Product Description

Zen Thermostat™ is a smart home automation tool that fits beautifully into your home or office environment. The LED screen provides clear and simple feedback. Icons only display when they are required. When left inactive, the display simply fades away. Zen Thermostat™ is available in black or white so it blends seamlessly into your existing interior design.

Touch Zen to wake the display. Use the left and right arrows to switch between heating, cooling and fan. Use the up and down arrows to set the temperature. Once you are done, the display fades, but Zen Keeps working in the background.

Zen Thermostat™ is compatible with leading connected home platforms so you can easily expand without needing to run a separate home automation system. It uses Wi-Fi connections to communicate with your home wireless network or Wi-Fi compatible automation hub, so you can control Zen from right inside your existing apps. This wireless room thermostat is an efficient and elegant solution for your smart home automation needs.

Zen Thermostat™ comes complete with everything you need in the box. The interactive installation guide generates a personalized set of installation and wiring instructions. The easy to follow, step-by-step approach makes the installation stress free no matter which thermostat you are replacing.

If you're not comfortable installing Zen Thermostat™ yourself, we've made it easy for your HVAC contractor to get you up and running quickly too.
