Description
The Nordyne 1016292R Pressure Switch is a safety part that is installed in different HVAC systems, and mainly in gas furnaces. This switch is used to measure pressure differentials of the furnace system to prevent dangerous and inefficient operations. Indeed, it quantifies the pressure differential, most often, across the combustion air intake and the venting system. The numbers 0.85/0.35 are the set points of the pressure switch in inches of water column in. w.c. The 0.85 in. w.c. value is the point at which the switch goes off, and this is an assurance that there is sufficient draft or airflow for safe combustion.
