this auto-reset limit switch features a specialized 100-160°F temperature range

Technicians often see the blower fan running continuously or the furnace short-cycling (shutting down before the thermostat set-point is reached)

As a critical component in the diagnostic and protection circuit

This ambient air temperature sensor utilizes a high-precision NTC thermistor to provide real-time atmospheric data to the primary control board

prepackaged enclosed pilot relay designed to streamline Building Automation Systems (BAS) and HVAC/R control applications

Trane SWT2515 Pressure Switch Els PW 17895 this auto-reset limit switch featuresThe Trane SWT2515 is a high precision HVAC pressure switch calibrated to a 1. 36" WC setpoint for critical safety monitoring in gas furnaces and air handlers. This SPST (Single Pole Single Throw) air pressure sensor acts as a primary safety interlock, ensuring the draft inducer motor generates sufficient negative pressure before the ignition sequence begins. Designed for maximum reliability in high cycle environments, the SWT2515 provides a 1 4" barb
