SYSTEM OPERATION
With all of the components installed and wired properly, you can begin using the Pressure Control system. If you
have made no adjustments to the operating range of the transducer, you should be able to input your setpoint and
get your system working without any other parameter changes.
Setpoint:
You can change the setpoint from either the Display menu or the Programming menu. The setpoint parameter is
“St1.” Note: the value you choose must be within the range that the system is currently con
fi
gured for. For example,
if the system is con
fi
gured for 0-1 in.W.C. you cannot set the setpoint for over 1 in. W.C.
Pressure Display:
You can view the duct pressure by scrolling to parameter “b1” on the Display menu.
