Lochinvar & A.O. Smith 100148402 Temp Limit Els PW 29614 This high-limit switch functions asThe Lochinvar & A. O. Smith 100148402 Temp Limit is a critical safety component designed specifically for high efficiency commercial and residential boilers. This 330C Over Temp Limit switch (often referred to as the heat exchanger high limit) acts as a primary fail safe by monitoring thermal conditions at the heat exchanger. When temperatures exceed the 330C (626F) threshold, the 100148402 limit switch breaks the control circuit to initiate an
