Maxitrol TD214B Selector Switch

The Maxitrol TD214B is a high-performance dual remote temperature selector engineered for direct-fired make-up air systems. Designed for industrial and commercial heating processes, this selector allows for seamless switching between two critical temperature ranges: a lower range of 55°F to 90°F (typically for spray mode or standard environmental control) and a higher range of 120°F to 170°F (optimized for bake mode or dry cycles). This Selectra Series 14 component works in tandem with an electronic modulator or modulator-regulator valve to provide instantaneous gas flow adjustments, replacing the need for outdated mod motors and butterfly valves.

For correct field operation, the TD214B selector switch must be paired with a TS214 discharge air sensor that matches these specific temperature spans. Integrating this unit into your control cabinet ensures precise, repeatable discharge air temperatures, which is vital for applications like paint spray booths and high-capacity door heaters. This selector is compatible with Selectra A1014 amplifiers and supports systems using natural, manufactured, mixed, or LP gases.

Key Benefits:

• Dual-Range Versatility: Eliminates the need for multiple controllers by offering dedicated 55-90°F and 120-170°F settings in one unit.
• Precision Modulation: Facilitates stable gas-fired temperatures with minimal hysteresis compared to mechanical linkages.
• Application Targeted: Specifically built for paint booths requiring alternating spray and dry temperature profiles.
• System Compatibility: Designed for standard Maxitrol Selectra Series 14 and Series 44 gas atmospheric systems.
• Durable Construction: Reliable toggle switch for manual range selection in demanding mechanical environments.

Common Questions:

• Can I use any discharge air sensor with the TD214B? No, the Maxitrol TD214B must be matched with a sensor, such as the TS214, that shares the exact same dual temperature ranges to maintain calibration.
• Is this compatible with 24VAC systems? Yes, this selector is designed to integrate with Selectra amplifiers powered by a 24VAC Class II transformer.
• Where should the remote selector be mounted? It should be installed in a protected control cabinet or a location away from direct weather and contaminated atmospheres to protect the internal circuitry.
