Monitors air quality.

GLAS provides you with the information you need to help make your home healthier. The smart thermostat monitors relative humidity, total Volatile Organic Compounds (tVOCs), and equivalent CO2 (eCO2) levels indoors. It even reports pollen and air quality outdoors – especially helpful for asthma or allergy sufferers. And with features like fan runtime options, smart circulation, and smart ventilation, you’ll have more control over your air quality than ever before.


What’s behind GLAS?

Johnson Controls invented the room thermostat 135+ years ago. With your family’s health, comfort, and energy savings in mind, we reinvented it with GLAS. The smart thermostat can help create an efficient and comfortable space, and its clean translucent interface reimagines any space.
