Warrick 26C1C0A LWCO Board 320788-704 It utilizes standard flame rectificationThe 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.
