Copeland Comfort Control (White Rodgers) 756-50 Thermostat

The White Rodgers 756-50 is a heavy-duty, surface-mount electric water heater thermostat and high-limit control designed for precision sensing in commercial and residential heating applications. This SPDT (Single Pole Double Throw) control operates as a universal replacement for upper combination units, featuring a primary temperature regulation range of 90°F to 150°F and a fixed high-limit safety cut-off at 170°F. Engineered for high electrical capacity, the Copeland 756-50 utilizes a snap-action contact mechanism to ensure clean switching and prevent arcing in demanding environments.

As a veteran-grade water heater limit switch, this unit offers a 17°F to 27°F differential, providing stable cycling and protecting the tank from overheating. The manual reset limit ensures that if the system exceeds safe operating temperatures, the circuit remains open until a technician inspects the system, maintaining strict safety protocols. Designed for field-service efficiency, the 756-50 thermostat is compatible with 120V to 480V circuits, making it a versatile stock item for contractors servicing various dual-element tank configurations.

Key Benefits:

• Universal Compatibility: Simplified service calls by replacing most upper element thermostats and limit controls in standard electric water heaters.
• Snap-Action Contacts: Built with high-grade materials to provide a rapid, reliable break in the circuit, extending the life of the control.
• Integrated Safety: Combines temperature regulation and a manual reset high-limit control in a single, compact surface-mount housing.
• Industrial Voltage Rating: Rated for high-capacity applications across 120V, 240V, and 480V systems.
• Adjustable Calibration: Allows for dial-in accuracy between 90°F and 150°F to meet specific user demands while prioritizing safety.

Common Questions:

What is the difference between an SPST and this SPDT model?
The SPDT (Single Pole Double Throw) design of the 756-50 allows it to switch power between components—typically used in upper element positions to divert power to the lower element once the top of the tank reaches the set temperature.

Can this be used on a single-element water heater?
While typically used in two-element systems to manage the heating sequence, it can be applied as a limit and control in various heating setups provided the mounting surface and electrical ratings match.

Is the high-limit reset automatic?
No, the 170°F high-limit is a manual reset. This is a deliberate safety feature that requires a physical reset after a trip to ensure the cause of the overheat is addressed by a professional.
