Marley Engineered Products TA2AW Thermostat

For professional contractors updating or repairing Marley Engineered Products baseboard heaters, the Marley TA2AW Double Pole Thermostat provides reliable, line-voltage control for both residential and commercial zones. This DPDT (Double Pole, Double Throw) thermostat acts as a double break control, ensuring that both power legs are physically disconnected when the unit is in the Off position. Engineered for seamless integration, this 22A thermostat is specifically designed for the QMark 2500 Series and Berko heating units, supporting a voltage range of 120V to 277V. The Navajo White finish ensures a clean, professional appearance that matches standard heater housings while the 40°F to 100°F temperature range allows for precise environmental calibration. Utilizing heavy-duty lead wires for quick field connections, the Marley TA2AW is the technician's choice for a robust electric heater thermostat replacement that maintains high-amperage loads without compromising on safety or switching reliability.

• Double Break Protection: Provides a positive "off" by breaking both lines of the power supply for increased safety.
• High Amperage Rating: Reliable switching capability up to 22 Amps at 120/277VAC to handle full-length resistive loads.
• Universal Series Compatibility: Designed for direct installation into the terminal box of Marley 1800, 2500, and C2500 series heaters.
• Industrial Durability: Rugged DPDT contact mechanism built to withstand the frequent cycling of commercial heating applications.
• Easy Installation: Features integrated lead wires and "easy-out" knockouts for rapid field wiring without full heater disassembly.

Can the TA2AW be used as a standalone wall thermostat?
While technically a line-voltage control, the TA2AW is specifically designed as a "built-in" or unit-mount accessory that installs directly into the heating unit's wiring compartment rather than a standard wall box.

What is the difference between this and a single-pole thermostat?
A single-pole (SPST) thermostat only breaks one side of the power line, whereas this double-pole (DPST/DPDT) model breaks both conductors, which is often a requirement for 208V or 240V circuits to ensure no voltage remains at the element when off.

Will this thermostat fit other brands of baseboard heaters?
The TA2AW is engineered for Marley Engineered Products (QMark and Berko). While dimensions may appear similar to other brands, heat-sink alignment and mounting bracket spacing are proprietary to Marley series heaters.
