Corrective Action
Measure voltage at pins 1 and 2 on DIM 2-pin connector.
The voltage should nominally be 24 VAC.
If correct voltage is measured, internal DIM fuse is probably
blown. Unplug 2-pin connector from DIM for 2 minutes. The
internal fuse will automatically reset. Plug unit back in and
check display. If display is still blank, check all wiring, etc.
Verify circuit breaker is on.
Verify transformer primary measures 110 VAC.
Verify transformer secondary measures 24 to 30 VAC.
If proper voltage is found between pins 1 and 2 of the DIM,
all wiring has been checked, fuses have been reset, and
screen is still blank, the DIM is probably defective. Replace
DIM.
Slide finger across the screen diagonally from upper right to
lower left corner.
Enter the DIAGNOSTICS menu.
