Honeywell TH6320U2008/U T Series Programmable Thermostat – Multi-Stage Control for Heat Pump and Conventional Systems
The Honeywell T Series TH6320U2008/U thermostat is engineered for compatibility with a wide range of residential HVAC applications, including up to 3 heat/2 cool heat pump systems and 2 heat/2 cool conventional systems. It provides precise temperature control with selectable programming modes and a 1°F differential to support energy efficiency and system performance.
Application Overview
Designed with contractors in mind, the T Series thermostat uses the Universal Wall Plate (UWP) system for efficient installation and service. The thermostat can operate in programmable or non-programmable modes (7-day, 5-1-1, or 5-2), allowing flexibility based on system requirements and occupant preferences. The unit supports auto or manual changeover and includes a large-format backlit display for visibility in varied lighting conditions.
