Kele Product ST-S3E-XME Stat

The Kele ST-S3E-XME Executive Wall Stat is a high-precision 10k Type 3 thermistor designed for demanding Building Automation Systems (BAS) and commercial HVAC applications. Engineered for long-term stability and accuracy, this room temperature sensor features a 10,000Ω resistance output at 77°F (25°C), ensuring seamless integration with major controllers. The executive-style beige housing is vented to facilitate rapid thermal response while maintaining a professional aesthetic. Built for field reliability, the unit includes a membrane momentary override switch wired directly to the terminal block for easy contractor override and fan control signals. Its NEMA 1 enclosure and insulated backplate mitigate the impact of interior wall temperatures, providing a true representative reading of the occupied space. This rugged HVAC wall sensor is a preferred choice for schools, offices, and industrial facilities requiring a dependable room temperature sensor with a legacy of performance in the field.

• High-Accuracy Sensing: Optimized 10k-3 thermistor element provides a precise ±0.36°F (±0.2°C) accuracy.
• Durable Construction: Features a rugged poly housing and a tan metal faceplate for longevity in high-traffic areas.
• Efficient Installation: Includes a standard terminal block and universal mounting plate for direct wall or junction box attachment.
• Field Interface: Integrated momentary override switch allows for local setpoint adjustments or system wake-up.
• NTC Stability: Negative Temperature Coefficient (NTC) curve ensures consistent resistance values across a wide operating range.

Common Questions

Is the Kele ST-S3E-XME compatible with my existing BAS controller?
The ST-S3E-XME utilizes a standard 10k Ohm Type III thermistor curve. It is compatible with most HVAC automation platforms that accept a 10k-3 resistance input, including systems from Andover, Delta, and Schneider Electric.

Can this sensor be mounted on a standard electrical box?
Yes, the executive enclosure and wide backplate are designed to mount directly to a single-gang electrical box or directly to the wall surface using the included hardware.

Does this unit require an external power source?
No, as a passive resistance-based sensor, the ST-S3E-XME does not require an external power supply; it draws its signal directly from the controller's analog input loop.
