Marley Q-Mark TA1A Line-Voltage 1-Pole Thermostat, 120-277V AC, 22A

The Marley Q-Mark TA1A is a 1-Pole line-voltage thermostat built to deliver dependable heating control for commercial and residential electrical installations. Rated for 120-277V AC operation with a 22A capacity, it is engineered to handle the electrical demands of resistive heating loads such as baseboard and wall-mounted heaters. This thermostat is available in Navajo White and Northern White finishes, letting electricians match the device to the surrounding wall finish while keeping the same 1-Pole, 120-277V AC, 22A performance across both options. Its single-pole switching mechanism provides straightforward, single-circuit control for new construction and renovation projects where accurate, code-compliant heating control is required.

Key Features

  • Pole Configuration: 1-Pole switching design delivers straightforward single-circuit control, simplifying installation for standard heating circuits.
  • Voltage Rating: Rated for 120-277V AC operation, giving installers flexibility to match the thermostat to the line voltage present at the heating circuit.
  • Amperage Rating: 22A capacity is built to accommodate the higher current draw of electric baseboard and wall heaters without exceeding rated performance.
  • Finish Options: Available in Navajo White and Northern White, allowing the thermostat to blend with common wall and trim colors without changing its electrical performance.
  • Series Identity: Carries the Q-Mark TA1A model designation from Marley, a name associated with electric heating control components.
  • Line-Voltage Control: Designed specifically for line-voltage heating applications rather than low-voltage control systems, simplifying wiring for direct heater connections.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Electric Baseboard Heating Systems
  • Wall-Mounted Convection and Fan Heaters
  • Commercial and Residential Heating Circuits
  • Line-Voltage Heating Installations
  • Renovation and Retrofit Heating Upgrades
  • New Construction Electrical Heating Wiring

Marley TA1AW – Frequently Asked Questions

1) What does 1-pole mean on the TA1A, and does it fully disconnect the heater?
One pole means it breaks a single leg of the circuit. On a 240V heater that leaves the other leg energized at the heater even when the thermostat is off, so it is not a disconnect. Kill the breaker before servicing. If your job or inspector requires both legs broken at the thermostat, you need a 2-pole line-voltage stat instead of the TA1A.
2) Is the TA1A a low-voltage thermostat I can use with a furnace or heat pump?
No. The TA1A is built for line-voltage resistive heating loads, baseboard and wall-mounted convection or fan heaters, wired directly at line potential. It is not a 24V control stat, so it does not belong on a furnace, air handler or heat pump control circuit.
3) What color options does the Marley Q-Mark TA1A come in, and are the electrical ratings the same?
Two finishes: Northern White (model TA1ANW) and Navajo White (model TA1AW). Electrically they are identical, both 1-pole, 120-277V AC, 22A. Pick whichever matches the existing trim or heater cabinets you are working around.
4) I manage apartments with old wall-mount heater thermostats. Can I standardize on the TA1A across units?
It is a reasonable standardization choice for line-voltage electric heat because the single 120-277V rating covers mixed 120V and 240V circuits across a building, and the 22A rating covers most single baseboard or wall heater circuits. The one thing to confirm unit by unit is pole count: the TA1A is 1-pole, so any opening currently switching both legs needs a 2-pole stat rather than this one.
5) Can the TA1A be used on a 277V commercial heating circuit?
Yes, 277V is the top of its range. The stat is rated 120-277V AC at 22A, which suits 277V commercial wall and baseboard heater circuits found in office and institutional buildings. Single-pole switching, so the circuit breaker remains the disconnecting means.
