EMS-ESP32 Unable to change any values on Junkers FW200

ESP-32 Running latest firmware (v3.2.1)

Bug description My Junkers FW200 controller displays all information correctly, but changing any values has no effect. Connection Status shows Tx Errors with ~20% TX success rate. Console also shows TX errors (see attached screenshot).

Tried changing all available TX protocols in settings without any success. Also tried changing flow, heating and other values for boiler device - same TX errors.

Steps to reproduce Open web console dashboard. Select FW200 thermostat, change temperature or date.

Expected behavior Temperature or date changes

are you able to change boiler settings? did it work in previous firmware versions or is this the first time you tried it? also which hardware are you using and how is it connected to the EMS lines.

Sep 04 '21 14:09 proddy

I'm using EMS Gateway S32-LR connected to the BUS interface in the distribution box:

20210904_190420

The Distribution box is about a meter away from the gas heater with integrated FW200 thermostat.

At first I tried using the firmware that came originally with the device (think it was v3.0.x), but that version did not even have an option to edit any values in the dashboard. I've updated it to the latest earlier today.

Unfortunately no luck with boiler settings either, I can read them but changes are not applied and errors are thrown in the console.

Ok, thanks for sharing. We'll come back to you with some next steps to debug

Sep 04 '21 18:09 proddy

Can you try and move the Gateway to the orange BUS terminal? Your TX is very low. Maybe that will help.

Sep 04 '21 19:09 bbqkees

Thanks for a suggestion, but after switching to orange BUS terminal the issue persists - I can read the values, but not change them.

Correct me if I'm wrong, but from the following logs it seems that some TX commands are successful (I'm assuming they are value read requests), while manual TX commands always fail.

Could it be the protocol issue? I'm mostly testing with HT3, but also tried changing to EMS or EMS+, without any observable differences.

Sep 05 '21 07:09 simasjoris

Yes it looks like some of the Tx is getting through. What you could try is going into the console, then su and log all and typing call thermostat temp 18 a few times to see the success rate.

Sep 05 '21 09:09 proddy

I've tried sending the call thermostat temp 18 command 5 times. Here are the logs from the console:

I can't see any other error messages except for the usual Last Tx Read operation failed after 3 retries. Ignoring request: 8B 90 FF 00 20 00 6F ones. Does that mean that the temperature set commands are actually sent to the device?

Sep 05 '21 11:09 simasjoris

yes, looks like it works most of the times. Is the thermostat actually set to 18? You can check with the show command

Sep 05 '21 11:09 proddy

No, unfortunately it is still stuck at 22:

It's strange that the value is not being set. I see

the value 0x24 (which is 18 * 2) is sent and validated.

@MichaelDvP any idea what could be happening?

Sep 05 '21 12:09 proddy

I also have junkers FB 10 remote thermostat that was used originally to control the temperature remotely. I wanted to try setting values for it as an alternative, but it doesn't seem to be detected in the device list:

Unknown: Junkers unknown (DeviceID:0x18 ProductID:109, Version:16.01)

It looks just like the FR 10 thermostat, which is in the supported devices list. Perhaps it would be possible to reuse the same commands for FB 10 as a workaround?

Sep 05 '21 12:09 simasjoris

I actually managed to change a setting! Boiler has properties maintenance scheduled and maintenance set time which do persist after changing. They are the only changeable settings though - all other setting change back to original values.

Sep 05 '21 12:09 simasjoris

the value 0x24 (which is 18 * 2) is sent and validated.

Sent: yes, validated: no, the validation is sent out, but the reply is missing. Looks like the thermostat is not responding to the monitor telegrams, 0x16F, 0x170, etc.

@simasjoris Please do on terminal the commands read 10 16F, read 10 170, also check settings with read 10 165 and also the monitor from the remote thermostat read 18 16F.

Maybe junkers remote thermostats act in a different way and values are not monitored by master. Or the thermostat uses different monitor telegrams, then we need a longer (some minutes) log, mybe with watch 10 in terminal. Some telegrams from the remote thermostat (watch 18) could also help.

@proddy The remote thermostat should be added to device-lib after the actual pr is merged. First we also need to test which commands it responses to. @simasjoris Please post also he reply to read 18 179 (older telegram-type) and read 18 165 (newer telegram-type).

Sep 05 '21 13:09 MichaelDvP

@proddy and @MichaelDvP, I appreciate your effort to help me out! It's truly interesting to delve into the secret communications of the heating system in my house :)

I've tried the read commands, but it looks like there was no output. I've also tried them after enabling watch 10 and watch 18 - here's the full log:

That's strange, the telegrams are right, the thermostat publishes the monitors for hc1 and 2:

000+05:25:58.526 N 36: [emsesp] Thermostat(0x10) -> All(0x00), JunkersMonitor(0x16F), data: 03 02 00 DC 01 48 00 D0 0A

The remote thermostat only sends the actual roomtemperature in telegram 123 (and have no telegrams 0x16F, ff.):

000+05:25:41.207 N 21: [emsesp] Unknown(0x18) -> Thermostat(0x10), ?(0x123), data: 00 D0

The roomtemp is republished in pos 6 of thermostat 0x16F in an extra field. We need some logic to take this as room-temperature, but the value 0xF334 for hc without remote-thermostat seems strange (-327.6°C).

But the thermostat does not reply to any request from emsesp. It's not a physical issue, telegrams are sent out and repeated by the master, but the thermostat ignore them. I have no clue why. A shot in the dark: Try to change the emsesp-address to 0x0D (modem), maybe your thermostat doesn't like the service-key.

Sep 06 '21 06:09 MichaelDvP

Changing to 0x0D (modem) did not have any observable effect, but after double-checking the boiler properties I've managed to find two more values that I can change - selected flow temperature and ww circulation pump frequency. I must have missed them somehow as it takes a couple of refreshes for the values to appear.

It looks to me that thermostat properties hc1/hc2 current room temperature are most likely mislabeled. I think they actually refer to heated water temperature for perimeters 1 and 2, as their values 30.4 are similar to boiler's current flow temperature

Ideally I would like to be able to control the hot water temperature in the system so that I can map it with a remote temperature sensor via home assistant. I'm hoping I can achieve that with the previously mentioned selected flow temperature in the boiler, but perhaps FB 10 thermostat will have some other properties that I could tweak?

I'll be eagerly waiting for EMS-ESP updates to support it! Please let me know if I can help in any way.

Sep 06 '21 09:09 simasjoris

as mentioned the current room temperature is taken from the thermostat 0x16F, 0x170 pos 4, which is 32.8°C (0x148) for both hc. With the remote FB10 we have to take pos6, but without reading the settings telegram that is not possible.

In the full log from here the thermostat sems to me very quiet. I think there is something wrong in configuration.

I don't understand the system, there are hc1 and hc2, hc1 have a remote roomcontroller FB10, hc2 not, On IPM channel 1 (hc1) there is nothing connected at all, hc2 is mixed, but have no remote. Why there is a IPM2 if channel 1 is not used?

Without the possibility to read the settings via emsesp, you have to check and note all expert-settings in the FW200 and post it. Also the hydraulic plan would be helpfull.

Sep 06 '21 10:09 MichaelDvP

Hm, i guess the FW200 is builtin in the boiler (high value of internal sensor) and in factory state. It is configured as dumb configuration panel for the boiler and does not control any heatingcircuit. This fits to:

it does not send boilertemp to the boiler
it does not send pump/temperature commands to mixer. both is needed to control a circuit. And therefore we can't set/query any value from thermostat.

Sep 06 '21 12:09 MichaelDvP

FW200 is builtin in the boiler (high value of internal sensor)

@MichaelDvP Yes, that is most likely the case. So in order to control the heating in the house I should change the boiler values, right? Other option would be to control the target temperature for FP10 remotely, triggering the heater to turn on or off.

Here's the plan of the heating system: Heating system plan

As for the expert-settings, do you mean the settings available in FW200 console after entering the service menu?

Sep 06 '21 13:09 simasjoris

The ipm2 is missing in the plan. hc2 is a mixed circuit and pump/mixinvalve is connected to ipm2-hc2. Where is the pump for hc1 connected, is it builtin the boiler? Is hot water managed by charge pump or 3-way-valve?

I only find german junkers-manuals for FW200, The hc configuration is here, page 45, 8.1.1. Systemconfiguration: press menu button for > 3 seconds.

Sep 06 '21 14:09 MichaelDvP

Pump 1 and 2 are separate from the boiler, here are the pics: 20210906_195919 20210906_195915 20210906_195219 20210906_195248

Sep 06 '21 17:09 simasjoris

Look ok for me, but i don't understand how hc1 IPM works without pump connected to IPM-P1. I also don't understand why the FW200 does not send any command to the devices and do not answer to requests. Sorry, but i give up, i have no further ideas what to test. @proddy Do you have other ideas or do you know someone with a FW200, who can cross-check settings.

Sep 07 '21 07:09 MichaelDvP

Perhaps HC1 is just the whole water circuit connected to the boiler (using the boiler pump) and HC2 is switched in and out the water circuit with the 3-way valve.

Sep 07 '21 07:09 bbqkees

I also thought of that, but hc1 is configured as "unmixed, with IPM" and for this the connection should be like this.

Sep 07 '21 07:09 MichaelDvP

The Wilo pump in the pictures is for drinking water only, it seems to be in the boiler circuit? So maybe we are assuming the installer did a good job instead of just messing around?

Over here everything seems to work fine. I changed the mode from nofrost to heat via the web UI. A few seconds later, I see the change being received via MQTT in home assistant. Afterwards, the heater fires up, the pump of the heating circuit is activated and all goes as planned. Changing the mode back to nofrost afterwards also works as expected; everything is turned off again. Also changing the heating circuit selected temperature works without issues.

If there is anything else I can test to help, let me know.

Sep 07 '21 20:09 FredericMa

Perhaps HC1 is just the whole water circuit connected to the boiler (using the boiler pump) and 
HC2 is switched in and out the water circuit with the 3-way valve.

If I had to guess, Willo pump is the circulator for warm water, while HC1 and HC2 are two heating circuits actuated by the same Grundfos pump and Herz 3-way valve to switch between them.

@FredericMa , does your FW 200 have the physical switch to select between modes? If so, does web UI override the hardware setting? 20210906_163957

I'll test a bit more to see if I can control the heating of the house with selected flow temperature for the boiler - setting it to a temp higher than current turns on the heater, but a question remains if that triggers the heating pump as well.

Sep 08 '21 07:09 simasjoris

does your FW 200 have the physical switch to select between modes? If so, does web UI override the hardware setting?

@simasjoris Yes, my thermostat has exactly the same switch. EMS-ESP overrides the hardware settings. As you can see below, the switch is on auto while the display shows 'vorst' (=nofrost). The language is set to Dutch. Also, from the moment EMS-ESP controls the system, 'netcom actief' (=netcom active) appears as well as the NC icon on the bottom right.

My thermostat is mounted to the wall in our living room and is not integrated in the heater. Did you try to connect the thermostat to the bus instead using it integrated in the heater to check if that makes any difference?

20210908_220136

Sep 08 '21 20:09 FredericMa

I'll support you with my little acknowledge. @simasjoris please check the display on your FW200 showing that icon: 'NC' as it is visible at @FredericMa picture. If this is not displayed than the reason for that faulty handling and not answered requests could be the 'FD-number', in German: 'FertigungsDatum'. @simasjoris your FW200 has 'FD790' -->> October 2007 and your gas-heater ZSBR28 'FD887' -->> Juli 2008. So the including software is a bit old for handling requests coming from external 'modems' like ESM-ESP, or MBLan2 etc. But anyway, receiving and decoding data from your heater-system is possible without data-requests. Attached you'll find two pictures for that FD-number handling and also that minimal required FD-number for controlling the heater-sytsem, mainly that 'thermostat'.

FD-number list: Junkers_Fertigungsdatum_tabelle

Minimal FD-Requirements (FD889 -->> 09/2008): Junkers_FD_MBLan_Regler

That FD-numbers are required for that Fxyz-series of 'thermostats' for controlling the heater-system. They aren't required for receiving and decoding heater-data send by the heater-bustypes 'HT3, HT4i'. For Cxyz thermostats (EMS2) the FD-number is not important, they all an be controlled by modems.

@proddy That list above could be placed in your wiki for Junkers and Fxyz - thermostats
