The Complete Handbook of Thermostats

Thermostats are deceptively simple-looking devices that control some of the largest energy loads in buildings. Yet specification sheets are dense, installation mistakes are common, and the difference between a system that runs efficiently and one that wastes energy often comes down to thermostat setup and calibration.

This handbook cuts through manufacturer marketing and online confusion to deliver practical, concrete knowledge for HVAC professionals, facility managers, system builders, and equipment resellers. You'll learn what thermostats actually do under the hood, which specifications matter and which don't, how to choose the right device for your specific application, how to install and commission them correctly, how to diagnose and fix common problems, and how to build a sustainable business around thermostat service and sales.

Whether you're troubleshooting a faulty heating cycle, evaluating smart thermostats for a commercial retrofit, or building a resale business, this reference gives you the technical foundation and real-world workflows you need to work with confidence.
