Description
The Carrier 33ZCT56SPT is a precision-engineered space temperature sensor designed for commercial HVAC systems. This wall-mounted sensor provides reliable temperature readings, allows for occupant override, and offers a built-in setpoint adjustment — all in a sleek, low-profile design.
Key Features
- Accurate Temperature Sensing: Equipped with a 10 kΩ thermistor, this sensor delivers consistent and accurate room temperature measurements, helping maintain optimal heating and cooling performance.
- Override Functionality: The sensor’s push-button override allows occupants to temporarily override the programmed schedule of the HVAC system, giving control back to the user when needed.
- Setpoint Adjustment: An integral slide potentiometer enables adjustable temperature offsets, letting users fine-tune their heating and cooling setpoints within a configured range.
- Durable, Low-Maintenance Design: Built without delicate moving parts, the sensor eliminates the drift and calibration issues common with traditional thermostats, reducing long-term maintenance costs.
- Sleek & Discreet: Beige housing, compact dimensions (4.51″ H × 2.75″ W × 1.15″ D), and a minimalist profile make this sensor blend seamlessly into any interior décor.
- Wide Operating Range: Designed to operate in environments from 32 °F to 120 °F (0 °C to 49 °C) with up to 95% non-condensing humidity.
