Honeywell ythx1200w5 Smart Thermostat 4H/2C Heat Pump

Product Description

The HONEYWELL ythx1200w5 is a WiFi-enabled smart thermostat designed for both residential and commercial HVAC applications. It features a 5-inch touchscreen display in a white finish and supports up to 4-heat/2-cool heat pump systems or 3-heat/3-cool conventional systems. The thermostat integrates with a room sensor to extend comfort control beyond the single thermostat location. It provides full control over heating, cooling, and indoor air quality (IAQ) functions through an intuitive on-screen interface and remote WiFi connectivity. Licensed HVAC technicians typically handle installation in multi-stage or zoned systems where precise staging control is required.

The ythx1200w5 is suited for residential and light commercial installations where multi-stage heating and cooling systems are in place. It supports both heat pump configurations with auxiliary and emergency heat staging and conventional forced-air systems with up to three stages of heating and three stages of cooling. The included room sensor allows temperature averaging or room-priority control, making it a practical solution for open floor plans or spaces with uneven heat distribution. Indoor air quality accessories can be wired and controlled through the thermostat interface.
