Marley Engineered Products 5813-2050-000 Thermostat

The Marley Engineered Products 5813-2050-000 Thermostat is a high-performance single pole single throw (SPST) replacement component engineered specifically for heavy-duty electric heater temperature control. This OEM thermostat assembly is the factory-standard internal control for a wide range of Marley-branded heating units, including QMark, Berko, and Fahrenheat series. Designed to handle the rigorous electrical demands of fan forced heaters and industrial convection units, this 2-wire thermostat provides precise thermal regulation to prevent equipment overheating and ensure consistent occupant comfort in commercial or residential environments.

When performing field service on units like the Fahrenheat FUH54 or QMark MWUH series, using this genuine HVAC replacement part is critical for maintaining the original equipment’s UL listing and operational integrity. The robust mechanical switch mechanism is built to sustain frequent cycling under high-amperage loads, reducing the risk of premature contact welding or calibration drift. Whether you are troubleshooting a unit that fails to kick on or one that is cycling erratically, this Marley 5813-2050-000 offers a direct-fit solution that eliminates mounting headaches and specialized wiring modifications for the technician.

• Precise Thermal Regulation: Features advanced control algorithms and a calibrated mechanical sensor to maintain tight temperature differentials.
• Broad Unit Compatibility: Verified for use in Marley FUH, HUH, and MWUH series electric space heaters, ensuring a seamless drop-in replacement.
• Industrial-Grade Durability: Constructed with heavy-duty contacts designed for the high-draw requirements of 208V and 240V heating circuits.
• Simplified Installation: Standard 2-wire configuration allows for rapid field replacement, minimizing downtime for the end-user.

What heater models is the 5813-2050-000 compatible with?
This thermostat is primarily designed for the Marley FUH54, FUH724, and MWUH series of fan forced heaters, as well as several Berko and QMark industrial unit heaters.

Is this a single pole or double pole thermostat?
The 5813-2050-000 is an SPST single pole thermostat. For applications requiring a positive "off" position that breaks both lines of power, a double pole (DPST) alternative must be utilized.

Can I use this for baseboard heater control?
While Marley manufactures baseboard components, this specific part is optimized for the internal control circuits of industrial unit heaters rather than standard wall-mounted baseboard applications.
