ADJUSTING THE EXHAUST PRESSURE SET POINT
The pressure set point is adjusted by positioning dip switches 6 - 1 to match the desired setting listed on the Pressure Setpoint
Table below. The factory set point is 0.10” W.C. The dip switches are located on the Red block on the top of the COP2 circuit
board. A dip switch is ON when pulled OUT towards you. A dip switch is OFF when pushed IN away from you.
CAUTION: Disconnect electrical power to COP2 L1 & N prior to adjusting dip switch settings.
ACCELERATION SPEED SETTINGS
Dip Switches 7-8 are used to select drive response time. Slow (30 sec) = 7 ON, 8 OFF, Medium (20 sec) = 7 OFF, 8 ON, Fast (10
sec) = 7 ON, 8 ON,
The Fast (7 ON, 8 ON) acceleration is the factory default. Acceleration adjustment is typically not required unless set points of
greater than 0.30” W.C. are selected or if the vent run is a long length.
