Sketch the piping of the system
This is a relatively simple step that tends to be overlooked,
however it can often save hours of time in troubleshooting a
system. Use your sketch to:
• Note flow directions in the system–paying close attention to
the location of the pumps, check valves, pressure bypass
valves and mixing valves
• Ensure the correct flow direction on all pumps
This is also a very useful step if additional assistance is
required.
Document the control for future reference
Before making any adjustments to the control, write down all
items that the control is currently displaying. Include items
such as:
• Error messages
• Current temperatures
• Settings (Program Setup Sheet - Appendix IV, page 52)
• Devices that should be operating as indicated by the LCD
This information is an essential step if additional assistance is
required to diagnose the problem.
Isolate the problem between the
control and the system
Now that the sequence of operation is known and the system
is sketched:
• Is the control operating proper pumps and valves at the
correct times?
• Is the control receiving correct signals from the system about
when it should be operating?
• Are proper items selected in menus of the control for the
device that is to be operated?
