Fixed-setpoint manual reset limit control that opens a circuit when air temperature reaches 240°F, then locks out until manually reset. Designed for furnace and air handler ductwork to prevent fan operation during overtemp conditions and provide burner lockout on fan failure. Bimetal element responds rapidly to temperature changes; resets when temperature falls approximately 25°F below setpoint.
