Junkers FW200 wrong heating circuit mode reported

[FredericMa]

Bug description
Heating circuit mode and modetype of Junkers FW200 are reported incorrectly.

Steps to reproduce
The problem showed up after upgrading from 2.1.0 ESP8266 to 3.0.0 ESP32.

Expected behavior
The example provided in the screenshots show the toggling from manual-nofrost to manual-heat for HC2.
EMS-ESP however shows auto-eco while it should be manual-nofrost. I changed to heating mode to manual-heat and EMS-ESP only shows auto. It looks like the modetype has an invalid state and is not shown in the console anymore. It is also not reported in MQTT.

Screenshots
Should be MANUAL-NOFROST for HC2 (and actually also HC1):

Should be MANUAL-HEAT for HC2:

Additional context
This issue reminds me of a previous issue reported in a long thread here:
emsesp/EMS-ESP#410 (comment)
I guess it was fixed in this PR:
emsesp/EMS-ESP#417
(or maybe this one):
emsesp/EMS-ESP#419

Hi @FredericMa , so it worked in 2.2.x on the ESP8266 but not on the ESP32 v3?

[FredericMa]

That's correct, I would guess it is related to the software and no to the hardware since all other parameters are reported correctly as before.

I can confirm that the fix of @MichaelDvP fixed the issue. Thanks!
