The impedance model represents a series
connection of a resistor and either an inductor or capacitor.
 
The linear impedance connects the voltage v
with the current i by v =
Z*i. The resistive component is modeled
temperature dependent, so the real part R_actual =
real(Z) is determined from the actual operating
temperature and the reference input resistance
real(Z_ref). A 
conditional heat port is considered. The reactive component
X_actual = imag(Z) is equal to
imag(Z_ref) if frequencyDependent =
false. Frequency dependency is considered by
frequencyDependent = true, distinguishing two
cases:
imag(Z_ref) > 0: inductive caseX_actual is proportional to
f/f_refimag(Z_ref) < 0: capacitive caseX_actual is proportional to
