ColorTouch programmable commercial thermostats (Models T8850 and T8900) come with Wi-Fi on board, delivering integrated Wi-Fi in a sleek design. Model T8900 has humidity control and Model T8800 comes without Wi-Fi connectivity for environments where Wi-Fi is not needed. All three ColorTouch models have a multifunctional, simple-to-use, touch-screen interface. The color touchscreen can be programmed to display company logos, advertisements, or promotions, as well as a picture gallery of up to 100 files to be used as a slideshow. ColorTouch commercial thermostats comply with California’s Title 24 requirements, including equipment fault detection diagnostics (FDD). Another key feature includes automated demand response (ADR), which enables users to participate in utility-generated load-shedding events, as well as the ability to support the handling of specific signals from the utility provider.
