Emerson manufactures several lines of universal thermostats designed to work with every HVAC system. The thermostats are branded under the name White-Rodgers, a sub-brand of Emerson Climate Technologies.
Universal thermostats offered by Emerson include the Sensi Wi-Fi thermostat. This option allows users to set temperatures and schedule changes from anywhere in the home. In most cases, this thermostat doesn't require a C wire for installation, and it features an easy-to-read LCD screen for added convenience.
The company also manufactures universal programmable and non-programmable thermostats. The programmable models feature four-wire installation and are compatible with almost every HVAC system, and some feature dehumidifier and humidifier options. Non-programmable universal thermostats work with 24-VAC or millivolt systems for ease of installation.
