Rheem-Ruud 42-102056-03 Dual Pressure Switch

The Rheem-Ruud 42-102056-03 Dual Pressure Switch is an essentialaccessory on the HVAC systems and it is used to control the system pressure. This pressure performance implies that the system being monitored is able to sense both high and low pressure conditions. It can operate at high pressures of up to 1. 2” WC for water closet and a low pressure rating of 0.86” WC, thereby delivering optimal performance. It works through the initiation of certain operations like turning off or on some parts of the system when the pressure levels reach certain levels in order to avoid hazardous situations. This feature increases safety and effectiveness in the functioning of HVAC systems.
