Chapter 12, Problem 5SQ
When the thermostat contacts close, the blower motor starts and heating element #1 turns on. After a time delay heating element #3 turns on, but heating element #2 never turns on. Which of the following could cause this condition?
- a. Timed contact T1 did not close.
- b. Heating element #2 is open.
- c. CR relay coil is open.
- d. The flow switch is defective and did not close its contacts.
FIG. 12–10 Air flow must be present before heating elements can be energized.

I need immediate help with my SIMULINK model. I don't know why but no matter how much a increase or decrease Kc or TI, the graphs are the same. C'A0(s) is the disturbance going through G'D(s). Please check my transfer function blocks by taking the laplace transform of the equations. Any suggestions is welcome greatly! thanks
