Description
The Honeywell T6861 Vertical Digital Thermostat is engineered for precise control of 3-speed fans and valves in fan coil systems, making it perfect for offices, hotels, and residential buildings. With both manual and automatic fan speed control, it ensures efficient operation and comfort. The thermostat measures room temperature using its integrated or external sensor and maintains the set point via on/off valve control.
Featuring a modern vertical design, it includes energy-saving functions such as fixed dead bands for automatic changeover and lockable buttons when energy-saving mode is activated. In automatic fan mode, fan speed adjusts based on the difference between room temperature and the set point. Once the desired temperature is reached, both the fan and valve shut off to conserve energy.
