Pneumatic Thermostats
Available19 products
Pneumatic thermostats respond to changes in temperature by increasing or decreasing the air pressure in a series of air-filled tubes. The change in pressure signals controllers or powers devices like dampers or valve actuators directly. Pneumatic thermostats are most often installed as replacements in older constructions with existing pneumatic systems, including schools, hospitals, and commercial buildings. They are not suitable for newer constructions without a supporting pneumatic system in place.
Action
Single-Temperature Thermostats
These thermostats have a single setpoint to control heating and cooling systems at one temperature for basic temperature control in older schools, hospitals, and commercial buildings. Pneumatic thermostats regulate the temperature using compressed air for power.

Dual-Temperature Thermostats
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.

Dual-Temperature Energy Management Thermostats
Energy management thermostats have an adjustable temperature differential, also known as a deadband, between the heating and cooling setpoints. The differential is the number of degrees between the setpoint and when the system turns on or off. Users determine the temperature span when the HVAC system doesn't use any power for heating or cooling, so they have more control over energy consumption than with other pneumatic thermostats. These are dual-temperature thermostats, so users can determine different temperature setpoints to save energy when a building, such as a school or office, is unoccupied. These pneumatic thermostats are powered by compressed air.
