Description
The Honeywell T6861 Horizontal Digital Thermostat is designed for efficient control of 2-pipe and 4-pipe fan coil systems, supporting cool-only, heat-only, and manual or automatic changeover modes. With manual or automatic 3-speed fan and water valve control, it ensures precise temperature management while maintaining energy efficiency. Its sleek, modern design makes it ideal for offices, hotels, and residential buildings.
Energy-saving functions adjust heating and cooling set points automatically, and when activated, the thermostat locks all buttons except the installer setup key. In automatic mode, fan speed adjusts based on the temperature difference, and once the set point is reached, both the fan and valve shut off to conserve energy.
