Problem description
IDEAS.Templates.Heating contains templates of (idealised) heating systems. Their control behaviour (explained in IDEAS.Templates.Heating.BaseClasses.HysteresisHeating is described as follows:
"""
This model represents an ideal heating system with a hysteresis controller. It reacts instantly when the zone temperature input TSensor is below TSet by supplying the nominal heat flow rate QNom. This heat flow rate is maintained until TSensor is above TSet+dTHys.
"""

Simulation results however show that this is not the hysteresis control that is modelled, which is shown by the following simulation results of IDEAS.Templates.Examples.IdealRadiatorHeating:

The hysteresis acts between TSet-dTHys and TSet.
