HVAC On Off Control Basics

The video tutorial explains how to control the heat output from an electrical heater manually and automatically using a bimetallic strip thermostat. It describes how the strip bends with temperature changes to control the circuit. The tutorial also covers on-off control systems for heating or cooling, highlighting their limitations in maintaining a stable temperature and suggesting improvements by using smaller time intervals.

Describe the process of how a thermostat turns a heater on and off.

How can dividing time intervals improve temperature control in a room?
