Field technicians prioritize this mechanical thermostat for its bimetal disc accuracy and simplified wiring, ensuring stable thermal management without the complexities of digital interfaces.

• High Amperage Rating: Engineered to support up to 25 Amps, making it suitable for multiple heaters or high-wattage electric heating systems.
• Integrated Fan Control: Includes a dedicated fan switch to manage airflow sequencing alongside heating elements.
• DPDT Switching: Provides a "true off" position by breaking both sides of the line for enhanced safety during maintenance.
• Universal Compatibility: Direct drop-in replacement for professional QMark/Berko blower units and 3UF heater series.
• Durable Construction: Heavy-duty mechanical design eliminates the failure points common in electronic controls in high-dust industrial environments.

Is the 5813-2059-000 compatible with my specific heater?
This Marley thermostat is verified for use with QMark and Berko models DH1521D, DH1523D, DH1543D, and heaters using manufacturer numbers 3UF59 through 3UF63. Always cross-reference your heater's nameplate before installation.

What is the benefit of a DPDT thermostat over a single-pole unit?
A Double Pole Double Throw (DPDT) switch provides a positive "off" position by disconnecting all ungrounded conductors, ensuring no power reaches the heating element when the control is turned down.

Can I use this for ceiling-mounted blower heaters?
Yes, this Marley Engineered Products 5813-2059-000 is specifically designed for blower air heaters and supports both wall and ceiling mounting configurations depending on the junction box setup.
