Copeland 1f57-306 Multi-stage Low Voltage Thermostat

Product Description

The COPELAND 1f57-306 is a multi-stage, low-voltage thermostat designed for residential and light commercial HVAC systems that require two stages of heating and two stages of cooling. It operates on low-voltage control wiring, making it compatible with conventional forced-air systems controlled by a standard 24-volt thermostat circuit. The beige finish suits typical residential wall installations. Licensed HVAC technicians install this thermostat as part of a staged system setup where single-stage control is not sufficient to meet comfort or equipment requirements.

This thermostat is suited for 2-heat/2-cool staged HVAC applications, including systems with a primary and secondary heating source or dual-stage compressor cooling. It is intended for forced-air systems that use low-voltage control wiring and require a thermostat capable of managing multi-stage call sequencing. Typical installations include residential split systems and light commercial applications where staged temperature control improves efficiency and comfort.

Key Features

• 2-stage heating and 2-stage cooling control for multi-stage HVAC systems
• Low-voltage operation compatible with standard 24-volt thermostat wiring
• Beige housing finish suited for standard residential wall mounting
• Designed for forced-air systems requiring staged call sequencing

Compatibility

Designed as an OEM-style replacement for multi-stage low-voltage thermostat applications in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local codes and the equipment manufacturer guidelines. Disconnect power to the HVAC system at the breaker before removing the existing thermostat or making any wiring connections. Verify that the system control board supports 2-stage heating and 2-stage cooling inputs before installing this thermostat. Follow NEC requirements for low-voltage thermostat wiring and secure all connections before restoring power.
