Failure Mode
The circuit board is equipped to detect a stuck/locked motor or piston. It will supply power to the motor for 30 sec-
onds after detecting the fault. If there is no change in status the control will power down for 90 seconds. The circuit
board will repeat this cycle two more times in attempt to remove or fix the problem. If this is not successful, the con-
trol will permanently shut down and a telephone icon will appear in the display. The telephone icon indicates that a
service call is required to repair the control. To reset the board, after finding the cause of the problem, toggle a dip
switch on the back of the circuit board and reprogram.
