"Write failed" during "boiler flowtemp" command #259

Closed arturasi closed 4 years ago

arturasi commented 4 years ago

Hi there, I always get "write failed" message in log when I try to change flow temperature:

Setting boiler flow temperature to 40 C (17:19:40) Sending write of type 0x1A to 0x09, telegram: 8B 09 1A 00 28 (CRC=70) (17:19:40) Sending validate of type 0x1A to 0x09, telegram: 8B 89 1A 00 01 (CRC=3D) -> Write failed.

Despite of this error, inside "info" output I see that flow temp is changed ("Selected flow temperature" field):

But after few minutes this field changes back to value set on boiler itself ("Heating temperature setting on the boiler") value:

Could anybody explain such strange behaviour?

glitter-ball commented 4 years ago

How does your system work? Is it weather compensated (usually have outdoor sensor)? If so, the thermostat will periodically re-calculate the appropriate boiler flow temperature based on the heating curve, outside temperature and, possibly, room temperature.

So, although you've set the flow temperature to 40ºC, the thermostat's calculation cycle will eventually run and produce a new target flow temperature.

What happens if you change the 47ºC setting on the boiler? Does it change there too?

arturasi commented 4 years ago

My system is a standalone boiler Junkers CerapurSmart ZWB series (with built-in water heater), no thermostats/external temperature sensor etc connected, just a boiler with simplest manual flow temperature regulators (one for water another for heating), that's it.

If I manually change heating temperature on the boiler - I see same temperature in "info" in "Heating temperature setting on the boiler" field, so information from the boiler is read out ok.

proddy commented 4 years ago

I think the problem is in the validate process. In the early days I wasn't confident the writes were working so built a 3-stage workflow to write first, wait and then read, and finally validate. Validate compares the values and if it would fail it would retry 2 more times. In the flowtemp function after the value is set I issue a read command to the same telegram type 0x1A to pull back the new flowtemp and compare the values. Perhaps I'm reading the wrong value. You can see it in your log

(17:19:40) Sending write of type 0x1A to 0x09, telegram: 8B 09 1A 00 28 (CRC=70)
(17:19:40) Sending validate of type 0x1A to 0x09, telegram: 8B 89 1A 00 01 (CRC=3D)
-> Write failed. Compared set value 0x28 with received value of 0x34
-> Write didn't work, retrying (1/2)...

Could you get more details of what to compare with log v.

Hm I don't see reading type 0x1A in the log, here is what I have:

and boiler read 1a also comes back with nothing?

I've disabled the validate in 1.9.5b3

arturasi commented 4 years ago

Ok, on 1.9.5b4 I see no validation after "boiler flowtemp".

However, same error ("validation failed") occurs after "boiler wwtemp" command:

Setting boiler warm water temperature to 60 C (17:40:25) Sending write of type 0x33 to 0x09, telegram: 8B 09 33 02 3C (CRC=C4) (17:40:25) Sending validate of type 0x33 to 0x09, telegram: 8B 89 33 02 01 (CRC=9D) -> Write failed. Compared set value 0x3C with received value of 0x32

"boiler read 33" returns this:

Requesting type UBAParameterWW(0x33) from dest 0x09 (17:40:39) Sending read of type 0x33 to 0x09, telegram: 8B 89 33 00 20 (CRC=B8) (17:40:39) Controller -> Me, type 0x33, telegram: 89 0B 33 00 08 FF 32 00 00 00 00 02 4B 00 FF FF (CRC=15) #data=12

so it seems that value is left unchanged (0x32).

I think such behaviour (boiler settings cannot be changed) is because in my system there is no thermostat connected. Embedded boiler controller see that and therefore does not allow to change the settings.

Also I've noticed that "boiler flowtemp" can be changed only to value below "Heating temperature setting on the boiler", and new flowtemp is working for few minutes only, after that it is goes back to the value set on boiler panel (=Heating temperature setting on the boiler).

I will create a new issue about how to change boiler settings without thermostat connected #271
