The Honeywell T Series is a portfolio of non-connected and Wi-Fi connected thermostats designed with contractors in mind. With an interface you know, features you trust and the Honeywell quality you depend on in a sleek new aesthetic, the non-connected T Series thermostats are setting the new standard for simple installation, operation, and maintenance.
T4 Pro
NON-CONNECTED SOLUTIONS that simplify selection, installation and upsell.
Simple selection: We've streamlined our legacy portfolio of 20+ non-connected FocusPRO and PRO thermostats down to just six non-connected T Series thermostats, helping you simplify inventory management and product selection.
Simple installation: All T Series thermostats use the same UWP mounting system, helping you standardize your training program, install process and truck stock. Install one and you can install them all.
