OTHER CONTROLLER PARTS & FUNCTIONS
FUSE: “F601” is located on the circuit board near the board-mounted control transformer.
This a 0.125 ampere, slow-blow type of 5mm x 20mm metric style fuse. Replace with same
fuse type and rating.
POWER ON LED: Controller “POWER ON” operation is indicated by “LED231”, Yellow
WIRING CONNECTORS: “TB101” & “TB102”. These are 14-pin plug on connectors. Ensure
all wiring connections are secure by tightening the screw terminals on these connectors.
