You’re welcome. Yes, when a TRVZB valve opens according to the schedule you’ve set for it, the boiler also turns on. The setup is a bit complicated, but It’s working perfectly for me now. When setting the schedules for the TRVZBs, you can set up one day and copy the schedule to other days and copy the entire schedule to your other TRVZBs, then alter them as necessary.

Hi, I’d like to give you some initial feedback on what I’m trying.
I find the Central Heating System a really interesting idea that “seems” to work well (mine seems to be due to various issues that have cropped up in the NSPANEL firmware).
I’ll tell you what I didn’t like and what I think could be improved:
1 - the configuration isn’t at all intuitive; if I hadn’t gotten some tips from other forum members, I think I would have gotten stuck;
2 - the need to create a room for each TRVBZ; otherwise, NSPANEL doesn’t understand which valve it’s referring to. For convenience, I had put them all in one room, and now I’ve been forced to create multiple rooms, some of which only contain the TRVBZ;
3 - the need to restart NSPANEL to read the new rooms (I haven’t found any other way to do it). Since it is not possible to share the TRVBZ with other users, it would be convenient to be able to change the TRVBZ programming from NSPANEL, this would allow other family members greater autonomy to customize their own heating choices at home.
Thank you.
Hi, is it possible to reorder the TRVBZ configured in the Central Heating System or do I have to register them again?
Thank you very much for your valuable feedback.
Yes, the configuration is a bit complicated, and even confusing without a manual or proper instructions. We are rushing to release an alpha version so we could get feedbacks as early as possible. We are not experts in this field (thermostat, central heating, HVAC, etc.), and we get a lot of help from our dear users in this topic.
We’ll continue to polish Central Heating System.
Yes. We thought it’s natural and intuitive to design Central Heating System based on rooms. Rooms are a good method to organise your smart home when you have more and more smart devices.
Oh, we should optimize this.
I’ll talk to SONOFF’s product manager who is in charge of TRVZB to find out why it is not possible to share the TRVBZ with other users.
Oh, let me check it with my colleague and see how we could make it happen ASAP.

Hi, thanks!!! I’ve always believed that engaging with users is the best way to improve a device or a new firmware version. This solution truly has huge potential, and I hope it will be further implemented. If you’d like, I’m available for any further testing.
Upon rebooting my NSPanel, all the TRVZBs switched into boost mode, however they didn’t trigger the actuator. Manually cancelling boost mode returned the situation to normal.
Got it. We’ll check with SONOFF staff to verify how the Boost mode is designed.
By the way, rebooting NSPanel Pro should not turn TRVZB into Boost mode. If this was not the case, please submit a log on your NSPanel Pro device through Top drop-down menu -> Settings -> About -> Feedback -> Submit.
Hello. My NSPanel just rebooted after the new firmware update, and a couple of the TRVZBs went into boost mode again without triggering the actuator. I’ve submitted a log.
Last night, v4.3.0 brought HELL to my place… 
Thank God we have ACs - otherwise it would’ve been HELL and an ICE AGE at the same time.. 
Both of my TRVZBs didn’t just become unresponsive - they literally went BERSERK! Random (at least to me) heating/keeping/boost actions, ignoring temperatures and schedules, etc. Restarting the NSPanel and/or the TRVZBs produced completely random results.
Right now I only have time to drop a few screenshots; I can go into more detail later this evening. I also submitted multiple feedback reports during the night - my Device ID is visible in the last screenshot.
Wrong temperatures
Not heating when it should
Not responding both from NSPanel and eWeLink
Random boosting and ignoring schedules
Multiple connects/disconnects/changes
An air purifier (which I don’t have in NSPanel and eWeLink!!) randomly showing as Thermostat
My Device ID
P.S. I have a strong feeling this might be related to - or at least amplified by - enabling/disabling MQTT, which I don’t use and don’t plan to use. I rely on SonoffLAN and will continue to do so, especially after tonight.
I enabled MQTT only for testing, and every time I toggled it on or off, devices and settings seemed to change randomly.
Sorry for the issue. We’ll check the log ASAP.

UPDATE: None of my 15 Zigbee devices work.. 
They all show up as online and connected but none of them update or report data. After a restart of the NSPanel they work for couple of hours, then just stop. I was focused on the valves and the temperature sensors (because of the last two turned-out-to-be-chilly nights) but it’s the same with motion, presence, door, and button sensors. I don’t seem to have any problems with the rest 20 Wi-Fi and eWeLink Remote devices.
Also, everytime I restart the NSPanel I receive these notifications, and one of the TRVZBs goes to boost mode (ID below), the other doesn’t.
Again, I’ve submitted multiple feedback reports before and after restarts and when noticed any of the issues above.
@MichaelLearnsToCode @JoJo I really hope you’re looking into this. I’m not a technical professional but tech savy enough to do more extensive tests if instructed. I can also prepare a list of all Device IDs if needed. As a last resort, I’m planning to do a hard reset in the weekend.
P.S. Tried to turn on Turbo mode, solved nothing, and resets back to off after a restart.
Thank you for your feedback. We have identified the root cause of the issue and have fixed it in the latest version (I will notify you once it is released).

The temperature displayed in the app might be data from a few minutes ago. This is because while the device shows real-time temperature, the app’s temperature display relies on data reported by the device (the reporting interval and thresholds can be configured on the device settings page—please check this configuration).
From this screenshot, the current status shows it is heating.
This device is currently not supported, so its display may be inaccurate after being added. We plan to integrate air quality sensors in version 4.4.0. Could you provide the specific model of your device?
Please, look at the screenshots - there’re huge gaps of hours with no reports from the devices. Even worse, the app reports them as online and connected and displays wrong/old data. Even worse, this wrong/old data is reported (I would think so) to the TRVZBs and they don’t trigger when you would expect - e.g. when the temperatures drop during the night and it has the data from 4-5 hours ago - literally my case last two nights.
The app shows it’s heating but as you can see in the photo the actual valve is closed - thus not heating.
Again, I don’t have any purifier in my NSPanel/eWeLink setup.. 
The thermostat screen showed up automatically on my NSPanel (which is great) - I don’t have it configured in the app. I have the two TRVZBs but then I have this purifier - and I have no idea which device and why the NSPanel thinks this is.
It affects all my Zigbee devices, not just TRVZB. I only noticed it there while trying to understand why they were misbehaving.
..and so on, with not only TRVZBs and SNZB-02Ps, but all my Zigbee devices.
I apologize for the issue you encountered. Thank you for providing the logs. We have identified the cause and are currently working on a solution. A new version addressing this problem is expected to be deployed to your device tomorrow.

This is great, thank you! Looking forward to it.
Hi,
I saw that version 4.3.0 has been released. I’m currently using 4.2.3, which I’m particularly happy with. Central Heating System management works very well. I’d like to know if this new version contains any new features regarding the Central Heating System, and if anyone has tried it, does it seem stable?
Thanks.
If you mean the new central heating system, as far as I know, there is nothing new. I don’t know about the stability, I had people who can thoroughly test this heating, but they still haven’t fixed the issue at iHost.
I would welcome a simple addition to trzvb, because now it’s nuclear physics.
