This is a simplified model of a two-pipe fan coil unit for heating. It is intended to be used in a case where the room thermal loads are provided as time series, and hence it takes the load as an input.
A PI controller tracks the load. The controller output signal is mapped linearly to both,
The impact of an unmet load on the room air temperature is assessed with Buildings.DHC.Loads.BaseClasses.SimpleRoomODE.
