The Siemens/Powers 192 and 193 Series pneumatic room thermostats are used to provide various types of control of pneumatic valves and damper actuators in heating and air-conditioning systems. All use sensitive bimetals to respond to temperature change to modulate control air through a flapper nozzle. These pneumatic thermostats produce a proportional output signal that modulates pneumatic valves and damper actuators in response to load changes in the space. A variety of high-volume and low-volume output thermostats are available to meet the functional requirements of any building automation system. The 192 and 193 Series pneumatic thermostats are available in one- and two-pipe, dual temperature, day/night and auto-changeover configurations. Each 192 and 193 Series chassis includes a wall plate for thermostat installation using a variety of rough-in installation kits. Air connections are made with 5/32 in (4 mm) O.D. plastic tubing, directly to the thermostat chassis for retrofit applications or with plug-in adapters that slide into the wall mounting plate.
