Description
The Honeywell TP971B2043 Pnematic Day/Night Thermostat is used in commercial HVAC systems that use pneumatic control. This thermostat operates through pressure of air to regulate heating or cooling equipment such as valves and dampers. During the night, it operates at 20 PSI and offers a comfortable daytime temperature during the day. At night, the pressure is set at 25 PSI for setback temperatures and to conserve on energy. This pneumatic control is ideal for large buildings because it enables the building to regulate the temperature and energy use through the programmed control of temperature.
