Daikin-McQuay 111048101 Sensor

The Daikin-McQuay 111048101 Temperature Sensor is a precision HVAC thermistor designed for integration with MicroTech and Open Choices control systems. This wall-mounted space sensor provides accurate ambient temperature monitoring and features a manual override button, allowing field technicians to force the unit into occupied mode during off-schedule maintenance or testing. Engineered for high stability and low drift, the 111048101 ensures the building automation system (BAS) receives reliable terminal equipment feedback. Resistance values are calibrated specifically for McQuay legacy units and modern Daikin controllers, making it a critical replacement HVAC sensor for maintaining setpoint accuracy. Its low-profile housing and standard two-wire or three-wire terminal connections simplify installation for contractors managing large-scale commercial air conditioning or heating applications. By utilizing this 10k-2 thermistor equivalent, you ensure seamless HVAC communication and prevent short-cycling or incorrect cooling loads caused by faulty environmental sensing.

• Precise Signal Output: Delivers accurate resistance-to-temperature conversion for precise HVAC zone control.
• Manual Override Function: Simplifies troubleshooting by allowing manual occupancy bypassing directly at the sensor.
• Daikin-McQuay Compatibility: Direct fit for MicroTech II and III units, ensuring no-guesswork integration.
• Rugged Construction: Built to withstand commercial environments while maintaining a professional aesthetic.
• Simplified Wiring: Features clearly labeled terminals to reduce commissioning time on the job site.

What is the typical resistance value for the 111048101 sensor?
This sensor typically operates as a 10k-2 Ohm Type II thermistor, though resistance curves should be verified against the specific Daikin MicroTech controller scaling.

Can this sensor be used with non-Daikin controllers?
While designed for Daikin-McQuay systems, it may be compatible with other building management systems (BMS) that support the same thermistor curve and override signaling logic.

Does the override button provide a momentary or maintained signal?
The override is generally a momentary contact closure that triggers the controller's internal timer for occupancy duration.
