(a)
Interpretation:
The manipulated variable in a thermostat controlled home heating system is to be identified.
Concept introduction:
A control system is a system which regulates or monitors the behavior or working of other devices/systems using control loops. It can be used to control single device or large industrial processes. There are two types of control system which can be used to control the processes. These are feedback control system and feedforward control system.
Controlled variables (CVs) are the process variables which can be controlled, and its desired value is known as the set point.
Manipulated variables (MVs) are the process variables which are adjusted by the controller to keep its value close to the set point.
Disturbance variables (DVs) are the process variable which affects the controlled variables, but they cannot be manipulated and are associated with any changes in the operating environment of the ongoing process.
(b)
Interpretation:
The controlled variable in a thermostat controlled home heating system is to be identified.

(c)
Interpretation:
The adjustment of the manipulated variable in a thermostat controlled home heating system is to be determined.
