Maxitrol TD294E-609-0818 Temperature Selector

The Maxitrol TD294E-609-0818 is a specialized dual remote temperature selector engineered for the Selectra Series 94 modulation systems. This controller is the industry standard for direct-fired burners and make-up air units, specifically where distinct operating phases are required. It features two independent adjustment dials: a low-range 60° to 90°F scale and a high-range 80° to 180°F scale. This configuration is critical for paint spray booth applications, allowing technicians to switch seamlessly between "spray" (ambient comfort) and "dry" (high-heat curing) cycles using an external SPST switch.

Designed for reliability in industrial environments, the Maxitrol TD294E-609-0818 utilizes an LED digital display for real-time monitoring of discharge air temperatures. It integrates directly with the A1494 amplifier and is typically paired with the TS194Q quick-response sensor to maintain precise discharge air targets. By utilizing electronic modulation rather than traditional butterfly valves, this selector ensures stable gas flow and instantaneous response to load changes, maximizing combustion efficiency in industrial HVAC systems.

• Dual-Range Versatility: Provides dual scales of 60-90°F and 80-180°F, specifically optimized for paint booth "spray/dry" transitions.
• Selectra Series 94 Compatibility: Seamlessly interfaces with Maxitrol amplifiers and modulator-regulator valves for precise electronic gas modulation.
• Enhanced Monitoring: Features a clear LED digital readout for immediate verification of sensed temperatures.
• Contractor-Grade Durability: Built for high-capacity systems up to 30,000,000 BTU/h, ensuring long-term stability in process heating environments.
• Simplified Control Logic: Facilitates remote temperature adjustment without needing access to the main burner manifold or amplifier cabinet.

What sensors are compatible with this dual selector?
The TD294E-609-0818 is typically paired with the Maxitrol TS194 series sensors. For the most accurate performance in fluctuating airflows, the TS194Q quick-response sensor is recommended.

Can this selector be used with Series 14 systems?
This specific model is designed for Series 94. While Series 14 uses similar logic, always verify your amplifier model—such as the A1494—to ensure proper voltage and signal communication.

How do I switch between the two temperature ranges?
Range switching is accomplished via a remote SPST (Single Pole Single Throw) switch. This allows the operator to toggle between the 60-90°F pot and the 80-180°F pot based on the current process requirement.
