New Bosch HP only recognizes CR10/CR11, CR10H/CR11H, CR20RF, RT800 as remote thermostats

[christic73]

I have a new Bosch heat pump (compress 6800i AW) with a UI800 user interface. I also got a RT800 remote interface on top, which is currently not connected.
This HP apparently only accepts CR10/CR11, CR10H/CR11H, CR20RF, RT800 as remote thermostats. However I only can select RC100, RC100H, RC120RF or RC220 in EMS-ESP.

If I select RC100H in EMS-ESP and send remotetemp and remotehum periodically via scheduler, then the HP shows CR10H as remote thermostat, together with an error code 3111 (wrong remote configuration).

Is there anything I can do to solve the issue? Do you want me to share some logs of the RT800?

Thanks for looking into this :-)

I added a log of RT800 remote thermostat. Maybe this is of interest

Yes, this helps much. Could you please also upload the support info.

From the log i can see that:

• control is set to 6, so ems-esp shows RC220, we can change this text to RT800.
• version of RT800 is v21.03 with no subversion and profduct-id 03
• temperature telegram is longer than known. Two bytes at the end read 01 09. Don't know what this is, but we can trywith fixed numbers.
• humidity telegram is as know from RC100H with humidity and dewpoint.

I'll prepare a RT800 emulation to test...Takes a bit...

BTW: You have a connect module 0x50, What is this for? We have seen such modules as RF base for RF-sensors and RF-thermostats, but no logs for this.

There is a module, which is inserted into the HP. On the manual not is called "K 30 RF". It delivers a "Gateway Module" (0x48) and a "Connect Module" (0x50)

I'm sorry, I'm new here... Could you tell me what do you mean with "support info"?

thanks for the version!

• I successfully selected in "RT800" in EMS-ESP
• I successfully set a Temperature and Humidity value in EMS-ESP
• In the Bosch-HP User Interface I could see, that "RT800" has been set
• In the Bosch-HP User Interface I could see, that set temp and hum has been accepted from virtual thermostat
• The Bosch-HP didn't trough any error message (so far)

many thanks! you are awesome!!
