The conceptual diagram of an open loop control for the heating of a room is shown below.

The room achieves a given temperature as a function of the added heat from the radiator and the heat loss Q_L from the room. But, for simplicity, ignore Q_L as being too slow to influence the immediate response. Draw a block diagram of the system that determines T_Room, indicating on the diagram which parts of the conceptual sketch correspond to the blocks. Assume the controller switch is a simple off/on (0,1) and the furnace responds with a gain G to produce heat at a rate Q.
