Carrier 33ZCT59SPT Temp Sensor

The Carrier 33ZCT59SPT is a specialized digital space temperature sensor (T-59) engineered for seamless integration with Carrier Zoning systems and i-Vu Building Automation platforms. As a professional-grade 10K Ohm Type II thermistor, this wall-mount unit provides high-accuracy room temperature monitoring while offering on-board occupancy override and setpoint adjustment. The integrated custom LCD display provides clear visibility of current space conditions and setpoint offsets, allowing for precise environmental control in commercial or high-end residential applications.

Operating on 24VAC power at 2VA, the 33ZCT59SPT eliminates the need for frequent drift calibrations typical of legacy sensors. It features field-programmable options, including temperature display in °F or °C, setpoint display range, and security lockouts to prevent unauthorized local adjustments. This Carrier space temperature sensor is a drop-in HVAC replacement part designed for airside, packaged indoor/outdoor, and split systems utilize Carrier Comfort Network (CCN) or Linkage-compatible air sources. The low-profile beige housing and labeled screw terminals ensure a clean, efficient installation for technicians in the field.

Key Benefits:

• Integrated push-button override allows tenants to manually signal occupancy for heating or cooling outside of scheduled hours.
• High-precision 10K Type II thermistor ensures accurate feedback to the zone controller, reducing maintenance calls related to temperature drift.
• Adjustable setpoint offset enables localized user comfort without compromising system-wide efficiency or master programming.
• Digital LCD display provides real-time diagnostics and status of the current zone temperature and setpoint values.
• Rugged industrial construction and wall-mount design provide a durable interface for high-traffic commercial environments.

Common Questions:

Is this sensor compatible with non-Carrier systems?
This part is specifically optimized for Carrier Zoning systems, i-Vu, and CCN-compatible controllers. While it uses a standard 10K Type II thermistor, the digital display and override logic are proprietary to Carrier control sequences.

How do I toggle the display between Fahrenheit and Celsius?
The 33ZCT59SPT features field-programmable local settings that can be adjusted through the interface to show temperature in either metric or imperial units.

What wiring is required for this digital sensor?
The unit connects via standard HVAC control wiring to labeled screw terminals, typically requiring 24VAC power and communication lines back to the zone controller or air terminal PIC.
