Connecting the Controller
Apply power to the Controller. The operation of the
Controller on power up is described in the Sequence
of Operation section, starting on page 4 of this manu-

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.
