| Problem | Solution |
|---|---|
| Blank display | Verify circuit breaker at main panel. Ensure the ON/OFF selector is at ON. Reset the switch using a paper clip. |
| Faded or irregular display | Ambient temperature below freezing point. |
| Cannot switch between 24-hour format and 12-hour format | First, press one of the control buttons so that MAN or AUTO appears on display. |
| Programs do not run as expected | Make sure the switch is properly programmed. Note that -:- - indicates an inactive program. If the switch has been configured for 12-hour format, check that PM appears on the left side of the screen when an afternoon time is displayed. |
| The switch resets itself without apparent reason when used to control an inductive load such as a relay or a contactor. | The reset is caused by the load. Install a snubber (AC130-03) at each relay/contactor. |
