Series Description
The Model T775 single- or multi-loop standalone controller is a standalone multi-point and multi-loop controller designed for a wide range of applications. The I/O point mix is unit-specific with temperature, humidity, and pressure input models available. Relay or analog output models may be selected as well. Single-loop, two-loop, and reset controllers may be selected, all including a seven-day time clock for output disable or night setback. The relay output controllers have adjustable differential control algorithms. Analog output controllers have adjustable throttling range; proportional plus integral (PI); or proportional, integral, and derivative (PID) control. The backlit display is easy to read, and the menu-driven setup is simple. The T775 is available in NEMA 1 or NEMA 4X enclosures for the most demanding environments.
