The XCOP1 is a Constant Operating Pressure Control that will modulate the speed of an RT-Series Rooftop exhaust fan to maintain 

a user adjustable negative pressure set point. The set point is adjusted through a pot mounted on the COP circuit board. The operating range of the XCOP1 control is -0.10 to -1.0” w.c.. Do not use with any other series of Tjernlund Inducers/Venters. 

Pressure is measured in a chase or duct at the farthest point from the exhaust fan with the included sensing tube and tubing which connects to the pressure sensing port on the XCOP1. As exhaust volume increases within the duct/chase the resulting reduction in measured pressure causes the XCOP1 control to increase power to the fan. It speeds up to handle the additional exhaust volume and slows down when the exhaust volume is reduced, modulating fan speed to maintain a constant exhaust pressure.
