Maxitrol TD244P Temperature Selector

The Maxitrol TD244P is a high-precision panel mount temperature selector engineered specifically for Selectra Series 44 systems. Designed for direct-fired space heating applications, this 55-90 degrees F selector allows technicians to set a specific target temperature that the amplifier uses to modulate the gas flow via electronic modulator-regulator valves. Unlike general wall-mounted units, the TD244P is optimized for integration into control cabinets, providing a streamlined interface for industrial HVACR systems. To ensure accurate modulation control, it is critical that the selector is paired with a TS244 space temperature sensor that shares the identical 55°F to 90°F range. This component is essential for maintaining stable discharge air temperatures and preventing the rapid cycling often associated with standard mechanical thermostats. When performing a field replacement or new HVAC control installation, verify that your A1044 amplifier is properly calibrated to the base resistance of this unit to ensure seamless gas flame modulation and energy-efficient burner operation.

• Optimized for Series 44: Specifically designed to work with Maxitrol Selectra modulating gas valves and amplifiers.
• Broad Temperature Range: Precise 55-90 degrees F control range suitable for commercial warehouses and industrial facilities.
• Panel Mount Configuration: Compact footprint allows for professional installation within centralized HVAC control panels.
• Enhanced Reliability: Solid-state components provide instantaneous response to temperature fluctuations without the wear of moving parts.
• System Compatibility: Seamlessly replaces legacy TD244 models when panel mounting is required for updated equipment specs.

Is the TD244P compatible with all Maxitrol sensors?
No, for proper electronic modulation, the TD244P must be paired with a sensor from the same thermal range, such as the TS244 space sensor. Using a mismatched sensor range will lead to incorrect resistance signals and poor burner performance.

What is the difference between the TD244 and the TD244P?
The "P" suffix indicates a panel mount design. While the internal temperature selector logic is the same, the TD244 is meant for surface wall mounting, whereas the TD244P is built to be integrated into an equipment control enclosure.

Does this unit require 24V AC power?
The selector itself is a resistive component that interfaces with the Selectra amplifier. Although the amplifier requires a 24V AC transformer, the TD244P receives its signal requirements directly through the low-voltage wiring circuit from the amplifier terminals.
