Copeland Comfort Control (White Rodgers) 01G65-641 Thermostat

The Copeland Comfort Control (White Rodgers) 01G65-641 Thermostat is a heavy-duty line voltage heating thermostat engineered for precise control of baseboard electric heat, radiant cable heat, and fan-forced resistance systems. As a direct replacement for 1A65W-641 and 1A65-641, this mechanical bimetal unit provides a rugged, mercury-free solution for contractors requiring high-amperage switching without the complexity of digital interfaces. Designed for vertical mounting on a standard 2x4 electrical box, it features a single-pole single-throw (SPST) switch action that opens on temperature rise, supporting 22A resistive loads at 120V or 240V and up to 18A at 277V. The broad 40°F to 85°F temperature range ensures versatility across residential and light commercial environments, maintaining consistent setpoints via a reliable bimetal sensing element. This non-programmable mechanical thermostat eliminates common failures associated with electronic components in high-voltage applications, providing a "set and forget" interface for zones where manual operation is ideal.

Key Benefits:

• Universal Compatibility: Serves as the official direct replacement for 1A65-641 and 1A65W-641 models, ensuring a seamless retrofit without structural modifications.
• High Capacity Switching: Rated for up to 5000 Watts at 240V, making it suitable for high-wattage baseboard and glass panel heating units.
• Rugged Bimetal Construction: Utilizes a mechanical sensor for long-term operational stability in demanding environments.
• Simplified Installation: Includes essential wallplate hardware for rapid mounting on standard junction boxes.
• Wide Operating Range: Covers a 40-85°F setpoint range, perfect for frost protection in garages or high-comfort residential zones.

Common Questions:

Is the 01G65-641 a double-pole or single-pole thermostat?
This is a single-pole (SPST) model. It breaks one side of the power line. For applications requiring a double-pole disconnect that breaks both sides of the line, technicians should specify the 1G66 series.

Can this thermostat control a 277V circuit?
Yes, it is rated for line voltage application at 120V, 240V, and 277V. Note that the resistive amperage rating adjusts to 18A when utilized on 277V systems.

Does this unit require a neutral wire or batteries?
No, as a mechanical bimetal thermostat, it operates entirely on line voltage and does not require batteries or a common/neutral wire for logic power.
