@Nando.Tolboom

what else would you like to know?

Just a description of the whole setup really.

Underfloor?
System Volume? Any volumiser in play?
Primary pipework size
Other pipework in play

@Nando.Tolboom

In my view, it has to do with the control of the expansion valve and the state of the refrigerant and the hystereris that is present in the evaporator.

I need to dig into the work that @John_C is doing to understand this more.
