Recommended replacement controller for a Vaillant aroTHERM plus

Hi. I've got a Vaillant aroTHERM plus heat pump and it was installed with these modules:

  • VWZ AI control interface
  • VRC 700 weather compensation control
  • VR 921 sensoNET internet gateway

The whole thing is installed in my garage. The VRC 700 is measuring the "room temperature" of my garage, so I can't use it in "Active" mode where it would automatically adjust the flow temperature depending on how cold my house is.

I'm currently using Tado to turn the heating on and off. I'm thinking of no longer using Tado to control the heat demand.

The VRC 700 doesn't seem to support adding a wireless temperature sensor inside my house. Would people recommend replacing the VRC 700 with a different module that supports a wireless temperature sensor? If yes, which Vaillant module would you recommend replacing it with?
