Warrick 26C1C0A LWCO Board 321894-708 Fail-Safe Reliability: Mechanical spring return

Fail-Safe Reliability: Mechanical spring return ensures the valve returns to the normally open position during power interruptions

Pressure switches are safety devices calibrated to the specific venting and airflow design of the furnace

To achieve automatic reset

The switch is calibrated to a fixed open temperature of 140 degrees F

Warrick 26C1C0A LWCO Board 321894-708 Fail-Safe Reliability: Mechanical spring returnThe Warrick 26C1C0A is a heavy duty, series 26 low water cut off (LWCO) controller designed for reliable boiler water level control. This conductive liquid level control features an auto reset function, ensuring the burner circuit restores power automatically once the water level rises above the probe. Operating on 120 VAC, the 10K ohm sensitivity is ideal for standard feedwater applications, providing a precise probe voltage to prevent dry firing.
