Schneider Electric (Barber Colman) TK-1801 Pneumatic Zero Energy Band Room Thermostat

Description

The Schneider Electric (Barber Colman) TK-1801 is a pneumatic zero energy band room thermostat engineered for precise, energy-efficient climate control in commercial and institutional HVAC applications. Designed for normally open heat, direct acting operation, this thermostat delivers reliable proportional control in 2-pipe pneumatic systems while minimizing unnecessary heating and cooling energy consumption through its adjustable zero energy band feature.

Zero Energy Band Technology

The TK-1801 incorporates an adjustable zero energy band that suspends heating and cooling output when space conditions fall within an acceptable comfort range. This dead-band approach reduces system cycling and lowers energy costs — a key advantage in commercial building environments where occupancy and load conditions vary throughout the day.
