SYSPHS12 — Use of == comparison with Real in not valid outside a function in Modelica

On p.98 in Figure 93: Heater Control State Machine Diagram and Figure 94: Humidifier Control State Machine Diagram.

The StateMachines HeaterControlSM and ControlStateMachine have comparisons using == with Real, which is invalid in Modelica outside a function.

Examples:

when (modeIn.rSig==0)

when (waterVolumeIn.rSig==0)

At least in Wolfram SystemModeler this is reported as invalid and will not execute.
