Testing the Controller’s
Outputs
The Controller has a built-in test routine, which is used
to test the main control functions. The test sequence is
enabled when the

button is pressed and held for 3
seconds while in the
View
menu. The outputs are test-
ed in the following sequence:
1. After 1 second, the pump is turned on.
2. After 4 seconds, Stage 1 is turned on.
3. After 7 seconds, Stage 2 is turned on.
4. After 10 seconds, Stage 3 is turned on.
