Resideo L4029E1227 Control 320788-703 this direct-actingThe Resideo L4029E1227 is a manual reset high limit control designed for critical fan shutdown in warm air heating systems. This normally closed SPST switch acts as a safety interlock, opening the circuit when the sensed air temperature reaches the fixed 125F high limit stop, typically indicating a potential fire condition or significant overheating within the ductwork. Featuring a 3 inch element insertion length, this bimetal actuated sensor provides
