DTR

Built-in temperature controller, switching, with display

Application
The DTR is a single-stage temperature controller for installation in switch cabinets, as remote displays or remote controllers in refrigeration, airconditioning and process engineering. The switch hysteresis is adjustable to prevent short switching intervals. Visual and audible indicators (flashing display, indication of error code and warning signal) indicate abnormal switching states.
