Intergas HRE 36/10 , R8810 Bridge 2 cotrollers 22 HR92

Hi,
My self installed, professionally commissioned system has been running swimmingly. for three years.

Settings for the boiler Parameter C has has always been set to 1= Step Modulation during CH Operation.

Question : Why not set parameter C to 2= CH output controlled by OT Controller?

Thanks if anyone can enlighten me.

If you have the option of C = 2 on your boiler, I would suggest using it.
