Programmable Touchscreen Thermostat with Humidity Sensor

Manufacturer Part Number: TCONT303AS42DA

The TCONT303AS42DA offers a 5-inch diagonal touchscreen and built-in humidity sensor for programmable temperature and humidity control. Users can choose seven-day, 5/1/1-day, or non-programmable operation, making the thermostat adaptable to different routines. It supports applications up to four heating and two cooling stages, including gas, oil, electric, heat pump, and dual fuel configurations. A bright white finish provides a neutral appearance, while the large touch interface brings scheduling and comfort settings together at the wall.

Remote wired indoor or outdoor sensor options extend the thermostat’s measurement choices. A compatible indoor sensor can provide the control input by itself or be averaged with the thermostat’s internal sensor. The model also includes cooling dehumidification and a humidifier relay. A common connection is preferred but not required when the included two AA batteries are used, and battery operation enables armchair programming. The shortened TCONT303AS42D table entry is listed separately because its three-heat, two-cool staging differs from this detailed page.
