Engineered for compatibility with specific Bard wall-mount units

this unit is classified as a heavy duty damper actuator

these thermostats are suitable for low-voltage applications where SPST switching is required

The tapped cap allows for easy blow-off valve installation to facilitate inline flushing without system teardown

If the millivoltage drops below the dropout threshold of the gas valve

Trane SWT4230 Limit Switch 319847-401 Engineered for compatibility with specificThe Trane SWT4230 Limit Switch is a genuine OEM replacement part engineered for high temperature circuit protection in residential and commercial heating systems. Classified as an L215F limit switch, this SPST (Single Pole Single Throw) thermal cut off is designed to open an electrical circuit when the sensor detects a temperature rise reaching 215F. This precise interruption prevents heat exchanger damage and ensures safe operation within the supply
