Dual-temperature thermostats allow users to determine two separate temperature setpoints for different times of the day, week, or year. They save energy costs for schools or commercial buildings that are occasionally unoccupied. When the supply pressure to the unit changes, the thermostat automatically switches between the setpoint temperatures. Some thermostats also have a manual indexing switch that allows users to restore the prior temperature setting of an individual thermostat without affecting other thermostats in the system. The indexing switch can be unlatched manually, or it will automatically reset with the next cycle. These pneumatic thermostats are powered by compressed air.
