Controler co2/environment compatibility?

I have a Sentiel EVC-1 that controls temp/Rh/and has night device, and co2 photo senser and fan shut off. All important. I want to add a Co2 Monitor and controler that regulates the co2 along with the Sentiel EVC-1. If I was to piggyback the Sentiel into say a Cap Co2 montitor, or Titian Co2 monitor will this work. Will all features work with each other? I like the options that the EVC1 give me. It seems that all the total controlers I see dont offer all the options. Does my question and statement make since?
