HVAC pneumatic thermostat for commercial systems

The SIEMENS 192-200 is a direct-acting pneumatic thermostat designed for single-pipe heating and cooling control in commercial HVAC installations. It manages a temperature range of 45 to 85 degrees Fahrenheit using a bi-metal sensing element. The unit operates on a 3 to 15 psi control air pressure signal with a matching throttling range. It is built for vertical mounting on a wall or panel.

Brass barb connections and bi-metal reliability

The thermostat body accepts 5/32 inch barb fittings for quick connection to polyethylene or nylon tubing without ferrules. A maximum supply pressure of 30 psi and air consumption of 25 scim suit standard pneumatic mains. The bi-metal element requires no electrical power, eliminating wiring runs and transformer sizing. An ambient rating of 140 degrees Fahrenheit allows placement near mechanical equipment or in unconditioned spaces.

Replaces legacy pneumatic stats with identical range

This model directly replaces older single-pipe direct-acting thermostats that use the same 3 to 15 psi span and 45 to 85 degree Fahrenheit setpoint range. The jump is worth it when the existing housing is damaged, calibration has drifted beyond adjustment, or the barb ports are stripped. It is not suited for two-pipe systems, reverse-acting sequences, or electronic DDC integration.

Questions about this item

What air-pressure range does the 1-pipe pneumatic interface use, and what does it cap at?

The thermostat operates on a 3 to 15 psi control signal and the internal components are rated for a maximum supply pressure of 30 psi.

What mounting style and dimensions does the 192-200 need to fit on the wall?

It mounts vertically and measures 3 3/8 inches high, 2 1/8 inches wide and 1 5/8 inches deep.

How is the 5/32 inch barb air connection installed, and what step is often missed?

Push the 5/32 inch tubing onto each barb until it seats fully; the step people skip is verifying a leak-free seal at 30 psi before commissioning.
