Asco PG10A Limited Adjustable Deadband Pressure Switch Unit

The ASCO PG10A is a two-position, spring-return switch used in various HVAC equipment. It serves as a dependable and precise controller for alternating between two electrical circuits in response to variations in temperature or pressure. Because of the switch's limited deadband design, there is not much space between its on and off setpoints. This contributes to increased comfort, equipment protection, efficiency, and consistency in the HVAC system's pressure and temperature levels.  To put it another way, the ASCO PG10A operates similarly to an automated on-off switch for vital HVAC system parts like compressors and pumps. It keeps an eye on pre-set temperature or pressure limitations and, upon reaching them, initiates the activation or deactivation of these components. By reducing deadband, the limited deadband feature makes sure the system stays at constant levels.
