The L4029E is a Limit Control that Breaks on Rise with Manual Reset. This control consists of a Bimetal disc with an aluminum backed wax and ceramic insulator. This product is designed to reduce catastrophic failures from overheating if the heat source rises past setpoint by opening. It is designed for use in heating and plumbing applications, including baseboard, convectors, radiant panels, boilers, furnaces, water heaters and others. Applications such as space and process heating where remote or excess temperature may be common typically do not require the automatic reset feature found in thermostat controls.

The L4029E1219 Fixed/Rise Control is a direct replacement for the Honeywell C9403A1012 control for furnace models 15800, 15801 and 15802. This control is designed to be compatible with a heating system that uses a high limit (LIMIT) to shut off the heat and a manual reset (MR) switch to start operation of the unit again.

DESCRIPTION: This Honeywell L4029E111 limit control is built for use with all types of indoor heating and cooling equipment. The L4029EB1/X UPB-rated limit control with manual reset features a full rise thermal-magnetic actuator which moves the upper adjustable thermal limit above the bottom fixed limit by a full 1 inch to provide additional protection against over-temperature damage.

The Honeywell L4029E1219 Limit Control is designed for use with upflow furnaces and boilers. Use the Manual Reset option to reset temperatures that have risen out of range. It also features a fixed limit at 165 degrees Fahrenheit. This two-wire control uses a C-wire to connect to the common wire (C) circuit, which is activated by a rising temperature. The other wire is for the limit output circuit, which is activated when the set point has been reached and has not been reset.

Fixed Temperature control with manual reset. Rated for up to 165 F Rise, 40 Amp, 480 Vac. L4029E1219
