The Maxitrol TD114F Temperature Selector is a critical component for Selectra Series 14 systems, specifically engineered for make-up air heating in direct-fired equipment. As a remote discharge air temperature selector, the TD114F provides a precise control range of 40° to 80°F, making it the standard choice for facilities requiring lower setpoint thresholds and consistent electronic gas flame modulation. This selector is designed to interface seamlessly with Maxitrol amplifiers and must be paired with a matching TS114F discharge air sensor to ensure system calibration and prevent temperature droop. For veteran technicians, the TD114F offers a built-in override feature, allowing a 0° to 40°F increase over the 40°F setpoint when integrated with a room override thermostat. This ensures adaptable climate control in industrial settings like paint booths or warehouses. The unit’s 10,000? resistance at 77°F provides the high-accuracy signal needed for the modulating valve to maintain stable discharge temperatures. Its compact design allows for easy field installation in control cabinets, provided the wiring runs remain under 200 feet to maintain signal integrity without the need for additional signal conditioners. Key Benefits: Precise Modulation: Enables exact discharge air temperature control within the 40-80°F range for direct fired equipment. System Compatibility: Fully compatible with Selectra Series 14 components, including A1014 amplifiers and MR/M modulating valves. Operational Flexibility: Includes an override capability of 0-40°F to handle fluctuating space heating demands. Durable Industrial Build: Solid-state construction designed to withstand the rigors of mechanical rooms and industrial control cabinets. Optimized HVAC Performance: Ensures consistent make-up air delivery, reducing energy waste and improving indoor air quality. Common Questions: Can I use the TD114F with any TS114 sensor? No, technical specifications require that the suffix letters match. The TD114F must be used with a TS114F sensor to ensure the resistance ranges align for proper calibration. What is the maximum wiring distance for this selector? For standard installations, wiring should not exceed 200 feet. For longer runs, we recommend utilizing an ES261-1/ES261-2 two-piece version to prevent signal loss. Does this unit support room override? Yes, when wired into a Series 14 system with a room thermostat, it can provide space temperature control by raising the discharge air temperature above the 40°F setpoint.
