Troubleshooting

1 If a particular Module won't go on or off from the rocker keys on the Mini Timer:
Check that you have power to the outlet controlling the Module and the switch on the
light or appliance is ON.
Check that the Unit Code and Housecode on the Module are set correctly.
Try plugging the Module and the Mini Timer into the same outlet. If the Module doesn't
work in ANY outlet, not even with the Module and the Mini Timer in the same duplex
receptacle (top and bottom) the Module may be defective.
2. If you can't control ANY Modules from the Mini Timer.
Check that there is a time displayed on the Mini Timer and that you have power to the
outlet it is plugged into.
Check that the Housecode on the Mini Timer is set correctly. Try plugging the Module
and the Mini Timer into the same outlet. If NONE of your Modules work in ANY outlet,
not even with the Module and the Mini Timer in the same duplex receptacle (top and
bottom) the Mini Timer may be defective.

Intercom systems

Intercom systems which send voice signals over existing electrical wiring may interfere
with the operation of the Mini Timer when the intercom is in use. If the Intercom system
has it's own separate wiring it will not cause a problem.

Power interruptions

When the power is restored after an outage, Lamp Modules and Wall Switch Modules
will normally be OFF. Appliance Modules have a "latching relay mechanism" and will
stay as they were before the interruption.
This means that when you first plug in an Appliance Module which you have just
purchased, it may in an ON or OFF state (the state it was in before unplugging after
factory testing).
Battery back-up
If you install a 9 volt alkaline battery in the battery compartment of the Mini Timer your
programmed times will be protected for up to 48 hours in the event of a power outage.

Battery test

To test the condition of the battery, press either the "Once" button or the "Security"
button. If the battery is low the battery light in the display will turn on. If the light doesn't
turn on the battery is o.k. If there is no battery installed or the battery is dead the battery
light will be on all the time. It is recommended that you check the condition of the
battery regularly and replace it at least once every 6 months.
