TROUBLESHOOTING TIPS
Problem
Nothing happens when a setpoint occurs to turn the load ON or OFF.
Solution
Review programmed setpoints making sure the day has not been
skipped.
Problem
You wish to clear the control’s memory and start over.
Solution
Depress the reset switch to the right of the display.
Problem
Manual override does not work.
Solution
Check the load for proper wiring. Remember, the contacts on these
units only switch what is applied to them. (Dry or isolated contacts.)
Problem
Blank display
Solution
Check the input power source, ensure proper connection.
Problem
Control does not operate after programming.
Solution
If programming was not performed (changing clock time or entering a
setpoint), the control will not update itself. Press the ENTER key and
override the load until the next scheduled setpoint.

OVERRIDE:
Manual override reverses the current output state. Loads that are ON
turn immediately OFF; loads that are OFF turn immediately ON. The
timer displays OVR to indicate that the current load state is the result
of an override. The override remains in effect until overridden again or
until the next setpoint is reached. To initiate override, press OVR
(ENTER) key while in the RUN mode.
NOTE: After an override has been initiated, the OVR will display until
the next programmed setpoint is reached, even if the timer is overrid-
den again. Display will show if the load is ON or OFF.
