat sometimes tries to lower the temperature below 40 degrees so it can maintain 25 inside. Increasing the desired air temperature, the water temp rises as expected.
To anyone searching for OT solution - just go with Nest. They are pretty cheap (second hand) nowadays. I got mine for half the price of a Termet Comfort kit, which I also purchased and just returned, because this thing is basically an on/off controller and is pretty much useless (to me). I also have a Honeywell T6R, which sadly does not work with the boiler via OT for more than 3 minutes. Communication is simply dropped both ways. Nest on the other hand works like a charm.

>>20909867 Does indeed this comfort controller from thermet not support modulation of boiler output?

According to the distributor of the controller, it does. What I found though is that modulation does not depend on the controller. The boiler itself modulates which can basically be done with a simple on/off controller. The comfort module is nothing but a remote which doesn't even have all the functions of the panel itself as the distributor claimed. It can't automatically adjust water temperature based on room temperature. Basically an internet connected on/off thermostat. According to the distributor "You have to manually choose the appropriate water temp so the boiler does not turn off while you are still comfortable". Quoting what I was told on the phone before I pack the useless crap and send it back.
I am super happy with the Nest thermostat. It changes water temperature on the fly based on air temperature. I even set the boiler to floor heating instead of radiators so I can go below 40 degrees at the end of last heating season. I'll see how it goes in the following weeks but I believe the max 55 degrees will be enough. Last season, the first gas bill using Nest was ~125 Eur compared to ~200 the month before (similar weather both months, 25.5 degrees inside...you know...happy wife, happy life...). The difference is more than half the price I paid for the Nest itself.

For Gold and probably Silver I recommend the PT52, it's not expensive. In my opinion it modulates the CO temp according to the curves.
But what is important for me - it shows the outside temperature (unfortunately not permanently but alternately with other data). It also shows the return and supply temperatures.
Most importantly it has a schedule of when and how to heat the DHW tank. New ones I have seen go for 250 each. It is fully powered from the OT line i.e. from the boiler. No batteries are needed.
You can heat the tank to your own temperature on demand. If the boiler throws a service error, you will see this on the PT52 panel. There is no point in approaching the boiler in general.

There are no WiFi or app-type features, as these are unnecessary. It's supposed to heat and I don't change anything remotely.
The Lyric T6 I had, half of those features it didn't have for it's unnecessary app and bits and bobs that make no sense to me. The ideal OT controller probably doesn't exist in a small box like the Salus Quantum should have open source software and then people would make something sensible for themselves. Pt52 has bugs in the Polish translation, some minor bugs too, but there is no need to cry about it as they are unimportant.

Termet Comfort - officially it is an ON/OFF controller, BUT! having a room adjuster, in the application we can set the parameter "zone temperature influence". Then the operation is such that the water temperature results from the five-point heating curve. For example, we set the water temperature to be 35C for an outdoor temperature of 15C. If you set 22C in the room and it is 21.9 then water temp = the temp resulting from the heating curve (35C). But if it is e.g. 20C in the room, then the water temp will be : temp from the curve + correction = e.g. 35C + 8C = 43C. In this way, we obtain a fully modulating control, ensuring on the one hand dynamic reheating and on the other hand striving to work as long as possible on minimum power. This is both comfortable and economical.
In addition, with the tel app, everything can be easily changed. What's more, the comfort module can control 3 independent pumps with 3 independent temperature zones.

Hi. Have you managed to find a compatible opentherm controller/thermostat for the ECOCONDESC GOLD PLUS?
In my case the only difference will be to work with the floor zone control panel.

>>21280727 pt52 but I don't know what this cental is about, I wrote above. It has the most bits and bobs of what I've seen. Reasonable price. I have an underfloor one but apart from the rotameters nothing controls it, no need.

I've gone a bit round the bend, to the edge!
I am looking for a control system for underfloor heating zoned with opentherm. A system that can be integrated into home assistance.
So far I see that the Polish Tech Sinum controllers are suitable for this and it is possible to integrate this with HA. All opinions and advice welcome.

>>21281223 question why you need it, at my place I would add maybe two thermostats from noon to close the petrol, and so the rest works only on rotameters, nothing more is needed and the temperature in the house is pretty much regulated itself, the inertia of the underfloor is huge, there is no point in wasting money on it. Unless you have a lot and even more time to play with. My three cents. I would also recommend these Tech's to check, but as you already know them. I had visions similar to yours, without what HA because I don't need it, after 5 years I still don't have thermostats in the rooms or headers on the manifold. It makes more sense, if the house is too big than it needs to be, then maybe it makes sense.

@gReaT if you want to play , I gave it a go , but if you have a lot of self-denial then:
Read my posts @marek_k in this thread .

@krzys-iek @kmarkot Thanks for your replies. What makes me think of such a more precise control of the central heating? House about 120 m, ground floor anhydrite screed - thinner than mix-krete about 2 cm and less porous, as a result shows less inertia. First floor on a wooden ceiling, underfloor heating in a dry system: milled XPS 25 mm boards, covered with alu foil with 16 mm pipes. With this solution, I don't think I have to worry too much about inertia, as is the case with underfloor heating all over in a traditional cement screed (mixologist), where continuous boiler operation would be most economical.

Very cool thread, I already thought I would find all the answers here.
I have a question a bit from the other side, more about the OpenTherm control. I've probably already dug through the entire internet and the documentation that can be found there.
I have a Termet Gold Ecocondens, this is hooked up to a Tech-a I3 plus OT controller, two pump groups for the circuits and the DHW is hooked up to the furnace.
Generally the system works, it's all fired up on the RT contact of the furnace and weather from the furnace, basically this controller does nothing except control the pumps/valves and that's what I'd like to change.
I've been able to successfully rewire this to OpenTherm, but I'm not sure if it's possible to cover hot water with this. At the moment I'd like to keep the water heating off, but it's impossible to do so completely. When the OT is connected, if the hot water temperature from the Tech is below 35, the furnace overrides it with information (minimum), which probably means that I can't turn this heating off. Another question is whether it is possible to embrace this Legionella function in such a system, I assume that it must be switched on in the furnace.
I'm wondering if anyone has experience of running this controller with a cooker and if it could be embraced after OT and if anyone uses the heating curve just through this controller. Unfortunately the Tech documentation is not very comprehensive in the details I am interested in.
I have tried removing the tanktimer jumper, according to the documentation it should be removed, but it does nothing.

Is the PT52 controller one for the whole house? I have an upstairs and downstairs to heat, for this there are two circuits, a clutch, two pumps, one for each manifold.
Is it somehow possible to connect two with an upstairs and downstairs split?
