 Thermostats Thermostats are devices that: 1.Regulate temperature:   Control the temperature in a building or space. 2.Sense temperature changes:  Detect changes in temperature and send signals to HVAC equipment. 3.Maintain setpoints:  Keep the temperature at a set level, within a specified range. Types of thermostats: 1.Mechanical thermostats:  Use a physical mechanism to sense temperature changes. 2.Digital thermostats:   Use electronic sensors and displays to regulate temperature. 3.Smart thermostats:  Can learn occupancy schedules, adjust temperature, and be controlled remotely. 4.Programmable thermostats:  Allow for scheduling temperature changes. Key characteristics of thermostats: 1.Accuracy and reliability. 2.Sensitivity and response time. 3.Adjustability and programmability. 4.Compatibility with HVAC systems. 5.Energy efficiency and optimization. Factors affecting thermostat performance: 1.Proper installation and calibration. 2.Regular ma...
