The Rheem Pressure Switch is a protective device that opens and causes the HVAC system to stop operating under certain conditions which may be harmful. It is important to note that when a pressure switch is replaced, it is replaced with the exact switch. The Pressure settings are very delicate and any change in the setting by installing a different switch could cause a safety issue.
