sensing temperature at the controller location rather than the return air at the unit

Automatic Reset Function: Eliminates the need for manual intervention by allowing the circuit to close once the system cools

corrosion-resistant materials—often polypropylene—this housing is designed to mitigate resonance while maintaining structural integrity under high static pressure

unlike manual reset switches that require a physical button press

Always verify compatibility by cross-referencing your unit's model and serial number with the Bard parts list or contacting our technical support team

Siemens Building Technology 184-114 Restrictor 319825-402 sensing temperature at the controllerFor veteran HVAC contractors managing legacy building automation systems, the Siemens Building Technology 184 114 Restrictor is a critical component for stabilizing pneumatic control circuits. This Type 3 Tee Restrictor is engineered to deliver a precise 40 scim flow rate (11 ml sec) at a standard 22 psi calibration pressure. Designed specifically for integration with one pipe pneumatic transmitters and receiver controllers, it ensures the steady
