The negative pressure sensor measures the current negative pressure value at the end of the connected pressure measuring hose. The digital climate controller receives the negative pressure values and regulates the speed of the intake fan to maintain the negative pressure at the desired value.
The negative pressure sensor is connected to the controller using the 5m cable with RJ45 connector. The blue hose labeled "Inside" on the sensor is connected to the supplied hose, which is routed into the box or room where the negative pressure is to be controlled.
When the sensor is located in the room where the negative pressure is to be controlled, the long hose is connected to the black hose on the sensor labeled "Outside" and led outside.
