About Thermostat Modules

A thermostat module is a component of a thermostat system. These modules add functionalities or features to the overall thermostat system and can vary in the complexity and capabilities they provide. For example, a thermostat module may facilitate wireless communication, zoning, programming, or smart-home integration. Some models offer occupancy and humidity sensing.

Our selection of thermostat modules includes models compatible with line-voltage and 24-volt Honeywell thermostats.
