Copeland Comfort Control (White Rodgers) 1F83C-11PR Thermostat

The Copeland Comfort Control 1F83C-11PR is a professional-grade 80 Series single stage thermostat designed for high-reliability applications in residential and light commercial sectors. This unit serves as the direct replacement for 1F80-0471 and 1F80-240, providing seamless integration for legacy White Rodgers footprints. It supports 1 Heat/1 Cool conventional systems and 1 Heat/1 Cool heat pump systems, offering contractors a versatile solution for varied job site requirements. Powering options include a 20-30VAC hardwire connection or mV-30VAC battery power, ensuring compatibility with 24-volt and millivolt systems. Performance is managed through a configurable interface allowing for 7-day, 5+1+1 day, or non-programmable operation with up to four periods per day. To prevent unauthorized setpoint adjustments in high-traffic or rental environments, the 1F83C-11PR includes a robust keypad lockout feature and a precise temperature setpoint range of 45°F to 99°F.

• Universal Compatibility: Operates on 24V or millivolt systems, making it a "truck stock" essential for 1H/1C HVAC systems.
• Advanced Programming: Field-selectable 7-day, 5+1+1 day, or non-programmable modes to match specific occupant needs.
• Variable Differentials: Includes adjustable cycle rate settings (Fast, Medium, Slow) to optimize equipment run times and prevent short-cycling.
• Dual Power Flexibility: Reliable operation via C-wire hardwiring or dual-battery backup for installations where a common wire is unavailable.
• Tamper Prevention: Integrated keypad lockout secures thermal profiles in commercial or multi-family housing.

Is the 1F83C-11PR compatible with multi-stage heat pumps?
No, this model is specifically engineered for single-stage 1H/1C conventional or single-stage heat pump systems without auxiliary heat. For multi-stage applications, an 80 Series multi-stage model is required.

Does this thermostat require a C-wire?
This unit is dual-powered. While a 24V hardwire connection is recommended for maintenance-free operation, it can function entirely on battery power (mV-30VAC) for older 2-wire or 3-wire systems.

What are the dimensions for wall coverage?
The 1F83C-11PR measures 3-3/4" H x 6" W x 1-1/8" D, providing a wide profile that often covers the footprint of older mechanical or digital thermostats without the need for a wall plate.
