The Efficient Home Forum

Hello,
After long time trying to figure out solution for my issue, and unable to find anything in the internet last hope is to ask here.

I bought ATC928G3000 with R8810A1018 Module.
I have Boiler Radiant R1K 24/B (Open Therm Supported).

I have connected Opentherm Relay, and synced it with EVOHOME module.
Module seems to be connected if doing RF COMMS CHECK.

System Devices:
BOILER CONTROL: OPENTHERM BRIDGE
ZONE NAME: Living Room
TEMPERATURE SENSOR EVOTOUCH SENSOR

Issue is that after OpenTherm module connection to boiler it seems that Boiler gives all the control to the OpenTherm device.
I cannot even control temperatures of water/floor heating and even switch on/off boiler or switch between water/Floor or water+floor heating.

I have configured Evohome to work as an temperature sensor to act as a single zone Thermostat.

All would be fine, if floor heating would switch on, but it seems that Evohome doesn't send any info to boiler to switch on floor heating and start circulating water.
If I click Opentherm module button, it would trigger floor heating for few minutes, and after that floor heating would just stop and switch off.

Any one have any suggestions?

Thank you in advance,
