Description
The Schneider Electric (Barber Colman) TK-5101 is a pneumatic one-pipe room thermostat engineered for reliable temperature control in commercial and institutional HVAC applications. Designed with a reverse-acting control action, this thermostat is ideal for systems where an increase in room temperature requires a decrease in branch line pressure — commonly used in heating systems with normally open valves or cooling systems with normally closed valves.
Key Features
- Pneumatic one-pipe design — uses a single air supply line for both supply and branch signal
- Reverse-acting (RA) control action for compatibility with appropriate valve and damper configurations
- 55–85°F (13–29°C) dial temperature range for precise room comfort setpoint adjustment
- Includes protective cover and inserts for a clean, finished wall installation
- Compact, low-profile housing suitable for standard wall mounting
- Designed as a direct replacement for legacy Barber Colman TK-5101 thermostats
Application
The TK-5101 is well-suited for commercial buildings, schools, hospitals, and other facilities utilizing pneumatic control systems. Its reverse-acting operation makes it an excellent choice for hot water heating coils with normally open valves, where zone temperature comfort and energy efficiency are priorities. The included cover and inserts provide a professional, tamper-resistant finish on the wall.
