The Maxitrol TD114 Temperature Selector is a professional-grade remote temperature selector designed specifically for integration with Selectra Series 14 modulation systems. This HVAC discharge air control device allows for precise adjustment of a gas-fired unit’s output, maintaining a steady temperature range of 55°F to 90°F. Engineered for industrial and commercial make-up air units, the TD114 provides superior responsiveness compared to traditional mod motors or butterfly valves by sending instantaneous signals to the amplifier for immediate burner adjustment. A critical feature of this model is the integrated 0-40°F override, which allows the system to temporarily exceed the set point when the room override thermostat is activated, ensuring rapid recovery in makeup air heating applications. For optimal performance, this direct-fired gas control part must be matched with the corresponding TS114 sensor to ensure signal compatibility and electronic modulation accuracy. Key Benefits Precise Modulation: Facilitates stable air temperatures by providing constant feedback to the Selectra amplifier, eliminating large temperature swings common in non-modulating systems. Flexible Temperature Control: The primary 55°F to 90°F dial range is complemented by a 0° to 40°F override capability for high-demand recovery periods. Remote Accessibility: Designed for mounting in control cabinets or accessible operator stations, allowing for set point changes without accessing the main HVAC unit. OEM Compatibility: Specifically calibrated for use with Maxitrol Series 14 amplifiers and TS114 discharge air sensors for seamless plug-and-play installation. Energy Efficiency: By maintaining a tight discharge air temperature, the unit prevents fuel waste associated with overheating and cycling. Common Questions What components are required for a complete control loop? To function properly, the Maxitrol TD114 requires a compatible Series 14 amplifier (such as the A1014), a TS114 discharge air sensor, and a Selectra modulator or modulator-regulator valve. Can I use a TS114A sensor with this TD114 selector? No. Suffix letters must match to ensure the resistance ranges align. A Maxitrol TD114 (55-90°F) must be paired with a TS114 sensor of the same range for correct calibration. How do I handle wiring runs exceeding 200 feet? For extremely long wire runs, the TD114 should be replaced with the ES261 series, which uses a two-piece configuration to maintain signal integrity over distance.
