Panasonic SelectCycler Range Hood Pressure Sensor

Panasonic's range hood pressure sense is a unique low cost kitchen range hood pressure sensor works exclusively with the SelectCycler System to solve depressurization issues by allowing make up air to enter as soon as the range hood is turned on. The mechanism begins when the kitchen range hood comes on, creating positive pressure in range hood exhaust duct. The range hood pressure switch senses positive pressure from pressure tap and closes, sending power to damper to open. Lastly, the supply damper opens and the negative air pressure in the house brings in fresh air from outside to the HVAC/AHU return plenum.
