Maxitrol TD244 Temperature Selector

The Maxitrol TD244 is a professional-grade wall mount space temperature selector engineered for precise atmospheric control within Selectra Series 44 modulation systems. Designed for direct-fired make-up air and space heating applications, this remote temperature selector allows technicians to set and maintain environmental conditions between 55°F and 90°F. It functions by sending a resistive signal to a compatible A1044R amplifier, which in turn modulates the gas flow through M411, M511, or M611 series valves to match the thermal load of the building.

Built for durability in commercial environments, the Maxitrol TD244 features a standard vertical wall mount configuration, measuring approximately 4.5" x 2.56". For optimal performance, the unit should be installed in a location reflecting the average ambient temperature, away from localized drafts or heat sources. When troubleshooting the Series 44 system, technicians should verify that the selector resistance measures approximately 2100 ohms to ensure proper communication with the modulation amplifier and accurate electronic gas modulation.

• Compatible with the high-performance Selectra Series 44 for seamless direct-fired heater control.
• Wide 55-90 degree F setpoint range provides flexibility for various industrial and commercial space heating needs.
• Wall mount design ensures easy integration into standard HVAC control layouts.
• Provides precise feedback to the electronic modulation amplifier to prevent temperature overshooting.
• Robust construction minimizes drift, ensuring long-term setpoint stability for contractors and facility managers.

What amplifier is compatible with the Maxitrol TD244?
The TD244 is specifically designed to operate with the Maxitrol A1044 series amplifiers, such as the A1044R or A1044U, as part of a complete Selectra Series 44 system.

Can I use the TD244 with a 40-80°F system?
No, the Maxitrol TD244 is calibrated for the 55-90°F range. For the 40-80°F range, the TD244A model is required to ensure sensor-amplifier compatibility.

How should the wiring be run for the TD244?
To prevent erratic operation, control wiring for the space temperature selector must be run in a separate conduit from high-voltage power or ignition lines. Using shielded, twisted-pair wiring is recommended for long runs.
