Step 2: Once steady state minimum desired operating ow is
obtained, perform the ‘Teach’ function on the ow switch. The
‘Teach’ function is initiated by holding down the minus ‘-’ button
on the face of the ow switch for 15 seconds. During this 15
second period, LEDs ‘0’ and ‘9’ will be lit green. Once the
‘Teach’ function is completed, the outer LEDs will ash green
as shown in Figure 46.

Step 3: After the ‘Teach’ function is completed and the outer
LEDs ashed, the ow switch will indicate a new set point
based upon the current ow which should still be at the steady
state minimum desired operating ow.Figure 47 shows a
typical display for this condition. All LEDs to the left of the
SP LED are lit green. The SP LED is lit RED (or may toggle
amber) which indicates that the ow switch is OPEN. Typically,
an increase in uid ow is between 15% to 30% above the
‘Teach’ function ow is required for the SP LED to turn AMBER
and the ow switch to CLOSE indicating acceptable ow.
