Description
The Schneider Electric (Barber Colman) TC-2931 is a strap-on style changeover thermostat engineered for reliable Summer/Winter switching in hydronic HVAC systems. Designed to sense pipe temperature directly through its strap-on mounting, this thermostat automatically signals the system to switch between heating and cooling modes based on the temperature of the supply water — eliminating manual changeover and reducing the risk of system errors.
Key Features
- Strap-on mounting style for direct pipe-surface temperature sensing
- Summer/Winter automatic changeover operation
- Approximately 75°F fixed setpoint for reliable mode switching
- Approximately 15°F differential to prevent short-cycling
- 90°F minimum hot water temperature threshold for heating mode activation
- 60°F maximum chilled water temperature threshold for cooling mode activation
- Compact, field-ready design for straightforward installation on supply piping
Application
The TC-2931 is ideal for two-pipe fan coil systems, unit ventilators, and other hydronic applications where automatic Summer/Winter changeover is required. By strapping directly onto the supply pipe, it accurately reads water temperature and signals downstream controls to switch between heating and cooling, ensuring occupant comfort and system efficiency without manual intervention.
