Maxitrol T244A Selectra Stat

The Maxitrol T244A Selectra Stat is a precision electronic temperature sensor designed for wall mount installation in commercial and industrial HVACR heating systems. Operating within a 40-80 degrees F temperature range, this modulating space sensor provides high-accuracy resistance signals to the Selectra amplifier, ensuring stable discharge air temperatures. The T244A is a critical component for maintaining consistent thermal environments in large facilities, functioning as a remote setpoint and sensing unit. Built with durable housing and high-quality internal thermistors, it prevents rapid cycling and maximizes the efficiency of indirect fired heaters. Its low-voltage wiring configuration allows for seamless integration into existing Maxitrol modulation systems, making it a reliable choice for field replacements or new system commissions where precise room temperature control is non-negotiable for operational performance.

• Precise Modulation: Provides accurate feedback to the amplifier for smooth burner firing rates and energy efficiency.
• Wide Temperature Range: The 40-80°F setpoint range is optimized for industrial comfort and process heating requirements.
• Durable Construction: Engineered for longevity in demanding mechanical environments, reducing the need for frequent recalibration.
• Simplified Wiring: Designed for straightforward low-voltage connection to Selectra control systems.
• Wall Mount Design: Ensures proper airflow over the sensing element for representative room temperature readings.

Is the Maxitrol T244A compatible with all Selectra systems?
The T244A is specifically designed for use with compatible Selectra amplifiers and series controls. Always verify lead wire resistance and amplifier series numbers to ensure system matching.

How does the T244A differ from a standard 24V thermostat?
Unlike a standard on/off thermostat, the T244A is a modulating electronic sensor that provides a variable signal to adjust burner output proportionally, rather than simply cycling the unit on and off.

Where is the optimal placement for this sensor?
For accurate readings, mount the T244A approximately five feet above the floor on an interior wall away from drafts, direct sunlight, or supply air registers.
