Description
The Johnson Controls T26J-7 is a line voltage wall thermostat engineered specifically for cooling applications in commercial and residential HVAC systems. Designed as an energy conservation heating model, this thermostat enforces a minimum setpoint of 75°F, helping to prevent unnecessary overcooling and reduce energy waste in occupied spaces.
Featuring a straightforward knob adjustment interface, the T26J-7 eliminates complexity by omitting a thermometer display and selector switch — making it ideal for installations where simplified, tamper-resistant control is desired. The SPST (Single-Pole, Single-Throw) switching configuration provides reliable on/off control suited for single-stage cooling equipment.
With a 2-degree differential, this thermostat delivers consistent temperature control by minimizing short-cycling while maintaining occupant comfort. Its line voltage design allows for direct connection to line voltage cooling systems without the need for a separate transformer or low-voltage wiring.
