Maxitrol TD244AP Temperature Selector

For contractors servicing direct-fired heating equipment, the Maxitrol TD244AP is a critical component for maintaining precise space temperature control. This panel mount temperature selector is engineered for the Selectra Series 44 system, providing a setpoint range of 40-80 degrees F. As a veteran-grade remote temperature selector, the TD244AP functions by sending a resistance-based signal to the Maxitrol amplifier, which then modulates the gas flow through an M or MR series valve. When replacing a Selectrastat or integrating into a custom control cabinet, ensuring that your TD244AP selector and the TS244A space temperature sensor share the same temperature range is non-negotiable for system compatibility. This industrial-grade modulating gas control part eliminates the common drift found in mechanical thermostats, offering the precise HVAC temperature regulation required in commercial and industrial direct fired heaters. Its compact panel mount design allows for clean, centralized installation within high-performance heating lineups.

Key Benefits

• System Compatibility: Specifically designed for seamless integration with Maxitrol Selectra Series 44 electronic gas flame modulation.
• Operational Range: Supports a 40 to 80 degree Fahrenheit setpoint, ideal for specialized space heating environments.
• Technical Precision: Facilitates instantaneous gas flow adjustment to maintain stable ambient temperatures without the cycling losses of standard controls.
• Mounting Versatility: The panel mount configuration allows for professional installation directly into equipment control boards or remote monitoring stations.

Common Questions

How do I verify if the TD244AP is compatible with my existing sensor?
Technical specifications dictate that the selector and the sensor must have an identical temperature range. For the TD244AP (40-80°F), you must use the TS244A sensor to ensure accurate resistance feedback to the amplifier.

Can this selector be used to replace a wall-mounted Selectrastat?
Yes, the TD244AP is frequently used as a remote temperature selector to replace the integral selector of a Selectrastat, provided it is paired with a standalone space temperature sensor.

What wiring precautions should be taken during installation?
Control wires for the Maxitrol TD244AP must never be run in the same conduit as power or ignition wires. High-voltage interference can cause erratic modulation or terminal damage to the electronic amplifier.
