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 cir-

cuit board will repeat this cycle two more times in attempt to remove or fix the problem. If this is not successful, the

control 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, tog-

gle a dip switch on the back of the circuit board and reprogram.
