Maxitrol TS244A Temperature Sensor

The Maxitrol TS244A is a precision-engineered wall mount space temperature sensor specifically designed for integration with Series 44 Selectra electronic gas flame modulation systems. Built for the rigors of industrial and commercial space heating, this electronic temperature sensor maintains a specialized sensing range of 40-80 degrees F (4-27 degrees C). As a veteran tech knows, compatibility is paramount: the TS244A must be paired with a Selectrastat or temperature selector with an identical operating range to ensure accurate resistance feedback to the amplifier. This white, low-profile unit provides the critical ambient data necessary for the Selectra modulation system to adjust gas flow at the burner, ensuring stable environmental control in direct-fired equipment. The sensor’s 4500-ohm nominal resistance profile allows for seamless communication with Maxitrol amplifiers, enabling the linear modulation of M/MR valves. This is an essential component for any technician servicing high-performance make-up air units or industrial space heaters requiring high-accuracy HVAC climate control.

• Selectra Series 44 Compatibility: Optimized for use as a remote sensing element within Maxitrol Series 44 modulation circuits.
• Precision Sensing Range: Dedicated 40°F to 80°F range provides targeted accuracy for specialized industrial heating setpoints.
• Industrial Durability: Robust construction designed for long-term reliability in commercial boiler rooms and factory environments.
• Seamless Integration: Low-profile white wall-mount housing allows for unobtrusive installation in any heated space.
• Linear Modulation Performance: Delivers consistent resistance signals to the amplifier for smooth, flutter-free valve regulation.

Is the TS244A compatible with the 55-90°F series?
No. For the system to calibrate correctly, the sensor and the selector/amplifier must share the same temperature range. The Maxitrol TS244A is strictly for 40-80°F systems.

What are the wiring requirements for this sensor?
Control wiring should be run separately from power or ignition wires. If using shielded cable, ensure the shield is grounded only at the amplifier to prevent signal interference.

Can I use this sensor without an amplifier?
No, the TS244A is a passive sensing element designed to provide variable resistance to a Maxitrol Selectra amplifier; it cannot control a gas valve directly.
