Diversitech ct101wa Smart Thermostat Central Hvac

Product Description

The DIVERSITECH ct101wa is a WiFi-enabled, ENERGY STAR certified smart thermostat designed for central ducted HVAC systems in residential and light commercial applications. It features a 3.5 square inch touch LCD and is hardwired at 24 volts for reliable power. The ct101wa supports multi-stage operation — up to 4 heat and 2 cool stages for heat pumps, and 2 heat and 2 cool stages for conventional systems — making it suitable for a wide range of system configurations. Licensed HVAC technicians install this thermostat as a direct control interface for central heating and cooling equipment. Keypad lockout, auto changeover, and cooling fan delay are included in the advanced feature set.

The ct101wa is compatible with conventional ducted HVAC systems including gas, oil, and electric furnaces, heat pumps with or without auxiliary heat, dual fuel systems, hot water systems, and geothermal setups. It is suited for residential new construction and retrofit installations where smart home integration is required. Scheduling flexibility supports 7-day, 5-1-1, and non-programmable modes. The WiFi programming interface allows remote access and schedule management. IAQ features include humidity control and an IAQ fan mode for indoor air quality management.
