Honeywell T775B2016 -40/248F Temperature Control R,2Spdtnema4X

The Honeywell T775B2016 is a two-stage, single-pole, double-throw (SPDT) temperature control relay that is used in a variety of HVAC (heating, ventilation, and air conditioning) systems. It functions by utilizing temperature variations to turn on and off electrical circuits. The relay can control temperature in a variety of applications to its -40°F to 248°F programmable operating range. The relay triggers linked equipment, like compressors or heating elements, to maintain the desired temperature when the temperature rises above the set point. In contrast, the relay deactivates to stop the equipment from overheating or cooling down when the temperature drops below the predetermined point. The HVAC systems' effective and reliable temperature management is guaranteed by this technique.
