No the system you have is a piv system with a built in heater. Still not sure why the builder would fit one of those in a new build unless there's some eco regs that I'm not aware of that allows it to meet code.
Be aware that that setup you have has a filter setup that needs yearly replacing. Some have a reusable filter that just needs a clean.
Thanks for all your help, at least I have now got it set up properly. It had been left on all the default settings. The filter changes on this model are every 5 years.
