Flow temp increase for warm water missing #740

Closed swa72 closed 3 years ago

swa72 commented 3 years ago

I noticed that my RC300/GB192i provides a parameter to increase the set flow temp by xK (5...40) for warm water. However the EMS-ESP does not show this parameter? I could create a log of telegrams (how?), fiddle around with the parameter and post the logs.

German text of the parameter ... "Überhöhung der vom Wärmeerzeuger angeforderten Vorlauftemperatur zur Aufhei- zung des Warmwasserspeichers. Die Grundeinstellung hängt vom installierten Wärmeerzeuger ab."

If you change a parameter on the RC300 the new value is published to all or send to the device resposible for that value. Open telnet (with logging to file) and type watch 10 to see all telegrams from/to the thermostat. Then change the parameter to different values on the thermostat. Search the log for something like "Thermostat->all (id xx), data yy, offset zz" for a thermostat setting or "Thermostat->Boiler..." for a boiler setting, where the data matches your changes.

Ok, I could not set up putty to record anything. Anyway, I've changed the value from 20 to 19 to 21 to 20. Hope that helps.

Ok, now we know what offset 5 in 0x33 is. I'll add it to v3. For mixed heatingcircuits there is a similar parameter, named FlowTempOffset, i will add this as wWFlowTempOffset for reading and writing.

Logging in Putty is simple: Putty_logging

Thanks, here is another one. My boiler has different settings to limit the power.

sensor.boiler_burner_selected_max_power (in HA speak) set by the system depending on use case sensor.boiler_burner_max_power (in HA speak) set by user (not relevant for warm water); aka "MAX.HEIZLEISTUNG"

??? set by user to limit power for use case warm water; aka "MAX.WW-LEISTUNG" I could not see/set this (maybe due to my system)

??? set by user to limit power overall; aka "Obergrenze Maximal Heizleistung" I could not see/set this and changed the setting from 89 to 88 to 90.

Telegram 0x26 is first seen now. Can you do a read 9 26 to fetch the complete telegram. (This telegram is unknown to my boiler.)

read 8 ...

@swa72 Thanks for the telegram. I've added the offset 7 as wwMaxPower (i have no idea for the other values in that telegram). Please try the esp32_dev and check the values and set commands for wwFlowTempOffset and wwMaxPower.

@swa72 can we close this?
