The Honeywell L4029E1219 reset limit control opens a line or low voltage circuit if the air temperature reaches an extreme level at controller location. Primarily used as a fire thermostat in the duct work of air conditioning and ventilating systems. Internal snap-acting switch actuated by a bimetal strip inserted directly into the air stream responds rapidly to temperature changes. If the circulated air reaches a critical temperature indicating a fire, the limit control shuts off the fan, thus preventing spread of fire. It is also suitable for use with any warm air furnace to provide positive lockout of the burner in the event of fan failure. Requires a manual reset.
