Document the control for future reference. Before making any adjustments to the control, note down
all of the items that the control is currently displaying. This includes items such as error messages,
current temperatures and settings, and which devices 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 the proper pumps and valves at the cor-
rect times? Is the control receiving the correct signals from the system as to when it should be oper-
ating? Are the proper items selected in the menus of the control for the device that is to be operated?
Test the contacts, voltages and sensors. Using a multimeter, ensure that the control is receiving ade-
quate voltage to the power terminals and the demand terminals as noted in the technical data. Use
the multimeter to determine if the internal contacts on the control are opening and closing correctly.
Follow the instructions in the Testing the Wiring section to simulate closed contacts on the terminal
blocks as required. Test the sensors and their wiring as described in the sensor Data Brochures.
Monitor the system over a period of time. Select the application items in the Monitor menu of the con-
trol and reset them to zero. Allow the system and the control to operate over a known period of time
and then record the Monitor items. Use this information to help diagnose any remaining problems.
