Bugfix in heatsource for condensing gas boiler and modification of start temp in DummyBuilding
Fan coil unit model with control and example. WIP
Improved FCU with heat exchanger and natural convection
Working example for FCU.  Next step is adapting the air flow rate based on control position
Tuned FCU model
FCU scales with nominal power
Adding back old approach to heatSource interpolation
Bugfix in HeatSource_CondensingGasBurner_OldApproach and addition of Boiler_OldApproach
This example, which did not work with previous boiler implementation, works again with OldApproach version of the boiler
