Overview: The Hog Slat Negative Pressure Ventilation Controller utilizes a Photohelic ® Pressure Switch and gage combination measuring the differential pressure of two monitoring tubes. The gage incorporates an easy to read display and easily adjustable High and Low pressure set point indicators by two control knobs on the front of the unit. The make/break dead band range is the width of a pointer which is sufficient to prevent short cycling operation. The controller is designed to open and close vents as required to maintain house static pressure within the defined range set by the two high and low limit pointers. The controller has onboard relays for direct connection to vent machines to open and close vents in order to regulate the pressure inside the room. Front panel switches provide local control to manually open and close vents.
