Resideo ythx1200w5 Smart Thermostat 4H/2C Heat Pump Wifi

Product Description

The RESIDEO ythx1200w5 is a WiFi-enabled smart thermostat designed for residential and commercial HVAC applications. It supports up to 4-heat/2-cool heat pump systems and up to 3-heat/3-cool conventional systems, making it a versatile single-device solution for a wide range of installations. The unit ships in white and features a 5-inch touchscreen display. It includes a room sensor for remote temperature monitoring and integrates indoor air quality control alongside heating and cooling management. Licensed HVAC technicians are the primary installers for this thermostat in both new-construction and retrofit scenarios.

The ythx1200w5 is suited for residential and light commercial installations where full WiFi connectivity and smart sensing are required. Its compatibility with both heat pump and conventional system configurations reduces the need for multiple thermostat SKUs across a service fleet. The included room sensor allows temperature readings from a location away from the main unit, helping to address comfort complaints in spaces where the thermostat placement is not representative of the occupied zone.
