Outdoor Pressure Sensor: Mount the Outdoor Pressure Sensor Pick-Up on an outside wall closest to the
Control Box (roof mounting is also acceptable). Outdoor Pick-Up must be installed with the removable cover
facing up with the metal plate parallel to the earth’s surface. Connect the ¼” tubing (provided) to the Outdoor
Pick-Up as direct as possible to the Control Box. Larkin recommends the tubing be enclosed in conduit from the
Control Box to above finished ceiling. Conduit should also be used when penetrating walls or roof. Insert the
tubing through the hole in the knockout located in the top of the Control Box. Connect tubing to the “Outdoor”
connection (the open port) on the pressure sensor. The “Indoor” connection should already have tubing
connected to the Indoor Pick-Up in the top of the Control Box.
Note: This is required for differential building
pressure control. If unable to install tubing from the Outdoor Pick-Up to the Pressure Sensor in the
Control Box,
contact technical support at 800-322-4036.
Fan Input Power From Breaker Panel: Check the power source to see if it is compatible with the requirements
of the provided system. The AFC-DCV wiring diagram lists the proper Phase, Voltage, and Amp load. Verify input
power voltage before connecting to Control Box terminals supplying VFD(s). Field wire proper Phase and Voltage
from the breaker panel to the correct terminals in the Control Box for each fan being controlled.
