Hot water control OT connection Logic C30

Hello, I recently replaced my V3+ wireless receiver with an Extension kit to enable OpenTherm wiring on my Logic C30 boiler. While the boiler appears to be modulating as expected and the wireless sensor is requesting heat, I have gained hot water control in the app. I am unsure of the purpose of this feature since hot water is typically activated when a tap is turned on in a combi boiler. The preheat function is disabled, and the temperature control seems ineffective. I would appreciate any insights or experiences from others who have encountered this? Should I just disable this on the pro app?

    You should be able to control the hot water temperature on the boiler using the Tado app if it’s connected with Opentherm. I usually leave mine set to 44 and turn it up slightly if I’m having a bath.

    Interesting, which boiler do you have?
