It features a large LCD digital display with blue backlight for clear viewing of temperature, mode, and set point even in low light. The unit ships in a polar white, low-profile housing with a gently curved bezel that blends with most interiors. Controls and operation: The thermostat uses capacitive touch sensing rather than physical buttons. Three touch-sensitive graphic areas let you change modes, adjust fan speed (low/high/auto), and switch fan control between Auto and On. A single tap on any input lights the display so you can instantly see current settings. The CT thermostat can operate in manual or automatic modes and supports both non-ducted and ducted rooftop air conditioning units. Construction and display: Built from durable materials for reliable long-term use, the Single Zone LCD Thermostat includes a large custom display for easy readability. The blue backlight and clear digital readout make temperature and mode information simple to monitor at a glance. Design notes and compatibility: The upgraded polar white finish is designed to complement RV and trailer interiors. This thermostat is generally specific to the appliances listed and is not a universal replacement — do not use it outside the applications specified in the installation and operating instructions.
