| The PA404B is used with suspension-type unit heaters to make the fan circuit when a pressure rise indicates the presence of steam |
| Each model contains an SPST microns switch snap acting switch |
| Sensitive pressure actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch |
| A screw on top of the case allows set point adjustments without removing the cover |
| Differential is adjusted by means of a dial located inside the case |
