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.

Simple upsell: The T Series features a snap-together design that enables you to easily move customers from a non-connected to a connected thermostat when they’re ready for Wi-Fi – without having to remove the connector and cover plate.
