which word best goes in the blank?

Explanation:

The context is about adjusting temperature in the classroom. A "thermostat" is a device used to control temperature, which fits the sentence "Please turn the ____ to a reasonable temperature". A generator produces electricity, electricity is a power source, and a pendulum is a swinging device, none of which relate to temperature control as needed here.
