Resideo AMX302T-LF Kit
The Carrier 33CS250-FS is a commercial-grade digital programmable thermostat designed for 24V constant volume HVAC systems. Engineered for 7-day, 5-2, or 24-hour scheduling, this dual setpoint thermostat provides precise temperature control for commercial heat pumps and rooftop units. It supports up to 2 stages of heating and 2 stages of cooling, making it a versatile choice for multi-stage applications. The unit features non-volatile memory to retain configuration settings during power outages and includes a large, backlit display for easy field programming. Field technicians will appreciate the proportional integral control which minimizes temperature swings by adjusting cycle rates based on the thermal load. This Carrier commercial thermostat also allows for remote sensing capabilities and occupancy-based setbacks to maximize system efficiency in demanding environments.
Key Benefits- Multi-Stage Compatibility: Configurable for 1H/1C or 2H/2C systems, including auxiliary heat control for heat pump cycles.
- Advanced Data Retention: Integrated EEPROM memory ensures your custom setpoints and schedules are preserved without battery backup requirements.
- Precise Comfort Control: Utilizes PI (Proportional-Integral) logic to prevent short-cycling and maintain tighter temperature tolerances.
- Commercial Durability: Robust hardware design specifically tailored for high-traffic commercial HVAC applications and rooftop unit operation.
Is the 33CS250-FS compatible with multi-stage heat pumps?
Yes, this unit is designed to handle 2-stage heating and 2-stage cooling configurations, including heat pumps with secondary heat strips.
Does this thermostat require a common wire (C-wire)?
This model typically operates on 24VAC commercial control circuits and requires a common wire connection for consistent operation and display backlighting.
Can I lock the keypad to prevent unauthorized adjustments?
The Carrier 33CS250-FS features keypad lockout functionality to ensure terminal settings and schedules remain tamper-proof in public spaces.
